I have a C weight .54 Colerain on my Virginia rifle. For trail walks and such, 65 grains of 2f Schuetzen, a .530 Hornady ball, and .020 Ox Yoke patch shoots pretty good. My hunting load is the same ball and patch, and 90 grains of 3f Schuetzen...shoots just as accurately and hits like the hand of God.
