Long time reloader but 1st post. So with the powder shortage, I have these available to work up a load with for my Browning ABolt in 270 WSM with either 140G AB or PT. H4831sc, H4350, IMR 4350, IMR 4831 and RE22. I have the Nosler #6 manual but not the most recent. Just wondering what powder/s you would use to start with. Also, do you use Magnum Primers or just large rifle? The manual suggests WRLM but I have CCI, Fed and Rem Magnum primers as well. I have my favorite powders for 270 Win, 30-06 and 300WSM but looking for ideas. TIA.
