I went to the range today first time in 3 weeks due to work and rain. I was shooting my MKIII and somehow there was a round in the chamber and the bolt forced another round into the rimfire and it went off. I didn't get hurt just felt a little heat on my hand and alot of smoke. Anyone ever have this happen to them? The pics are of the bullet that pushed and the round that split and went off with bolt open. the guns are my MKIII with the red dot and MKII open sights. The targets are 50 yards the center target is open sights and the two three inch are with the red dot. Using a box from an empty brick as a rest.
