I agree on getting the speed. I have a .300 Win Mag already. Odds are, I might not ever need something bigger than a .308 Win, but it's nice to know I have it if I do need it. I do sometimes wonder if I should have ordered my Sendero in .300 Win Mag.
But, Im trying to obtain 3100-3150 with a 200-210gr bullet, and get 1/2" or less groups. I'm working with Retumbo, Fed 215 GM primers, and Rem brass.
Tang trying to get that kind of speed with a 300 win mag ! To get those velocities with a 180 gr would require a max powder charges.
