As a side note, I used some Brown Bear 7.62x39mm ammo I picked up at a gun show last year in Regina. That ammo stinks and is the worst ammo I have ever shot through my 7.62x39mm rifles. Accuracy was awful, made norinco silverbox look like Lapua Match ammo. It did not group, it patterned. Tried it in several SKS rifles, CZ858 and a CZ 527. That was for the Brown Bear FMJ loads. Wolf JHP ammo is less accurate that czech ammo, group sizes were about double for Wolf vs. Czech. The most accurate surplus steel cased I have used is Norinco Silverbox, shoots about 2.5 MOA out of my 527 consistantly. Handloads in comparison are a solid 1 MOA for multiple 5 shot groups, measured edge to edge.
