All my life, if I hadn't loaded my own, for everything but rim fire, I wouldn't
have been able to shoot enough to become reasonably proficient at the game.
I loaded my Ruger #1 with 140gr. Partitions at 2,940fps. It had a 22" bl. Reloader 19, seems to me, offhand. Same load as in Nosler's book, but got a bit more speed. They listed 2,890 something from a 24" bl.
