One thing I have learned with trying to shoot 22s at 150 and beyond is that ammo becomes vitally important. Shooting a 1/2" group at 50 yards doesn't guarantee a 1" group at a 100 even if there is no wind. Some ammo was noticeably more accurate at 150 yards but was NOT the best ammo at 50 yards. I have tried possibly every type of quality ammo available and some of the really expensive stuff shot like crap in my rifles and some of it shot lights out!
