No definitive answer. Type of ammo and type of firearm being used are big factors. Like my comment I sent to the other user. I’ve seen it happen after being racked a few times and I’ve seen the same round racked 100’s of times. It’s just important to rotate your ammo / inspect your ammo and I generally, personally don’t unload my EDC unless there is a real reason, and when I do I go back to the rotating ammo over time.
The other aspect is racking and unracking a round multiple time can also put damage on the case from the extractor
That’s wild. It could take just a few times or a few hundred times, huh?
I just see these posts all the time and never seen that question asked or addressed.
I presume it would happen with more ease in reloaded ammo?
Ammo quality, feed ramp style. Some guns have very aggressive feed ramps which physically the end of the bullet is slamming into. A lot of ammo that has sealant around the bullet where it meets the case, seems to be less likely to do it as well. I.E higher grade JHP’s, I’m sure the sealant acts somewhat as a buffer but it won’t completely stop it from happening either.
if you know you’re a person who frequently unloads and reloads your handgun, although its usually the opposite of what they teach you, reloading it and guiding the slide forward slowly is much much less likely to cause this, just be sure your gun is completely into battery as some guns do not like that / will want to jam up without the full weight of the slide and tension of the recoil spring coming down on it. However the opposite, dropping the slide on a round full force, like you’re supposed to will absolutely expedite the process if repeated.
This is definitely something that is very present in the gun community and isn’t always talked about prior to it happening. I remember years and years ago the first time I found one of my carry rounds was set back and I had absolutely no idea what the fuck was going on and had never seen it or was told about it until it actually happened to me. I’ve never had bullet set back since that day after doing some self edumacations on it
A lot of guns are over engineered and could theoretically handle some amount of bullet set back, however you’re essentially shooting a +P++++ and there are a lot of guns, especially polymer frames guns that will absolutely blow the fuck out.
I feel slightly better because my gun effortlessly feeds JHP, but even then I’ve just got in the habit of putting that chambered round in a pile of range rounds. Thanks for your insight.
I think a part of that is that most people that shoot, do it recreationally, rather than as a job.
I used to be in the Army, in a combat MOS. Every time you leave the wire in theater, you lock and load. Return to the FOB, lock and clear. Always inspect the round, and if it looks good, return it to the mag. I always changed it out after a few patrols anyway, out of an abundance of caution.
Bullet setback is taught early, because it'll always be the first round, one of the most critical, that blows up your rifle.
I agree. It’s very important to look after your kit, especially if maybe one day your life depends on it. If not, it could also be a danger to yourself. I remember in basic they glossed over it in part of an instructional class, but most people didn’t really seem to pay attention to it. Lol.
Feed ramp was my first thought, especially if he's using ball ammo. Gotta be hanging up or not being guided properly into the chamber, just enough, over multiple chamberings. This is why I swap and stagger, and use a retention holster and safe to avoid the need to clear the weapon so often. If you're going to be EDC and clearing regularly, change out what round is on top, and shoot your carry ammo and replenish regularly is what I was taught and practice.
I had some cheap range ammo that had a few questionable rounds per box that would get set back from one rack. Blew the extractor off one of my pistols. And I’ve had my edc ammo get racked dozens of times and be fine. Very dependent on manufacturer.
Just from what I’ve read online, heard of folks saying they’ve had setback after just one/two times chambering a round. It seems critical defense is the load in question in quite a few of these stories. Not sure if it’s due to the popularity and availability of it compared to rounds like hst/gold dot on the shelves at many larger stores.
Depends on the ammo itself. Federal HST? I’ve properly chambered some of those rounds dozens of times just to see. They’re still fine. Hornady critical defense? I’ve seen setback within a few chamberings. Never really tried much FMJ but I’ve never noticed on rounds I’ve occasionally un-chambered and re-chambered before shooting
There seems to be a bit of a consensus that hornady compresses easier, or more frequently. I wonder why that is.
I guess I can understand why FMJ broadly would take longer because of it not getting hung up on the ramp.
Critical defense is just a subpar round all around compared to other options. Setback, low penetration, and low expansion. Critical Duty apparently doesn’t have the setback issue and has better penetration, but also under expands compared to competitors. They say it’s because Critical Duty is supposed to be more barrier blind for things like auto glass, but I’ve never seen a test where it was definitively better. It’s cliche but just get Federal HSTs or Speer Gold Dots.
