Headspace one more time
I have an old Spanish Mauser in 7X57 I use as a trunk gun when traveling the backwoods of Utah. I have checked the headspace and it is barely acceptable. After test firing some rounds carefully I have checked the primers and they are protruding about .008 to .010. I am somewhat worried about a blown primer but they seem to have quite a bit of primer body left before exiting the case and no signs of excessive pressure. I am using the old Federal 175 g. RN. I would appreciate your take on this problem as it is a good do all rifle.
