Byron,
I have a Burris 4.5-14X42 scope on it and I checked the scope and it is tight. I would have to take the scope off to check the mounts. I have an adjustable IT scope rack that I shoot off of and that seems to be solid. I may just have to take the scope off, check the mounts, and try again. 5" at 100 yards is terrible. I can hit a quarter with my Traditions In-line muzzleloader at 100 yards. Thanks.