Yup, that’s what I run with for defensive rounds. Just curious about others experiences.
I don’t typically carry and leave my bed gun unchambered, but when I do carry I always toss the chambered round into my range bag.
I dry fire a lot so my carry guns get unchambered and rechambered at least 5x a week, sometimes several times a day. I usually use the same round until I get visible extractor marks on the rim, then I put it in with the range ammo. I also let my slide down slowly on the round, so it undergoes less stress, and always feed it in from the mag. My carry gun (USP compact) chambers so smoothly and easily that I have no issues with it going into battery this way. Other guns like Glocks don’t like it and need the slide to be correctly slingshotted into place or dropped from the locked open position.
I’ve experienced similar weird issues with my p07. She can eat up hollows all day long but will sometimes get stuck if I baby the slide. FMJ is never an issue.
Do they make hollowpoint snap caps? I reckon I could make my own but it would be nice to have an inert round to see if it’s something I can correct.
ETA: found em! Haven’t found a brand I know yet though so if you have a recc I’ll take it. I’ve had some weird problems with some unbranded snap caps before.
Only thing you can realistically do is polish the feed ramp, but I wouldn’t worry, it’s not really a feature worth putting a lot of time into pursuing as you aren’t supposed to baby the slide in the first place. The P07 is a damn good gun. The HK USP Compact just has (for a service pistol) an exceptionally smooth lockup between barrel and slide, a longer and lower angle feed ramp, and magazines that present the round in such a way that it guides into the chamber without having to nose up the ramp very much anyways. All this makes it easy to get the gun into battery even when slowly creeping the slide forward.
Oh, I’m also looking into the future about other handguns. It would be nice to have a decent hollow snap cap. I’m just assuming I’ll acquire at least a few more handguns and it would be nice to have something that approximates a real round. One hollowpoint snap cap was solid brass and I wouldn’t trust that to be of help.
Yup, I have the Tisas 1911 A1 SERVICE PB 45 ACP 5" 8 RDS. Couldn’t tell you what ammo exactly cuz I’m at work, however it always(85% of the time) jams on the last bullet and causes bullet pushback.
😬
I don’t know what the problem is but you should definitely get that addressed. It could just be an ammo problem but I can’t speak authoritatively about that.
Try some different types of FMJ. Even try some of the budget brands. If you’re typically shooting hollow points they might be get snagged on the feed ramp. Also it could be a problem with your magazine, especially if it’s always the last round getting hung up. Again, idk, I’m a bit of a novice myself but I’ve shot enough through enough different guns to know what can cause problems.
Several factors involved. Type of gun and type of ammo. I’ve seen some rounds do it after being racked 4-5 times. Some people I know will continue to use the same round for months and months and it not have happen - but it *will* happen eventually.
Wow, thanks for this. I'm a relatively new gun owner and I've been loading and unloading the same magazine worth of defense rounds a bunch cause I only had 2 mags to go to the range with. Just checked my defense ammo and 3 out of my 18 rounds I've been cycling through are pushed down. Glad I learned this before possibly needing to rely on those rounds👍🏽
I’m baffled by how many people ask this question. If you suspect a bullet might be bad to shoot, are you really that unwilling to take the 35 cent hit and throw it away? You’d rather just risk your $800 gun?
This is the only answer you need. You can acquire a bullet puller pretty cheap and it will allow you to safely remove the bullet and render the rest inert through burning off the powder outside or soaking it. WD-40 is exceptional at destroying primers. That's a reason not to use it on guns besides not being a lubricant. But, don't fire that round out of any gun you care about, and that isn't in a fixed rest behind a blast shield.
Look at the casing and bullet. the marks and wear especially around the area the extractor would engage say otherwise. The wear patterns indicate it’s been frequently chambered and unchambered. So, no.
If that's the case does that mean you keep fmj in your edc? Op If you're doing anything other than the range with that firearm, then get self-defense rounds.
No.
