Found this when checking someone's magazines where ammo hasn't been changed out routinely and ammo not rotated in the magazine.  Rotate your self-defense magazine rounds once in a while so you don't keep chambering the same round over again.  And replace ammo with fresh rounds depending on how your gun is used and stored.

Looks like a police lineup for gun opponents.  "Do you recognize any these as the one who killed your husband?"

This is very good advice.

Yikes

Those look like reloads. 

GOOD GOD. That could have been one destroyed handgun right there.

I remember giving a few of my set back rounds to the RSOs at Koko Head to dispose of and one of them said "just shoot them off". While my rechambered rounds didnt look as bad as the ones below, I said "I aint taking any chances" and insisted they dispose of them.

third one from the left, the case looks longer than the rest

I've ran across this also. RO said if STHF and you have to shoot, 1 set back round won't harm you.  But if you should a few mags worth, then maybe due to pressure changes.

I now compare my "heads" if I have to rechamber.  But I do shoot my HP rounds about once a year anyways, all my mags so at least 50 rounds worth.

The third one is just offline.  Copper bullet is oxidized.  The cases have creases from the bullet being pushed back.  Looks like this is caused by the case being suddenly accelerated forward while the bullet stays in place during clambering.

These we're cycled a couple times per day.

Isn't crimping supposed to prevent this?

They'll probably fire okay and chance of the gun blowing up is low but not worth the risk.  Could jam due to the creases in the case.  Id like to disassemble it to check if the primer material and powder is still intact.

Yeah not worth the $1.  No be to pake when it comes to ammo. 

Still pissed TSA took 1 HP round from my 50rd box last trip to Vegas.  I want my $1 back.

I'm surprised the revolver crew hasn't chimed in here that wouldn't need to worry about that with revolvers. . .

Inspector?
Stang?

No, revolvers have the opposite problem called bullet jump. It can be much worse than setback.

Well, learn something new every day.  But not quite the same as the issue of unloading/loading for semi-auto.

It's not often where I unload a cylinder after firing some of the rounds.  Then again, my experience with revolvers is pretty much range fun and teaching.

Revolver cartridges headspace on the case rim. Usually you will use a roll crimp for revolver cartridges. Semi auto cartridges headspaces on the case mouth. Usually, you will use a taper crimp for semi auto cartridges. Traditionally, revolver bullets have a crimp ring or cannelure as well to put on a roll crimp. While this helps prevent bullet jump in very high powered cartridges it may not. You’ll find out the hard way if you experience bullet jump. Some feel crimping also applies a uniform pressue holding the bullet in place adding to consistency between rounds. But there is another reason to roll crimp on revolver cartridges. You’ll never know when a friend pops up with a lever action rifle that fires pistol caliber cartridges. A friend had a .357/.38 lever gun and another friend was shooting .38 Special reloads. When the friend with the lever gun ran out of ammo, the friend with the .38 Special ammo volunteered his reloads. Which he didn’t crimp. A round got jammed in the action locking it up. Cost my friend $150 for the smith to take the action apart to get the round out. Expensive lesson. Yeah, I know. Chances are it will never happen to you. But......

I crimp all pistol cartridges I reload.

I was mostly teasing you revolver folks, but thank you for the informative post.  As always.   

I always wondered about the lever action aspect of the rounds in the tube like that.  Personally, I wouldn't worry about the bullet jump thing much since typically, I don't unload unspent cartridges after shooting some in the cylinder.  Best way to unload a gun is to send the boolits downrange.  In a safe direction of course.   

I have heard about this but never seen such a clear example!

Someone mentioned that under some brand's warranty you aren't supposed to seat the round more than two or three times.
