I just shot two boxes of these the other day. They grouped right at 2" for a three shot group at 100 yards. That was out of my mossberg 695 with a heavy trigger. Best thing you can do is pick up a couple of boxes and try them out. So far the best i have used, in terms of accuracy and effect on deer, is federals 3/4 oz barnes epander slug. I shot two deer with them last year and the worked great. On was at 60 yards, and the other was out around 125 yards.