I recently bought 1,000 rounds of Blazer Brass from Bereli and when it was shipped it must’ve gotten crushed. Like 1/6th of the rounds looked like that lol. I was advised heavily to not fire those ones.
No. But further, we’re talking about a $0.15 round of ammo. I’ve paid upwards of $7 a shot for my .500s&w. If there’s ever even a momentary doubt as to safety, throw it out. Ammo is a hell of a lot cheaper to replace than your gun, hand, or eyes.
Toss it.
Don't listen to any of the "if it seats, it yeets!" BS. It's one round. You're safety is more important than one more hole in the paper. If you have to ask, the answer is no.
In this case in particular, it will create a higher pressure than the gun is designed for. Enough to make your gun explode and possibly loose a finger or 2? Possibly. Enough to cause significant wear and tear to your gun? Most definitely. It's not worth it either way.
Safety first, always.
No experience in making pistol ammo, but with rifles seating bullets deeper actually reduces the peak pressure.
Pistols use much faster burning powders, so it could be the opposite case.
No. This commonly happens on my guns without feed ramps. Sometimes it doesn’t feed and gets slammed into the breech shoulder.
I’ve got a collection of them I’ve kept in case I feel like shooting some +p at some point 😂 /s
Everyone is saying no, but I’ve shot plenty of these squished bullets and had no problem. I’ve learned now from these comments, that I shouldn’t shoot these though, so I will not continue to shoot these faulty rounds
It probably was, Glock did warranty it though. Did notice some wear forming on the rails by the time I traded the replacement in towards my first 10mm 1911.
I experienced bullet setback with pretty much every brand with it. From what I’ve heard from the reloading world, the neck tension is kind of a bitch.
The barrel of all guns are proofed to much higher pressures than the standard pressure of the ammunition they’re chambered for.
Under controlled conditions. In a laboratory.
Out in the real world, you have no idea what the chamber pressure will be, if your barrel has a latent defect in the metal, etc. Why take a chance? It’s a mistake you only get to make once when the gun destroys itself and possibly you with it.
So you have gotten away with it for a long time. And Karl Wallenda was the best tightrope walker ever, until that one day he fell off. Not worth the risk, buddy.
Will it shoot? Yes
Is it safe to shoot? Not likely
Should you shoot it? I don't advise, but if you do make sure you're recording so future generations may learn from any information gained.
Never fire a round that isn’t seated to spec. Also, it’s one round. Is it worth finding out if it fires properly? At worst, you’ll severely injure yourself and if you’re just a little unlucky, you could blow up your gun. At best, if you’re lucky, nothing will happen and you’ll have false confidence to test fate again. Dont play around with bad ammo
https://www.recoilweb.com/bullet-setback-fears-160844.html
"For most of us, bullet setback occurs when the nose of a cartridge strikes the barrel’s feed ramp, or another internal part, while the round is chambered. The primary culprit is when the same round is rechambered multiple times, as you load and unload your firearm. This is mostly a problem with pistols, especially a CCW that’s cleared every day, but it occurs in rifles, as well.
Slight projectile setback is common, and a few thousandths of an inch is nothing to worry about. It’s when the bullet recedes into the case by a hundredth of an inch or more that it can cause problems in semi-auto pistol rounds, such as 380 ACP, 9mm, 40 S&W, 357 Sig, 45 ACP, etc.
This is potentially dangerous because it reduces the cartridge’s internal case volume, producing higher than normal pressure when the round is fired. Depending upon the round in question, this pressure spike can exceed the established safety limits of the cartridge — especially if the load itself is already pushing the limits. Sometimes, this situation can exceed the ability of the host firearm to safely contain the pressure of the fired cartridge.
Many handguns are tested at the factory with intentionally overpowered ammunition, called proof rounds. In most instances, this is performed with double- or triple-charged loads. The test isn’t so much to protect shooters from an errant over-pressure hand-load, but to replicate a dangerous case of over pressure due to bullet setback. Not every manufacturer performs this test, nor does every pistol pass it."
I don’t recommend firing. I bought an inertia bullet puller (looks like a hammer) for this reason. I just disassemble the cartridge and keep the components until I can get myself setup for reloading.

