I have been having a bit of trouble making the reticle level with the action on some Remington 700's. Used Level, Level,Level and figured the bolt raceway level was not accurate, used a stainless steel rule on raceway in conjunction with a precision level and they were the same! Used a plumb bob and string with levels, same! Thinking it might be me tilting the gun, I had several others shoulder guns with the same results, Can the bolt raceway be out of level?
