I just bought a 338 win mag awr remington. Got my scope mounted, rings lapped and off to sight it in. Well the gun groups great except for the fact that it shoots 4" right at 100 yds with the windage bottomed out all the way left. Tried another set of rings I had same result. I feel sure its the holes arent square to the barrel. Someone I trust who knows everything about scopes and mounting them says he thinks we can corredt this with a set of S&K rings and bases. I know nothing of these. Anyone ever use these to correct this?
