Started developing some loads for upcoming 300 WM. Loading 165 Gr Nosler Ballistic Tips. First used 75 Gr RL 22, Next 80Gr H1000, and then 74Gr IMR 4831, all with Fed 215M Primers. Loaded 3 bullets each and shot for group. My best group was with H1000 @ 80Gr, .75" @ 100yds. Has anyone else tweaked this load?
