Had a chance this weekend to get together with a few buddies and go out to the desert for a shoot. On the table at the beginning of the day we had 10 ar15s a shotgun and and handful of handguns. At the end of the day we had 7 ARs up and running and 3 awating surgery. The culprit.....Tulammo. In the first hour of shooting, a 14.5 sabre defence carbine went down with a shell casing stuck in the chamber. Also in the first hour, a brand new PSA CHF 15" carbine went down with the same problem, however this one was rescued with the help of a hammer and cleaning rod (RIP). The next victim was a 11" carbine gas Ar15 pistol about an hour later. The steel case had its lip ripped off by the extractor. The owner had a DNR order on it, so no CPR was given. The last victim was the PSA again...and again. It was revived again and again, for a total of 3 casings stuck in it. The very last time, the owner swore up and down that he'd never buy cheap @ss russian ammo again. The final body count 3 AR15s, and 1 very sad very bent cleaning rod. A couple thousand rounds were shot that day, a majority of which was probably Tulammo. I didn't run much of it, but any and every problem that came about was with it. I had M855, M193, AE.223, PMC Xtac, MFS 55 fmj and match Fiocchi 69 gr. I didn't get any stuck in my chambers. (thank goodness) I guess the moral of the story is...........bring a couple cheap wooden dowels with you if you run russian steel case ammo. Onna side note, I also ran .223 MFS 55 grain fmj and could not get it to cycle in my 18", rifle gas, more than 2-3 round even with the gas block fully open. I'm guessing not enough oomph to cycle the bcg with a large gas system. My 18"er ran AE and Fiocchi 69 grain just fine. My 16" middy DD barrel with FA BCG ran the MFS just fine for at least 3 mags. There were plenty of guns to go around, and good friends to trying to help with one another. All in all a great day, only 90 ish degrees in the desert with a nice strong breeze that helped us keep cool. Good times.
