Well, went out and shot this morning. Was in the low 30's and windy, mixed clouds and sun. Got all set up to shoot off hand and pulled the trigger and no boom! Looked and the tip of the firing pin had broken off. So, I carry spare bolt parts and a combo tool and changed the firing pin out. Took about ten minutes. By then was about frozen but shot all 3 positions and was very pleased with the sight picture. The 100 yard range we shoot at is east shooting west so we have light coming over left shoulder and varying shadows on the targets. This is the best I have seen the sights and target in years. I did adjust the location on my glasses for each position.....offhand, sitting and prone but it wasn't much more than an eighth inch change if that. Just put my thumbnail on the edge and had a finger on the eye pal, and nudged it in the direction I wanted it to go, the thumbnail would hunker it up enough to break it's hold and allow me to move it. I was afraid that there would be decreased light levels that would not allow me to see the target but that was not the case.
Am very happy with the results, groups tighter, especially sitting. All scores in the black! Can't wait to get out and shoot again.
