Mosin Crew: Trigger sometimes won't reset on my M44. I was shooting with a friend yesterday out in Colfax and he pulled the trigger but the gun didn't fire. He handed it to me to check out and when I pulled the bolt back it just slid right out. After a few times of working the bolt the trigger reset but I didn't want to shoot it anymore after that. Lately when ejecting rounds a small circular piece of metal has been coming out with the brass every once in a while and I figured it was something coming off of the ammo and just ignored it. Any clue as to what's happening and how I can fix it?
