I've been struggling with this muzzleloader for a nearly a week before I noticed the scope had slipped in the rings. So I went to Sportsman's and bought 2 sets of rings and remounted my Nightforce NXS 5.5x22. I took it out this am and shot these two groups at 100yds with 75grs of IMR 4166 and 312gr Pittman bullets at 2850fps. The rifle is a Remington stainless single shot action, 30" Brux max HV with 6" flat, Jewell trigger, Iota stock, and my 5 port Super Beast muzzle brake. It weighs 14.75lbs but the recoil is mild and it obviously shoots.
