Re: 300 WSM powders

H4350 and H4831 were tried in my gun but did not do as well as IMR 7828 for accuracy.

Re: 300 WSM powders

Boyd, H4350 and H4831 were tried and shot the 175 JLK and 155 Lapua well when seated into the lands but accuracy fell off slightly when off the lands. The 7828 shot them the same whether on the lands or slightly off. The gun shoots 168 and 175 SMK's also just off the lands ( 1/2 inch for 3).
