I'm working on a load for a 7mm Remington magnum using H-4831sc, 150 grain bullets. I'm at 66 grains with no pressure signs, velocity averaging a sedate 2900 fps. Depending on what source followed I'm either at or four grains over recommended max, to be honest I'm not certain which direction to go from where I'm at. Rifle is a Browning A-Bolt Stainless Stalker, 26" barrel with B.O.S.S. system.
