bullet mashed into case

[jumbopanda]

I was just cycling some rounds through my 1911 and when I ejected one of them, I found that the bullet had been pressed deeper into the case. How does this happen?

[BroncoBob]

Was it like that when you loaded your 1911?

When you chamber a round it causes set back. Becarfull with rounds that are set back it can cause the round to be over pressure. If a round has ben chamber more than once only use for range time. Don;t chamber a round to many times.

[sorensen440]

reloads?

[USN CHIEF]

Try squeezing the trigger before you eject the round next time.


















Just kidding... DON'T DO THAT>

Perhaps there is a weak crimp or maybe even no crimp on the round. How many times had this one been chambered and manually ejected? If you do it enough times, the rounds will get set back over time. Some commercial manufacturers dont have as strong of a crimp and the bullet can be relatively loose in the case.

Oh ok that makes sense, it was a reload.

Happens all the time. I see it more with Blazer Brass than WWB. Happens to self defense rounds too when trying to see if they will cycle properly.

[AlexBreya]

same thing happened to me, only it was with blazer brass

I would suggest not cycling live rounds at home.....but thats your business...yes set back can cause excessive pressure resulting possibly in a KB in your handgun when you fire it.....

The dummy rounds I have at my office is used a lot in all calibers. Most handgun dummy rounds are like that after a while. We just buy new ones when we need. Rifle dummy rounds are okay. It must be crimp issue.

So what happens if a round does this while you're firing the gun? You would have no way of knowing.

Nope, unless it blows up.

[ripcurlksm]

is it the feed ramp that causes setback as the round is drawn from the magazine and the barrel closes into battery?

exactly, rare in factory ammo, but setback can occur in the magazine of a heavily recoiling handgun or rifle....heck I've seen it happen in a .223 styer scout......I've seen factory ammo were the box was dropped, over half the rounds were setback....


as far as knowing, if you reload crimp to factory specs and test....I just bench test my ammo by pushing the cartrige on the bench looking for setback.....and measuring with calipers to double check OL. to much crimp and you will have the same issue to much pressure and your gun could KB....

if you only use factory ammo, I wouldn't think about it to much just don't cycle the live rounds a lot......
