I just put a Nikon inline xr on a Thompson Center Triumph 50 cal. The scope is mounted on a one piece talley base. Im shooting federal premium primers, 250 grain power belt aerolite bullets, and triple 7 firestar pellets. 100 grain equivalent on the pellets.

At 100 yards, I'm hitting anywhere from 6 inches above the bullseye to 6 inches below and the same left and right. Im shooting off of bags. I feel very confident in my shooting ability, just not with this gun.

This is my first muzzleloader. Im cleaning the barrel after every shot. What am I doing wrong? Should I take the scope off and start over making sure everything is torqued right? Help.
