I couldn' t agree more then already stated. Black powder FFg for the main charge somewhere in the 70 grain range for starters with a .015 pillow tick patch for your T/C Hawkins. Pre-cut patches are easy to use, but I never use the pre-cut patches. I learned a long time ago, get yourself some cotton pillow tick and cut it in strips 2" wide, lube them and after your seat your roundball cut your patch. The more consistant you get with your loading the better your accuracy will be.

Black powder FFFFg for the priming pan. Swab between shots with a wet patch. Black powder fowls very quickly, but as many of these shooters can tell you, it works great. I actually always got excellent shot groups using black powder, but changed over to Pyrodex Select because it burns a " little" cleaner.

The only difference I made when I got my set up 25+ years ago was I went with a .54 caliber T/C Renegade and because Wisconsin allows the use of cap locks, I went with the percussion rifle instead of the flint. I always liked the bigger caliber, but you have a great rifle. I mean this. The .50 caliber will take anything you might ever want to shoot. I am guessing you got the 1-48 twist. If you did, you will be surprised at how well the Hawkins shoots conicals. I shoot them also. I load a 300 grain that I make myself. After you find your rifle' s favorite load, be sure and let us know what kind of results you are having... Good shooting!
