I've started to have this problem with my Triumph. I had everything sighted in and it shot perfectly. When I took it out on Sunday and shot it at 200 yards I was all over the place. I took it all the way back to 25 yards and hit the bullseye with three shots. Went back to 100 yards and it was alittle erratic but I was in a 1.5 inch group for the most part and I figured the flyers were my poor shooting. I took it out tonight and shot a 100 yards and I could not get a group. I know that it is not my scope. All my screws are tight and there is no play. However trying to slip a piece of paper between the barrel and the forend I cant be done. Is that my issue? Or is the barrel getting further broke in and I need to change my sabots and/or powder charge? I'm using 300grain XTP Mag, 100 grains of blackhorn, and the Crushed Rib Sabots. I just really can't believe this. How can I go from shooting really great groups to having my target looking like I shot a shotgun. So does anyone have any ideas?
