I had a Winchester primer leak in the corner of the primer cup a couple weeks ago in my Model 70 7-08. This was with a moderate load. It is a couple grains below max. I shot silhouette with the rifle yesterday and had three more do the same thing. This was also with moderate loads that have never given any trouble. After I saw it I looked at the bolt and found a pit in the bolt face.

I would like to know what the best way to fix it is. It looks like it would clean up with about .010" taken off the bolt face. Is that good way to go or would it be better to weld the pit and reface the bolt?
