I've got an H&R USH 20g, gun is far more accurate than I will ever sight it in off the bags and there is absolutely no change in impact when I freehand it. I've only killed 3 deer with it, doe at 100, dink 8 at 40 and a 130 10 at 75ish, all went less than a 100 yds and bled like stuck pigs. Shooting 3" Winchester Dual Bonds.
