270 wsm

bcc040401 · Tuesday at 1:02 PM

I'm having a 270 wsm built on a Defiance xm+ med action. 22" barrel, 7.5 twist. I am looking for powder and primer recommendations for a 165gr nosler accubonds LR or 170gr berger elite hunter and adg brass

Welcome to the forum, sounds like a super nice build. Hope you keep us up to date on how it turns out for you.

I don't have a 270 WSM but do have a 6.8 Western. Based on that and my experience with a very similar round look at Retumbo, N 560, N 565, Magpro or even H 4831sc. You should be able to get a bit more speed over the 6.8 Western if it's set up the same way with the bullets loaded out more.

Welcome to the forum.
I don't have my 270wsm anymore, but when I did the heaviest bullets I loaded were 150g ABLR. I used RL26, Magpro and IMR 7828, with CCI LRM primers.
Retumbo and Magnum should work well too.

That is the plan with the medium action to be able to shoot the heavier bullets while keeping good velocity.
