Questionable Brass

If it is only a few, when in doubt throw it out. If there are a large number, contact the seller. Usually they give a few more to make up for a few bad apples.

It is super clean though!

It looks like a mfg flaw in the brass. May split at some time. The dent is just that, got hit at some point.

The double wall one should hold up good, provided you can get dies and custom chamber to utilize it.

I'd load it and shoot the first one. If it splits it splits. The second is a minor bulge from firing, it won't hurt nothing. The third is the very reason why I never tumble but one type of case at a time, and never anything smaller along with them.

A split is really not a bad failure. If it survives your expander die shoot it to failure. You could trim it to 38 special if you need brass badly.

I'd be tempted to keep the third one as part of a collection of oddities, like I did the first .357 Mag round I loaded (many years ago).

Put the third one in your kinetic bullet puller tap it a couple times and things will come apart without damaging either piece. If you do tumble your brass in multiple calibers put the biggest ones in first and let the tumbler run a couple minutes. Then add the next smallest and repeat as needed. They will not nest like that if they are already full of media. Also agree with the others that a split at the mouth that happens when firing is not dangerous but then the brass is toast after.

First one; I'd chunk it. The less hot gas leaking in your chamber the better. (In the event it splits) Second one; I'd shoot it.

The firing cycle happens too fast for any damage to the chamber. If one fired cases that split all the time and that split was always in the same place, yes repeated firing could cause damage. Otherwise the occasional split won't harm the firearm. I will also mention that firearms with fluted chambers (HK91, HK33, SVT40) all get hot gas funneled into the chamber to ease extraction of the fired case. So a little won't hurt nothing.

A rare double wall cartridge. I think it's tactical mil-spec!

I am REALLY curious about what is inside that case. ???

My guess would be .30 Carbine.....

Or possibly .32acp. As it sits from the angle it's impossible to even guess the length of the inner case.

I was going to go to the shop and actually try a .30 Carbine and .32acp in a .357 case to see what that looks like, but I'll refrain from doing that now. But I think the .30 Carbine would stick out a bunch more seeing as it is longer than .357.

if it makes you feel better, I've loaded and shot 357 brass (loaded to 38spl data. 357 fed better than 38 in my marlin) that was split 1/3 of the way down the side. it was split all the way to the case head after firing. Now, I don't really recommend it, and it was in my super broke and low available brass college days, but I bet you're fine.


also, when you pulled the smaller case out of the larger, what was it? 380? 30 carbine?327 federal?

What you're see is brass that was stepped on or otherwise damaged and then resized.
During the resizing process dings and dents get ironed out and the crease and built up brass at the base are artifacts of resizing damaged brass.

I doubt if either case will fail but if it bothers you don't attempt to reload either. Did you order 250 and receive 264?

Winner, winner!
