I find myself chasing my POI with my scope. What doesn't make sense is that when I change my windage or elevation, say 2 clicks (1/4 moa)--- my shot goes off as far as 4 inches from the intended target.
Sounds to me you may have a bad scope. Do a DM said and mount a known scope and try again at the range.
However glass bedding and free floating a rifle may or may not improve accuracy with a specific load. When you bed a rifle and free float a barrel that was once toughing the stock, like Remington, you change the harmonics of the barrel. It may open up groups with a specific load or it may tighten them up considerably.
What it will do is greatly improve the consistancy of the rifle. Where as "X" load printed 1" on a dry cold day but opened up to 2" on hot and very humid day, it will now consistantly group the same, or very close to, regardless of the weather conditions.
You may have to find another load that your gun likes now that you have changed the way it "acts" when a bullet is traveling down the bore.
