I have shot a ton in 7.62x39 out of my SKS and Ruger American, and it is reliable, and plenty accurate for what it is. I was buying it for $4.25 for 20 rounds a couple years ago, even hollowpoint.
I haven't shot it yet, but I have several hundred rounds of 7.62x39 HPBT. Surprised to see Boat Tail rounds.
