Home Forums Reloading Big Game Rifles 300 WSM Pet Loads

BearClan, Alliant's 66 grain load is HOT.
65 is pushing it in my rifles(as in max for me), 64-64.5 is just right and the accuracy is still there. I gained about 50-75fps(using like charges of both powders) over my H4350 loads so that matches up with Mann's article.
