7mm WSM powders

[jja600]

H4831SC and 168gr Bergers 2965fps shoot very well in my (now my friends) Browning Abolt 22 in barrel.

Ramshot Magnum would be a good choice as well and is reasonably available.

Hello, new to the forum here.
I am shooting a stock Winchester model 70, 7mm WSM. I'm loading new Hornady brass, Hornady #28452 SST 162 grain bullets, using CCi 250 primers.
I'm usually hunting in or near the Bighorn mountains of Wyoming for mule deer, elk, and antelope. Just wondering if anyone has an opinion on the best powder and amount to use.
Most of my hunting targets are 300-500 yards out, but I'm looking to extend that for elk, as crawling gets old quick. LOL
If anyone thinks I should change up the lead or primers I'm using also, please speak up. I'm new to reloading, but working with a friend who has a lot of experience reloading, just not with the 7mm wsm.
Thanks in advance!

I have a 270 wsm and use RL16. I've used H4831sc as well as H4350 with 130, 140 gr bullets. I would use one of these temp stable powders. For <140 gr RL16 or H4350, for 150-170 H4831sc, 180+ H1000 would be where I'd start with a wsm. Coal may be an issue with longer hvy high bc bullets in that action.

It's obviously hard to come by but I've been running RL26 and 175/162s for a few years. Impressive enough to keep me away from PRC. Matching performance from what I read with a few grains less powder and a SA.

Will work for me till I can't find brass anymore.

I have found no other powder than VVN 560 to deliver stellar accuracy and velocity in the WSM calibers. I just use the loads listed in the VVN reloading brochure.

RE17, 22, 23, 26, & Viht. N560 in all my 7mm WSM's. I wouldn't be afraid to shoot any of those powders again they all have done well with various bullets from 150-180 grains. I'm currently using N560 and RE23 mostly, CCI 250's & Federal 215's. Now that Lapua makes 300 WSM brass I've got loads of quality brass.

Not too different from my 7 SAUM. RL 26 or 23 works well. H-1000 reportedly works. Lots of people use N560 or 565 too. Those are where I'd start.

Do you think Lapua will ever make 7mm wsm brass, or will they just expect us to neck them down? LOL
