Re: 270 wsm load for vld 150
I don't use any Reloader powder for my 270 WSM but with loading anything, but especially the Bergers I would find where the bullet touches the lands. You need this as a base line to know just how far of the lands you are so you can tune the seating depth and know what's going on.
The Alliant web site has a load for the 150's with 60gr of R19 so the 56 should be good.
