Hey guys, I am back trying some new loads out on my 22" 300 win mag. Brass is Lapua, primer is Gm215m, powder choices are H1000, Retumbo, H4350 or H4831sc. Does anyone have a powder preference and why? My previous load, that I had pretty good results with, was 63gr. of H4350. Mainly just gonna start tinkering and looking for real world experience. Thanks guys
