for any and all muzzleloader i shoot, i start with a square load.
50 cal, 50g of fff. that is all i use fffg.
45 cal i start with 45g of fff. etc.
work up and don't be afraid to work down too.
i have 15 muzzle loaders and one wanna be inline. they range from .30 cal to .62 cal
most work best with a square load x 1.5. just my experience.
