I just picked up a fairly nice Stevens 44 1/2 custom barreled for .225 Winchester.  The firing pin strikes the primer off center close to the edge of the primer, but not on the edge.  I am wondering if this is an artifact of the action originally being made for a rimfire cartridge. 

Other than the primer dimple being off center and offending my Germanic sense of order, are there any concerns I should have?  This is an old conversion (circa 1960) so it has been around for a while and seems well used.

Thanks.
