I just started hunting with a muzzleloader last year. I recieved a .50 cal CVA Kodiak Magnum as a birthday present from my girlfriend. 295 grain Powerbelt & 777 50 grain pellets were also part of the gift. With open sights I was confident and accurate out to 60 yards with 100grains. I put a scope on the gun this past week. I amdead on at 60 yards, but 100 yards is all over the place (no consistency). I was thinking of either dropping the bullet weight down to 245 grain,increasing the powder to 130 grains or both. I am still a newbie in this sport and could use any advice you can give for this type of gun and setup.Thanks!
