My son purchased a new leica scope to mount on Remington mountain rifle. Mounted with Talley one piece mounts. Got it bore sighted but ran out windage adjustment in the process. Shot at 100 yards. Grouped right of bull and could not bring left without shimming. Thought maybe receiver holes were out of alignment. Transferred set up to nolser rifle, same thing. Is it the scope or the rings? This is my first experience with a Leica. Windage turret only makes 1 3/4 turn total. Any input greatly appreciated!!
