I thought I had read it here before and tried to do a search and find it and didn't have much luck. The muzzleloading barrel really kicks pretty hard with a 100 grains of blackhorn out of such a light gun so I thought the limbsaver pad would help. I had a cheap scope on the gun and it kissed my brow a time or two and I replaced it with a nikon omega scope with the extra eye relief that should help with that problem. I too have a pro hunter with a limbsaver pad and I know it seems to help a lot. I guess I could have done like you and tried to swap the pads and seen if it fit. Anyway thanks again for the info.
