I gotta a super black eagle 3 1/2 with a 24" barrell and i got an issue. with federal premium 6 shot at 40 yards it scattered a bit too much. switched to hevi shot # 5 and WOW 40 yards wrapped the target up. at 50 yards not so great. would getting a longer barrell help me out, or do i need to spend 80-100 dollars on a choke for this thing.