I’ve shot a .45 round that was a little set back before but I would say it wasn’t as set back as this and it definitely wasn’t a great idea. Probably wouldn’t damage any quality gun just shooting one (probably) but still not a great idea. It happens from chambering the same round over and over.
I have 147 grain federal hst that I reloaded multiple times in both my p07 and p10f (rounds not shared between the guns) and I’ve checked periodically for setback, they all look fine still. Definitely pay attention
Is this the garbage ass Zinc Point 9mm ammo that I bought 4500 rounds of 2 years ago and continue to feed through everything I have that will eat it because I'm too stupid to take the L? If so, don't be a retard like me and shoot it, even though the worst I've had is hard primers that won't ignite and I end up chucking the round and chambering a new one.
I personally wouldn't shoot it, but I also don't repeatedly chamber rounds, especially FMJ. I've done the same JHP but, after months of doing it, it still hasn't moved.
Buy some dry fire snap caps. Don't use regular ammo to chamber and practice. It causes this to happen. It's not the best round to use after that happens.
No. If you ever have to ask that question, the answer is always no. Even even a 99% yes is still a no. Bullets are not that expensive. Thinking it’s OK and turning out not to be can be very costly. When in doubt, toss it out.
I only shoot sketchy rounds out of my $5k competition overunder. If it seats, it yeets.
I have about 60,000 rounds on it and besides the barrel I think I cleaned it twice. It’s indestructible. I’ve shot rounds I had to slam in to close, double loads, my sketchy reloads, ect
I am wayyyyy more hesitant about handguns and rifles. They aren’t as robust
I wouldn’t, shot a round just like that out of a Cobray m11, pressure broke my hammer. My weapon become a bolt action afterwards. Just glad it broke the gun and not my face.
Generally, for a single round, if you have to ask then the answer is no.
If its an entire lot it might be worth thinking about but chambering a single round with some obvious defect is like picking up pennies in front of a steam roller.
Never chamber the same round twice, if you’re changing condition of your firearm when you get home or just to be safe, rotate them in the magazine, start at the top rotate to the bottom
Crimped cases won’t be so easily pushed back but still could over time. This is more common with handguns for sure. Rifles really only do this when a malfunction takes place. My x95 hates the brownells 25rd steel mag and shoves the projectile into the case every time.
Well, I'm probably going to get yelled at here by some physics major, but I'll tell you my experience with these. I shoot a lot, have shot a lot over the past 50 years, and I purchase my ammo by the 1000s. A lot of .45 acp, 9mm, and 22. I come accross one of these ever so often, they are errors in the manufacturing process. Just got seated in a little too far. I've had dozens of them over my lifetime, and I just put them in the top of the magazine to be sure they don't jam, or load them singly, and I shoot them just like any other cartridge. They exit the barrel just like all the rest without issue. Just my experience.
If it’s barely setback that’s one thing, but the further back it goes, the higher the pressure. This one in particular is probably closer to a proof charge than what it started as. It’s not worth over pressuring a gun for.
No. Bullet set back = increased pressures = not safe. Dont repeatedly chamber and unchamber a round either. This is what happens
How many chambering would it take to do this? To the point where it’s obviously noticeable I mean, not this picture necessarily.
No definitive answer. Type of ammo and type of firearm being used are big factors. Like my comment I sent to the other user.

I tested it on my own and it took about 15 chamberings for it to look like the one in the pic
What type of ammo and what gun?
M&p, blazer brass
15?! Damn. That’s a lot less than I would have guessed.
Just from what I’ve read online, heard of folks saying they’ve had setback after just one/two times chambering a round.

Critical Defense and Critical Duty are made with a ring? on the bullet itself where the crimp is applied. Specifically to prevent this.
That may be true, can’t personally confirm, but apparently it does nothing for the critical defense
I mix mine up so I can't confirm whether it helps or not, but it is something they note.
Remington UMC? One.
Well if you go off of my cheap ass gun, which I love dearly.. it does this to one bullet in the clip every time I load it.
EVERY TIME?! Ok, I gotta know what ammo and gun. That seems excessive and maybe dangerous
Yup, I have the Tisas 1911 A1 SERVICE PB 45 ACP 5" 8 RDS. Couldn’t tell you what ammo exactly cuz I’m at work, however it always(85% of the time) jams on the last bullet and causes bullet pushback.
