I had a chance topattern my Benelli Nova 12ga 28" barrel today with an Indian Creek Black Diamond Strike .665 and Hevi-13 3" 2 oz #6.
I put a 4" paint dot on a sheet of cardboard (different cardboard for each shot), sighted down the rib and put the red bead on the paint dot.
At 40 yards the center of the pattern was about 8" high and centered. At 50 yards the center of the pattern was about 10" high and a couple inches to the right.
Has anyone experienced this with Indian Creek choke tubes?
