Just picked up a tactical rifle in 300 dakota and need some reloading info for it. I plan to shoot 168SMK,200SMK,208A-MAX,and 210 Bergers. I cant find any load data in any of my books. Here are the powders I have on hand H4831,IMR-7828,IMR-4350,IMR-4064,Varget,and a bunch that I know are to fast for it. Any help would be greatful--Thanks