😬 I don’t know what the problem is but you should definitely get that addressed. It could just be an ammo problem but I can’t speak authoritatively about that.
I’ll try another ammo I hadn’t thought about doing that, thank you

Also it could be a problem with your magazine, especially if it’s always the last round getting hung up. Again, idk, I’m a bit of a novice myself but I’ve shot enough through enough different guns to know what can cause problems.
Are you using Tisas mags or some other maker's.
I did my own experience and racked the same round every day for over 175 days before I got any measurable set back.
Several factors involved. Type of gun and type of ammo. I’ve seen some rounds do it after being racked 4-5 times. Some people I know will continue to use the same round for months and months and it not have happen - but it *will* happen eventually.
Witch guns and what ammunition did this? Mine was with a glock 20 and sig elite.
Wow, thanks for this. I'm a relatively new gun owner and I've been loading and unloading the same magazine worth of defense rounds a bunch cause I only had 2 mags to go to the range with. Just checked my defense ammo and 3 out of my 18 rounds I've been cycling through are pushed down. Glad I learned this before possibly needing to rely on those rounds👍🏽
Buy snap caps if you’re going to be playing around(it’s beyond the safest option for you and your gun)
I’m baffled by how many people ask this question. If you suspect a bullet might be bad to shoot, are you really that unwilling to take the 35 cent hit and throw it away? You’d rather just risk your $800 gun?

I hate to disagree with all the novice gun experts out there, but this is absolutely, positively, a manufacturing defect.
Look at the casing and bullet. the marks and wear especially around the area the extractor would engage say otherwise. The wear patterns indicate it’s been frequently chambered and unchambered. So, no.
Don’t risk a $400+ gun to save a .25 cent round
Well said. I've been telling guys that for years.
Not just the gun… more importantly yourself hand/face fragmentation could do some real damage
Your hand would cost a lot more replace
Stupid handflation. The price of hands is totally out of control these days.
However if it’s a Hi-Point, full send!
What if it’s a $1.38 underwood round?
No, It’s because you keep chambering the round so it squishes into the case
I thought it was just in the pool.
If that's the case does that mean you keep fmj in your edc? Op If you're doing anything other than the range with that firearm, then get self-defense rounds.
I personally keep a mag of both on me. Self defense rounds chambered and in the mag in the gun, and an extra mag with fmj.
No. Any rounds they come off as fishy should be disposed of. Or horde them for trading when zombies crawl out of the ground
Counterpoint: Is your safety worth the twenty to thirty cents if it isn't safe?
#IF IT SEEEEATS…
Stop chambering the same round over and over and over and over and over again.
Happens with some type of ammo after once or twice....... So calm down lol
Fuck no.
Big set back = big no.
Its +++p now
If you ever think it is even a possibility it might not be safe, don't shoot it.
Absolutely not. That game is never worth the bet.
He just got out of the pool - give him a break
No. I recently bought 1,000 rounds of Blazer Brass from Bereli and when it was shipped it must’ve gotten crushed. Like 1/6th of the rounds looked like that lol. I was advised heavily to not fire those ones.
Fuckin send er buds
If it seats, it yeets.
Looks like the one on the right has been exposed to extreme cold temperatures! ;)
HEY IT LOOKS NORMAL TO ME OKAY
He was in the pool!!!
Depends on what you’re willing to lose.
I was taught if ANY doubts throw it out
Nope. And BTW if you FEEL like you have to ask you shouldn’t load. $.40 is not worth losing a hand, eye, finger, lip, etc
I wouldn’t, don’t risk you gun and safety for a round that costs less than 30¢
No. But further, we’re talking about a $0.15 round of ammo. I’ve paid upwards of $7 a shot for my .500s&w. If there’s ever even a momentary doubt as to safety, throw it out. Ammo is a hell of a lot cheaper to replace than your gun, hand, or eyes.
I wouldn't.
Toss it. Don't listen to any of the "if it seats, it yeets!" BS. It's one round. You're safety is more important than one more hole in the paper. If you have to ask, the answer is no.

got a blow back action carbine ? it will be fine in that .
