.54 caliber is a great caliber. My .54 calibers like 90 grains of 2f black powder and a .530 patched round ball. I get my patches from Wal Mart. Go to their fabric department and get a yard of blue or red stripe Pillow Tick 100% cotton cloth. Its .017-.018 depending on how hard I measure it. And with the .530 ball gives a great seal.

I use moose milk as my lube. I am sure the recipe is around on the site somewhere. But if you want it, I can look it up and send it to you. It works great. As already said, the .54 caliber roundball is a real deer killer. Just a real favorite of mine.

A little tricK I use when loading the rifle. Push a fuzzy pipe cleaner into the touch hole/vent hole and close the frizzen over the pan holding it there. Now dump your powder charge down the barrel. Cradle the rifle, open the frizzen, and slowly pull that pipe cleaner out. You drag powder up behind the vent hole. And you know its open. One little spark through that and its instant fire.

Post a picture of the rifle if you can and we can probably tell you a lot about it. Make sure its nice and clean before you shoot it. You have a good rifle there.
