The reason I mentioned the level issue, I have a 99B chambered in 303 manufactured in 1903 passed down by one of my late uncles with much the same problem. In my case the primers would back out as much as .013", some not at all. My first thought it was a headspace issue so I made a gauge with a .064" thick rim, what the brass measured I was using. The action would lock in it bare, but not shimmed .002".DGD308 said:All I got from smith was the gun has a headspacing issue and that he would never shoot t unless i had to defend my life. It was my dads,so t has some meaning to me. I would love to carry it someday just for that reason.
