270 wsm loads

[Mountain Goat]

Has anyone tried Ramshot Magnum with 150s?

I use Magpro in the 270WSM more times than not, my go-to powder for the 270WSM. In the few rifles I did load 150gr bullets, Retumbo was a real winner, very accurate and low spread. It did give up some(<100fps) velocity to Magpro and IMR7828. Ramshot Magnum should be one to consider though.
