I have a Maverick 25 cal sniper. Shooting nsa 38.5 at 940fps. Groups at 50 yards are hole in hole. 75 yards the are all touching 100 yards is even good but for the life of me I can’t figure out why I’d be aiming dead center and I’ll have a group go high left high right dead center dead center but low. I indexed my barrel to where at 50 yards my windage and slug are centered. Even at 75 yards I have this happen as well. I’m about to sell all slugs and convert my maverick to a 30 cal 600mm and only mess with pellets.
