You are in good shape there. 4831 or 4350 should get you everything you want.

I concur, I'd start with the IMR4350
and try LR primers and see what you get

I'm assuming you meant 4831. I do typos two.

My bad IMR4350 is what I would start with

I loaded up some 4350. Range time next week depending on the weather.

Switching over from lead to copper for California. I have a weatherby accumark 7mm rem mag. 1-9.5 twist barrel. Trying to figure a good powder combination for load development. I have RL 19 and 22 and IMR 4350. Been practically impossible to find RL 23 which I've heard is the most temp stable powder. Has anyone used 19 or 22 for the 146gr hammer hunters?

I didn't mean to hijack your thread. my 7mm is a 1:9.25 twist and I'd like to know what you come up with for those 146 Hammer Hunters if you do use IMR 4350. Someday I'll find some RL 23.

I hope the 146 shoots well for your rifle. I gave them a try in 9.5 twist 7RM and my rifle really didn't like them. Tried the 131 and 120 HH and found good success. H4350 was outstanding. I also was running GM215M primers.
