Remington model 7 question
This weekend I was sighting in my model 7 SS in 7mm-08 and was surprised that after a real good cleaning that I couldn't hit a pie plate at 100 yards? Fired three rounds through the rifle and it was still hitting 6 to 8" high. I made an adjustment to the scope (VARX III 3.5x10) 8 clicks down and all of a sudden I'm now 3" low? Fired another round to make sure that I didn't have the right hold and it was still 3" low. Adjusted the sight 4 clicks up and now I'm right on the bullseye. So I add another 3 clicks and I'm two inches high. So here is my question: When you give a gun a real good cleaning should it take 6 or 8 shots to get the rifle shooting the way it was before? This rifle was originally sighted in for 3" high at 100 yards.
