Does anybody have a milsurp that just won't shoot cast right? Out of a large collection I have 2 that continually lead the barrel no matter how fat I make the boolits - a Remington 1903 made in 1942 with original barrel and a 1916 Gewehr 98. I have gone up as fat as .316 with the 1903, and it leads the barrel yet when I load jacketed it will shoot 1.5 MOA. The Gewehr 98 I went as fat as .330 and same results. Both are loaded with powder coated and gas checked boolits and they have been slugged. Makes my head spin! Any ideas?
