From looking at the posts so far, while some push the max load for the rifle, very few find it necessary. And yet the job is getting done. The information on elk and bear I find real interesting as they are hard to pass through with a muzzleloader projectile from what I have been told.

120 grains of Goex FF and a .530 roundball would be a good load. In my .58 caliber I shoot 110 grains of Goex 2f and that .570 grain roundball and the power of that load is excellent. I am guessing that would have some real bone breaking ability.
