I am wondering what is the general consensus (or is there one) as to primer choice for the 300 Win Mag? Powders to be tried will likely be H4350 or H4831 or RL19/22/25. I have generally used CCI 250 magnum primers but have heard recently that perhaps a standard primer (CCI 200 or Fed 210) would be plenty hot and may give lower extreme spreads in velocity. Thanks, Rufous.
