No different than any other Muzzleloader. Start light and work up. 530 caliber roundball with pillow ticking, greased with your lube of choice. I use bear grease and beeswax, but there are lots of alternatives. I would start with about 50 grains and work up 5 grains at a time until you find a good accurate load. I hunt with 80 grains in my 54, and some guys I know go as low as 70, others 90-100. All depends on the gun.
