Hi all!

Just got 320 rounds of czech surplus 7.62x25 and decided to inspect them after finding a split case. 21 have me a bit concerned about their safety so I've set them aside. 1 of those 21 has what appears to be a squashed round which I know isnt safe to shoot. The other 20 have a split in the neck of the case in the exact same spot (at least its consistent in its crapiness!).

I suppose I'm looking for guidence on the split cases, they dont seem to be split all the way through. Has anyone seen or experienced this? With 20 of 320 cracked im guessing it would have been common in this lot, if not more. Is it safe to shoot? I really want to take my new tok out, but can't risk messing up my pretty mug!

Give them to me, I will shoot them and tell you if it was safe.

PS. Personally, I would shoot those with hairline crack. I'm not so happy with those that have the bullet in too much.
 
You have the desirable brass cased Czech ammo. I have some very old brass milsurp ammo, and cracked necks are not rare, and 21 out of 320 is only perhaps a bit high.

I noticed the red writing on the ammo box. I understand that it means "Repackaged".
 
Split necks are not an issue when you dispose of cases after firing. If you plan to reload its no good after. Berdan primers are also difficult to find.
If your tok is in good shape then it will digest even the pushed in bullet rounds as well.
I'd get an innertia bullet puller and tap those bullets just enough to push them out to the original length and recrimp them after in the seating die.
If you don't have equipment then its discard if you don't feel adventurous.
 
The Czech cases are known to split at the neck and it's more or less by design. Thick enough to not rupture but thin enough to save money.

If the round is over seated like that I would discard it or pull the bullet and save the components.

Where did you come across this info?

If I remember correctly it was from Marstar directly. It's not all Czech 7.62x25 but a certain lot they brought in.
 
I believe that's called "marketing"; a hi-tech way to explain the crappy ammo they sell that dangerously splits brass cases.
"known to split at the neck and it's more or less by design" - Hah! My BS meter is pegged at 110mph.
 
Definitely not a design aspect of this ammunition
Split necks can happen when brass is brittle or steel cases are fatigued due to pressure during firing.
Mostly its the divots in necks that keep bullets in place when seating them at the factory that cause the split.
That's why some vendors come up with fairytales about split necks as though they suppose to fail.
Even if some cases crack its not a big deal as its not reloadable brass anyway, but it may be an indication of
How old that ammo is
