I've only had my new KRB out once so far. After I mounted my scope I took it to my uncle's farm and here is a group from 300gr XTP's with Crushed Rib sabots, 2 pyrodex pellets, and Remington Kleen Bore primers. Started out way left at first and kept adjusting the scope until I got this 4 shot group at 25 yards. Then adjusted up for the last two shots.
