I cannot get my BP rifle to group. How many shots should I take before swabbing the barrel? With what do I swab the barrel? Should I lube the barrel between shots? I shoot a .50 cal. inline muzzle loader using 209 primers, 2 50 gr. equivalent pellets and the bullet is a sabot 240 gr. all lead hollow point. It is scoped with a cheap Simmons scope. I would appreciate your help.
