Patterned it today, with Imp Cyl @ 25yards using 3” Hevi Steel #3s, the split was maybe like 55/45 over/under my POA. But left to right was probably 60/40. Anyone know how to fix that? Or just keep trying different chokes and loads? I don’t think that explains how much I’ve missed, but I’m sure it wasn’t helping.
You fix it by shooting your patterns at 16 yards and do it with a tighter choke. Then a 1/16 change at the comb will equal approximately 1 inch on the board. Gives you something to judge on aligning POA and POI which in your case will require some comb alterations. The tighter choke will give you a more accurate POI.
Your eye is same as the rear sight on a rifle. Raise the comb 1/16 and the POI on the board goes up one inch. L to R the same.
Addition: Best to have a consistent standing mount and the shooter is consistently impacting the plate in the same place. Tight chokes allow one to see it much better. Modified usually will show a nice impact blob at 16 yards.
