just acquired a m77 6mm rem and Im wondering if anyone would know if ar comp would be a decent powder for this round? Alliant has no data for this, they suggested R19 or 2000mr but since i have a surplus of ar comp id like to try it if I can.
Im looking to shoot 70 or 85gr sierras and in the 243 alliant only lists ar comp for the 70 and 80gr pills, i know the cases are different but since they are so similar is a powder that is suitable for one suitable for the other??
