I shoot a Black Diamond. I shoot two pyrodex pettets and the 300 grain Hornady XTP. It will shoot two inch groups but that is with open sight and I could not do any better with any gun with open sights at that range. We can't use any type of scope or optical sight in South Dakota during the muzzle loader season. We can if we want to use it during the rifle season but I didn't have a scpoe handy for that this year. I am sure it would shoot better with a scope.
