Jeff,
No CZ yet. Once I got started reloading, I've let my rimfires collect dust. Once I get my loads established for my centerfires, then I will land a CZ.
So far my 357 likes W296 for jacketed bullets and H4227 for cast. WC680 is a work in progress. It is showing some potential.
I need to spend some time on my 30-30 so I can get a card in.
Have you tried any Varget? I see you are fond of Blc2.
The only powder I have to shoot in the 30-30 is IMR4198, IMR 4064.
I'm wanting to get a pound of something but can't decide which one.
W748 has given me an itch, but it doesn't seem as versatile as some others.
