Ever have a factory case split?

[Blind Bat]

I bought some old S&B 7.62x25 ammo on gun broker to use in my Romanian Tokarev. The other day I went to my local range and fired off 50 rounds. When I was cleaning up I noticed one of the cases had split from the neck to about 1/3rd of the way straight down the case. None of the case showed bulges or flattened primers. Is this anything to worry about?

The ammo came in 25rd white boxes with a plastic separator. The cartridges use red berdan primers. I think this ammo is non-corrosive. Probably made sometime in the 1980's since the box says "Made in Czechoslovakia".

Pics are attached.

I had some 7.62x25 surplus a couple of years ago in 16 round paper packages. I seem to recall it being Czech ammo. Anyway, I had some neck splitting as well with no signs they were overcharged. I talked to my grandfather and he suggested it might be due to the brass being too hard. Seems as good a reason as any. In 1500+ rounds I haven't had any other problems.

I pick up lots of brass, even the Tokarev stuff- it's $2 pound for scrap.

Anyway, about 50% of it is split like you show in your pix. It's old, thin, brittle brass. Happens. It's Berdan primed and not feasably reloadable anyway. Shoot it up and enjoy it while it is available and cheap because when it's gone, there won't be any more.
