My cousin was shooting and this is what happened on the first round out of a particular gun.

Blazer aluminum case. Any idea what could cause/contribute to this? Would a cold barrel, bullet set back, or anything else you can think of cause this or was it just a bad case?

Did the gun cycle normally? Bullet hit where you aimed? If so, probably just a defective case, what about the rest of the box, or did you stop shooting?

If not, I've seen cases split like this from people shooting 9mm out of a .40S&W. These guys were having all kinds of jams and poor accuracy out of their Glock 22, complaining about the cheap Blazer ammo (Academy used to sell it for $3.86/50 back then) when they noticed the ammo was 9mm & the gun a .40 -- they went home with their tails between their legs :)

I wasn't there so I'm getting it second hand. Only one failure, the first round. It was fired out of a Sig somethingorother.

I had a split brass case that was for a factor 148 gr. 38 spl target wadcutter load?

Any case can split if the metal is not properly prepared.

I come across the odd split brass case when reloading range pickup brass. I find them when the bullet seats with about zero effort. As far as I can tell it's not a huge deal. The splits in brass cases are not usually that obvious though.

Was there some indication that made them check that case? If the rest of the box fired normally I would say a bad case. Ammo comes in aluminum cases because it's cheap. ;)

My guess would be defective casing. I've seen enough brass, predominantly rife that exhibits a Y-shaped fold to think that was the culprit here. While processing a recent batch of 1,000 once fired .223 I came across about a dozen with just such a fold or hairline splits at the neck.

I have the luxury of knowing that every center fire round I load in my firearms was inspected before loading personally. Preparation takes some time but I appreciate my fingers and eyes being intact.
