I have two .58 cal roundball rifles, A Kibler Colonial and a full stock flint Hawken with a Hoyt barrel. They both shoot very well with a .575 ball and .020 ticking patch which I use in target loads with 75 gr. of Swiss 3F. No more deer hunting. My lube for at least the last 25 years has been TOW mink oil. I can easily shoot a string of 25 shots with either rifle without cleaning. I always use a range rod. Patches are cut at the muzzle. I gave up on precuts a long time ago. When I hunted, I used a loading block with patches cut at the block as if they were in the muzzle.