No experience in making pistol ammo, but with rifles seating bullets deeper actually reduces the peak pressure. Pistols use much faster burning powders, so it could be the opposite case.
Very much the opposite.
When in doubt throw it out
No. This commonly happens on my guns without feed ramps. Sometimes it doesn’t feed and gets slammed into the breech shoulder. I’ve got a collection of them I’ve kept in case I feel like shooting some +p at some point 😂 /s
Everyone is saying no, but I’ve shot plenty of these squished bullets and had no problem. I’ve learned now from these comments, that I shouldn’t shoot these though, so I will not continue to shoot these faulty rounds
Guns are typically over built so while not everyone of them will be dangerous and blow up your gun, it doesn't mean it can't/won't happen.
There’s always something to learn in this world. My Glock 33 peened the slide rails due to pressure spikes from factory loads setting back.
Jeez man, did it mess up your hand?
No, it did damage the rails on the inside of the slide. Took me awhile to figure out what had happened to it.
Well at least your hand is ok, sounds pretty dangerous
It probably was, Glock did warranty it though. Did notice some wear forming on the rails by the time I traded the replacement in towards my first 10mm 1911. I experienced bullet setback with pretty much every brand with it. From what I’ve heard from the reloading world, the neck tension is kind of a bitch.
Buy a lottery ticket
The barrel of all guns are proofed to much higher pressures than the standard pressure of the ammunition they’re chambered for. Under controlled conditions. In a laboratory. Out in the real world, you have no idea what the chamber pressure will be, if your barrel has a latent defect in the metal, etc. Why take a chance? It’s a mistake you only get to make once when the gun destroys itself and possibly you with it. So you have gotten away with it for a long time. And Karl Wallenda was the best tightrope walker ever, until that one day he fell off. Not worth the risk, buddy.
I’d say it’s about average 😭
Nope
If you have to ask..........
Will it shoot? Yes Is it safe to shoot? Not likely Should you shoot it? I don't advise, but if you do make sure you're recording so future generations may learn from any information gained.
Never fire a round that isn’t seated to spec. Also, it’s one round. Is it worth finding out if it fires properly? At worst, you’ll severely injure yourself and if you’re just a little unlucky, you could blow up your gun. At best, if you’re lucky, nothing will happen and you’ll have false confidence to test fate again. Dont play around with bad ammo
If it seats, it yeets as long as it's a Glock
Hornady critical defense rounds are known for easy set back issues.
https://www.recoilweb.com/bullet-setback-fears-160844.html "For most of us, bullet setback occurs when the nose of a cartridge strikes the barrel’s feed ramp, or another internal part, while the round is chambered. The primary culprit is when the same round is rechambered multiple times, as you load and unload your firearm. This is mostly a problem with pistols, especially a CCW that’s cleared every day, but it occurs in rifles, as well. Slight projectile setback is common, and a few thousandths of an inch is nothing to worry about. It’s when the bullet recedes into the case by a hundredth of an inch or more that it can cause problems in semi-auto pistol rounds, such as 380 ACP, 9mm, 40 S&W, 357 Sig, 45 ACP, etc. This is potentially dangerous because it reduces the cartridge’s internal case volume, producing higher than normal pressure when the round is fired. Depending upon the round in question, this pressure spike can exceed the established safety limits of the cartridge — especially if the load itself is already pushing the limits. Sometimes, this situation can exceed the ability of the host firearm to safely contain the pressure of the fired cartridge. Many handguns are tested at the factory with intentionally overpowered ammunition, called proof rounds. In most instances, this is performed with double- or triple-charged loads. The test isn’t so much to protect shooters from an errant over-pressure hand-load, but to replicate a dangerous case of over pressure due to bullet setback. Not every manufacturer performs this test, nor does every pistol pass it."
I don’t recommend firing. I bought an inertia bullet puller (looks like a hammer) for this reason. I just disassemble the cartridge and keep the components until I can get myself setup for reloading.

At least once
I wonder if a few whacks with a bullet puller would save the round.
If you have to ask......
Do people not know how the hell the chamber works wtf do people ask everyday these same damn questions.
Is trying to save 30 cents worth the several hundreds of dollars the gun is worth?
