Rounds Jammed into Casing

[ak4777]

Are rounds a little deeply jammed into the casing unsafe to fire? Some of my 45's are like this. Like about 3-4 mm deep.

[M. D. Van Norman]

Yes, they are unsafe.

[j1133s]

Yes, they are unsafe.

+1. Creates excessive pressure which may lead to case failure.

A bullet that is too deeply seated will cause increased pressure on the casing when fired and you could get a rupture. I would either reload those or dispose of them. Do not fire them.

Sorry for the dupe, didn't reload the page before posting and didn't see the above post.

the term for this phenomena is "bullet setback"

googling for that term should tell you all you would ever want to know.

hope this helps!

(and +1 to the other responses, firing your rounds as described is not a safe choice)

Are the round in question factor loads or reloads?
Sounds like they were not tapered crimped to the right specification.

they are factory loaded. i kind of dropped them on their face a little. only seated like 2 mm or so. but yeah ill just toss em. not even a dollar anyway. they are blazer aluminum too.

Supposedly they can go BOOM.... in a bad way

[stphnman20]

Yea! BAD!!

i would use a kinetic bullet puller to knock them back to a good oal and load them by hand into the chamber

if you ever find 45 brass with the line on the case or the little knurling about haldway down that was intended to prevent that and i think it is present on most military 45

Given that they are aluminum cased, I wouldn't bother trying to salvage them.

Okay well...the results are in. Too curious for my own good. I checked some specs, Blazer is one of the lighter loaded ones, hence their lower muzzle velocity. So...despite the weaker aluminum casing, I fired the two rounds...and...flawless! It didn't seem to do anything. I personally think its fine because sometimes remington gives some of their rounds slightly pushed in too and they fire fine as well. I think as long as the bullet is still seated straight up, it should be okay...as long as they are not +P+ high velocity loads etc. I know its dangerous...sorry...but...I read some other stuff...yes its a present danger, but i feel its not a huge risk...although its not one ill probably take again. I didnt shoot those looking down the sight tho lol.

Once I fired some old crappy surplus Turkish ammo off my Mauser rifle. Some cartridges had some bullets that were setback. It fired, the cartridge ruptured inside the chamber causing a jam, when it was finally cleared the rotary extractor collar was broken causing a failiure to extract. Lesson learned: inspect all ammo carefully.

Ok, you're nuts. I think you really should toss 'em.

I'm glad to hear they all shot well. I use 9mm Blazer AL ammo a lot, and I've found them to be pretty well made.

With firearms, I'd recommend taking a more conservative approach. For example, I see you've taken some precaution regarding your eyes, but a case failure can also mess up your shooting hand.

But I like how things turned out.
