I'm shooting a Mossberg 835 24" ported with a .676 Hevi-13 choke. My best pattern to date is 165 in 10" at a laser ranged 40 yds with the long beard 3 1/2" #4's . The two other shots that day were 148 and 154 in 10"/40. Temp was 51 degrees. Best pattern with the .683 Carlson long beard choke was 137 in 10"/40. Also with #4's . Indian creek on the way . Can't wait to test it .