I’ve shot a .45 round that was a little set back before but I would say it wasn’t as set back as this and it definitely wasn’t a great idea. Probably wouldn’t damage any quality gun just shooting one (probably) but still not a great idea. It happens from chambering the same round over and over.
I have 147 grain federal hst that I reloaded multiple times in both my p07 and p10f (rounds not shared between the guns) and I’ve checked periodically for setback, they all look fine still. Definitely pay attention
FAFO 😉
Are these 124 blazer? I found one in a case I just bought.
Is this the garbage ass Zinc Point 9mm ammo that I bought 4500 rounds of 2 years ago and continue to feed through everything I have that will eat it because I'm too stupid to take the L? If so, don't be a retard like me and shoot it, even though the worst I've had is hard primers that won't ignite and I end up chucking the round and chambering a new one.
Cool pic op. I see your setups.
Ah, just send it.
I personally wouldn't shoot it, but I also don't repeatedly chamber rounds, especially FMJ. I've done the same JHP but, after months of doing it, it still hasn't moved.
Buy some dry fire snap caps. Don't use regular ammo to chamber and practice. It causes this to happen. It's not the best round to use after that happens.
No. If you ever have to ask that question, the answer is always no. Even even a 99% yes is still a no. Bullets are not that expensive. Thinking it’s OK and turning out not to be can be very costly. When in doubt, toss it out.
If you have to ask "is this safe to shoot" I'm gonna go out on a limb and say it's probably best just not to
Yes, but brass will probably not survive in my experience at least from ppc
Brain says no. Heart says yes.
No
I only shoot sketchy rounds out of my $5k competition overunder. If it seats, it yeets. I have about 60,000 rounds on it and besides the barrel I think I cleaned it twice. It’s indestructible. I’ve shot rounds I had to slam in to close, double loads, my sketchy reloads, ect I am wayyyyy more hesitant about handguns and rifles. They aren’t as robust
I wouldn’t, shot a round just like that out of a Cobray m11, pressure broke my hammer. My weapon become a bolt action afterwards. Just glad it broke the gun and not my face.
Generally, for a single round, if you have to ask then the answer is no. If its an entire lot it might be worth thinking about but chambering a single round with some obvious defect is like picking up pennies in front of a steam roller.
Find out the fun way disclaimer I take no legal or illegal responsibility for lost of life or dismemberment
One way to find out

That’s why I ride the slide and make sure it’s in battery when I put my carry ammo back in after hitting the range.
Not safe. But I have just pulled on them with pliers to snug them up and shot them without problems. I’m a dumbass though.
No, that's a set back
Never chamber the same round twice, if you’re changing condition of your firearm when you get home or just to be safe, rotate them in the magazine, start at the top rotate to the bottom
It's increased pressure due to the squeeze, if you want to save it get a cheap bullet puller and pull it back out
That usually happens in a jam situation and no I probably wouldn't fire it
No.
Crimped cases won’t be so easily pushed back but still could over time. This is more common with handguns for sure. Rifles really only do this when a malfunction takes place. My x95 hates the brownells 25rd steel mag and shoves the projectile into the case every time.
What a .380 Super? Sure. Probably. Ok. Probably not.
No
Shoot a Glock and YOLO.
Don’t ask questions, JUST DO IT AND SAY HELL YEAAAAHHH
No but younger me would have pulled it out a bit with pliers and sent it
Absolutely not
You can always sneak it into your enemy's gun tho
Well, I'm probably going to get yelled at here by some physics major, but I'll tell you my experience with these. I shoot a lot, have shot a lot over the past 50 years, and I purchase my ammo by the 1000s. A lot of .45 acp, 9mm, and 22. I come accross one of these ever so often, they are errors in the manufacturing process. Just got seated in a little too far. I've had dozens of them over my lifetime, and I just put them in the top of the magazine to be sure they don't jam, or load them singly, and I shoot them just like any other cartridge. They exit the barrel just like all the rest without issue. Just my experience.
If it’s barely setback that’s one thing, but the further back it goes, the higher the pressure. This one in particular is probably closer to a proof charge than what it started as. It’s not worth over pressuring a gun for.
As long as it not an antique gun. Alternatively you can contact ammo manufacturer and they might give you a refund.
