how
I put a scope om my turkey gun last season ( and took it off PDQ). Shot well, but not enough eye relief. Another story...........
Here's how I got on target. I set a backer up at 10-15 yds and put 1" stickers on it. The object was to blow the sticker to smithereens. tI used common trap/field loads for this segment. Once on at close range I moved out to 30 yds or so and shot at a bigger newspaper sized patterning target w/ turkey loads.
The pattern was a tad high.but easily moved down till centered. The close range initial shots, allows for centering the shot load easily, the big ragged holes easy to center on target.
