CZech 7.62x25 surplus neck cracking + Tokarev

[pomelum]

i heard about CZech ammo being very hot loaded, and something about neck cracking.
are old tokarev designed to take such pressure?
i know all about "they are built like tanks, dont worry" and all. i just want to know if someone know something about this.

is this a factory problem causing the case to crack,pressure or chamber size maybe?

not my image

I have steel casing ammo, and my cases crack but not always.

It crack's only half as deep down as your brass casing, but that is steel for you.

I was wondering what causes that?

A few of my milsurp cases have done this. None of the Starline or the .223 converted brass cases have cracked, so I wouldn't think it's a chamber issue.

Fairly common issue with lots of old East Bloc milsurp ammo, especially Czech and Yugo. A cracked neck is not necessarily a problem, but a cracked base that releases burning gas is.

It is berdan primed = who cares?
