I'm trying to develop a load for my 6AI with 87 grain Vmaxs. The rifle is a Remington action with a 26" Pac-nor 1-10 twist barrel. I've tried 50 grains of H4831SC and 50 grains of IMR4831 but neither load gave me good accuracy, about 1" five shot groups at 100 yard. I've shot .3" groups with 70 grain Blitzkings so I now the gun is cabable of .5 MOA or better. I'm looking for a powder that will give me good load density, about 3500 ft/sec, and .5 MOA accuracy or better. IF anyone could help I would sure appreciate it.
