It's me again,I just read that guys post again,if I'm correct my muzzle loader is a rifle,and it has a rifle scope on it for the last three years and remains sighted in from one season to another,I guess it would do better if I replaced the rifle scope with a muzzle loader scope it makes me ask my self "how dumb are you'' I realy thought that nikon was working flawlessly each season when I kill a deer or two with it must be "dumb luck" sorry we cant all be as smart as one person!
