I have never had an issue with tula, period. 10's of thousands of rounds. Not saying their product is perfect, it stinks, it is dirty, yet it goes bang. It also fits in the 9mm match chambers of the guardian and pm9, along with the 45 chambers. Where as other cheaper ammo like winchester, umc, magtech, pri part, etc does not always seat fully.

While this may have been an over pressure. I did not see that. To me it looked like an out of battery detonation. That is the only way i see the case splitting, ripping at the base like that. Personally I believe there was some build up of gunk, likely from the ammo or poor cleaning, in the chamber. This kept the bullet from seating fully into the chamber. After a few rounds it built up to the point of keeping the back of the case out of battery. Then boom.

Another cause could have been poorly seated bullets. as he fired the first few rounds the remaining bullets moved further forward. elongating the OAL. Finally the cases was not supported and boom.

Both of these can cause this issue at standard pressures. I have seen over pressure failures and they are far more catastrophic. If the cartridge had been in battery, an over pressure would have blown the whole barrel along with the breach like it did. In my exp out of battery detonations only blow the case and the breach. Causing damage to the breach, action and stock.

I had an over pressure in battery detonation on a 22lr pistol. it bulged the barrel to the point it would not come off the slide. Sig replaced it no issues. the rear of the case did not split. That same gun had numerous out of battery detonations, because i only cleaned it when i wanted to torture myself. Every out of battery detonation the case split exactly in this way. I have also seen it on a few center fire rifles of pistol caliber. (older lever actions) chambered in 38/357. where the home reloads were not crimped enough. After a few rounds boom.

My 2 cents in a world of twenty dollar bills.

I though it was out of battery detonation too. The pic gave it away to me. I have tons of .308 in this ammo, and cannot find any recalls on Herters. Either way, I'm gonna shots it in the PTR platform, and my M1A's stay on the diet of brass. The fluted chamber in the PTR guns rips the hell outta brass, literally gouges it.
