I used 7.62×39 millimeter russian rounds, the gun misfires once, then the shot goes through the shoulders, down through the vitals, and through the other arm. Then i shot in the head twice point blank to make sure.. I’ve gotten a few responses about the gun jamming… What happened is that I got a misfire.In fact, the bullet that i took out in the video has a mark where the firing pin hit it. in other words, the firing pin didnt have enough force hitting the firing cap. Thanks for all the compliments!!
