RE: 7mm Remington Mag loads.
I had good luck this past year with the 160 gr. Nosler Accubond, 68 grs. H1000, Fed 210M primer and RWS brass. RWS brass tends to be thicker than most, so this load probably could be increased a couple of grains with other brass, but work up from below, of course. I've also had good luck with IMR 4831, IMR 7828, RL22 and H4831 in this cartridge.
For my next project, I'll be trying out the 140 gr. Barnes Triple Shock along with either RL22 or IMR 4831.
