I just finished a Kibler colonial rifle, and wanted to find a load that shoots best in it. Was wondering what generally works best for a ball and patch combo? A .490 ball with a .018 or .020 patch? Or a .495 ball with a .015 patch? I have shot the rifle about 20 times so far with 60grs. of FFF, and a .490 ball .015 patch. I was pretty excited when the very first shot hit the 1 inch orange dot I was shooting at. I could end up burning a lot of powder trying different ball/patch combos. Didn't know if there is a general rule of thumb as to what shoots better. A smaller ball thicker patch, or a bigger ball, with a bit thinner patch? Also are the most accurate loads generally in the 60 to 75 gr range?
