T Z 79 rupture

RMA1 · January 12, 2009, 00:03

I have read the thread on T Z 80 in just the last couple of days, went out to shoot some of my surp ammo today, lots of T Z 79. After the smoke cleared and the stinging in my face stopped, I found the offending case, T Z 79. Is it all T Z ammo that is bad, or did I just get a bad one? No blood by the way, or damage to my gun. The case split from the primer to about 1/4" north.

People tend to focus on TZ80 because it is notoriously bad, but all years and headstamps in the bulk pack, mixed headstamp scrap Israeli ammo is potentially bad. You are still taking a risk if you only remove the TZ80, as you found out. It is pull down ammo.

Unless it's new I have sworn off the TZ head stamp.

Here is a round of TZ 87 the shit the bed in a G3.

It caused a short cycle failure and a bunch of smoke but after clearing and lookie loo everything was fine. The marks on the bolt head brushed of with a bronze brush. No damage.

Nonetheless... No more TZ for me.
