I was cautious, I bought a box of 20 rounds to test the Tula. I had to manually feed or eject every third round. Thankfully no serious jams.
I have no intention of ever putting that stuff in mine again.
It seems that the Russian stuff is not loaded as hot as most brass. Sounds like it didn’t have enough “oomph” to work the action of your gun. I’ve heard of that happening before.
Some ARs run it fine out of the box, some require some experimentation, like mine. Some just won’t run it.
Unfortunately, I bought a metric sh**-ton of the stuff before I tested it, so I was relieved that I could make it work. It’s great for plinking...and practicing stoppage drills!
Problem solved - don't keep running crap ammo and expect different results!
I really like my Colt AR-15A2 HBAR and my Colt AR-15A2 Government Carbine. I would never load them with Wolf or Tula. I’d rather spend more money on NATO-spec ammo.
