I know this isn't an AR related complaint, but it's about Tula. I got a box of 50 for my M1 Carbine and went to the range. After 35-40 rounds, the rounds started to fail to extract. Well at that point it pretty much turned into a single shot rifle. I'd shoot, open the bolt, take my Mosin's cleaning rod, ram the empty casing from the chamber, recharger the round, repeat. Well I got some Tula 7.62x39 for my SKS, knowing it could shoot darn near anything I could put in it. I had one double feed, but that's cause I had my SKS on single shot mode. Ill continue to get it for x39 cause its $5.17 a box at Walmart.
