I've got Lil Gun, AA2230, AA2460 and Varget. Not enough concentration on loads. Too busy working with the bug hole makers in 22 and 6 Br. I need to work on the Fireball. I've got them down in to .03s but not consistant. What's your most accurate load for the .221 Fireball on a rifle platform? 40 or 45 grain bullets?
