Has anyone used Wolf 7.62 X 39 MM Soft Point Ammo in their AK-47's? I've got a line on some that's the same price as FMJ Wolf, and I'm tempted to try it. However, I wondered if anyone has had any feeding issues with it due to the tip becoming deformed? I don't see any reason it wouldn't run dependably, but I was just looking for some input from those who have tried it in their AK's.
