I've included a link to a video I shot today, shooting a stock Norinco M305 with 7.62x51 NATO ammo. First 30 seconds at regular speed, second 30 seconds in slow motion. It worked fine until I mounted a scope bracket.
Shot 25 rounds at 100 yards. 1 means reload success, 0 represents failure to reload.
10010 11000 11010 11011 11100
44% chance of failure to reload. Ouch!
Please help. I want to love this gun.
