I pulled firing pin and spring seemed ok. Maybe dirt just got into and jammed pin cleaned up and snded rough spots on pin surface put back together. tried out on a couple of brass with just primers working now will try out at gun range on live ammo. The little line is hard to tell I looked at in a magnifying light and glass at work. The line might have always been there? I just now looked at the face real close trying to figure out firng pin problem.
