Here we must use iron sights during our muzzle loader season. For this reason, i use my muzzle loader during our rifle seasons. Using a muzzle loader with a scope mounted is so very much fun for me. Because i cannot focus on the front sight, Using iron sights isn't very much fun for me. Wishing i could use a scope during our muzzle loader season, has not kept me from hunting. What i do is squint the front sight from looking like an hour glass to looking round; squeeze the trigger. It kinda always surprises me when i kill a deer whilst hunting the muzzle loader season.
