Only thing I’ve had happen to me, so far, was a cracked windage screw on the rear scope mount of a Kimber 84M. The rifle zeroed fine. I took it deer hunting and had a coyote wander up to me. At 25 yards, I couldn’t resist and took a shot and missed. I missed a buck later that day on another easy shot. As I was looking the rifle over at camp, I noticed the screw had cracked on the mount and was no longer holding the scope in place.
