I have 2 RPRs. One is a .308 and the other is a .338. I was reading an article about proper scope mounting and it said scope height over bore should be between 1.5 and 2.5 inches. Another article said 1.5-1.8 inches. Both of my rifle scopes are over 2.5. The .308 is 2.66 inches and the .338 is 2.9 inches. I read that the lower the scope is mounted the more accurate the shots will be at long range. Do I need to get new rings?
