Lost my notes moving to a new loading room, and my "advisor" retired from the reloading shop, so I'm starting over. (Also load for .223 and .243).

I shoot .221fb in a cz 525 rifle and savage striker pistol: 40-55 grain bullets. Hodgdon manual lists IMR 4198 and RL-7 for most all the bullets, however, I was using ball powder H322 on some of the loads (20vt) as a substitute for one of these powders.

Fortunately I have several un-opened pound cans of powder not listed in the manual: Varget, Hodgdon 4350 and IMR 4064; is there data in another manual to study for .221fb?

The manual lists different loads and powders for the pistol vs rifle. Is that because chamber pressure or barrel length difference between the two guns, or will those loads cross-over? I think both are 8 twist Sinarms barrels.
