what is the thickest back drop or tree or you have penatrated all the way through with you're ak. for me it would be a 5 1/2 inch healthy tree at about 25 yards with wolf ammo. i also have on tape a round from an ak 47 and a ak74 colide in mid air . also has any one fired thier ak at night . cause when i taped my son and friend shooting my ak .every so many rounds would come out the gun glowing red to orange .and this was during the day.it sure made a good video. it almost looked like tracer rounds. i was thinkin it could be the barrel heating up but then all the rounds would light up right?
