I started with 60, and worked it up to 80 grains of 2F. Tight patch,ball,bore combo of course. At 75 grs., it shot good,at 80,about the same,so I'm sticking to 80grs. of 2f Goex. Barrel is a Rice "B" weight,44 inches, angular lands and grooves, 66" twist.
2f is for rifles, 3f is for pistols....Lynton MacKenzie
