Is it safe to shoot bullets that have been pushed into the casing?

[Shotgun_Slav]

I have a Glock that doesn't function well with hollow point rounds.

Basically, the nose of the bullet sometimes hits the feeding ramp and doesn't go into the barrel.

This may even partially push the bullet backwards into the brass casing sometimes.

However, I've found that the rounds can still be fed into the gun later. While the overall length of the rounds is slightly shorter, they are not deformed to the extent that they can't be loaded into the gun, assuming the pistol doesn't malfunction again.

Is it still safe to shoot these kinds of damaged rounds?

Is there a limit to how far the bullet can be pushed back into the brass casing before it becomes dangerous to shoot it?

And if so, what's the worst that can happen?






P.S. I've already posted about the feeding problem I'm experiencing with my gun in detail on a different thread, so I won't go on any further about that topic here. (You can read my other thread here if you want to: https://www.calguns.net/calgunforum/...6#post27374636 )

It's going to increase the internal pressure within the round, how much is too much is hard to say.... anything from a few more FPS to having a T-shirt with "Stick a Thumb in it" are possible. While a handgun round isn't a .50 bmg so the chances are it won't become a grenade, it could still potentially damage the gun.

Moving the bullet back even .030" on a SD 9mm can drastically spike the pressure. This is one reason factory SD rounds often have a cannelure in the case behind the bullet.

Got it. Seems like a risky thing to do then. I definitely don't want to damage my gun, so I'm guessing I probably shouldn't try it.

Sorry for the stupid question, but what is an SD round? Does that mean standard?

Self Defense.

I wouldn't shoot them. Why risk a high pressure kaboom.

Gotcha, thanks.

.40 S&W is not tolerant of this at all, especially for the heavier bullet weights.
If you don't reload and can't partly pull and reseat / recrimp the bullets, then you should dispose of those too-short rounds.

I don't know anything about reloading. It's something I'd like to be able to do someday, but just never got around to learning.

How does one reseat/recrimp a bullet? Is there a machine that I can use to do that? I'm curious to know how that works exactly.

Also, I'm using 9mm in the aforementioned Glock. I don't have any guns chambered in .40 S&W, but I'll keep what you've said in mind if I ever get any.

google bullet puller both collet and smacker but yeah fro the small cost throw away

9th edition Speer manual had a note that seating some 9mm loads 1/16" deeper doubled the pressure. AS noted above .40 is really bad too. Case volume and bullet weight for .40 can really create high pressure spikes. Saw a guy kaboom his Glock 22 using Clays, which is fairly fast, and 180 grain coated lead.

Cool, thanks. I'll look that up.

Yikes! I won't be messing around with that sort of thing then. Good to know.
