Home Forums Reloading Big Game Rifles Best powders for 270 WSM: 140 gr, 150 gr bullets (VLD's).

I use Lyman 49 data and a chronograph with 150 grain bullets and IMR 7828. I add a grain when working with 140 grain bullets. No exotic bullets, just Partitions, Grand Slams, and Hornadys'.

I get a very accurate 3015 fps with the 150's.
