This is a follow up to the question I asked a couple days ago about the change in horizontal zero from 100 to 500 yards. The gun is a XP-100 by Nelson Berger chambered in .222 Rem Mag Imp and shooting a 52gr A-Max at 3200fps. Well...this AM it was dead calm so I jumped on the Raptor 660R and posted targets out to 500 yards. After some careful study of the scope I could see a slight cant...adjusted accoringly, rezeroed at 100yd and dial in then fired a group at 300 yards...dead perfect windage and elevation. Dialed to 500 yards and let three rounds fly...jumped on the Raptor and scooted to 500 yards. All three rounds were centered on the bull in a 1.5" group. Problem fixed........thanks fellas!!
