So I made loads with Varget, IMR4350 and AA4350 and shot them yesterday. IMR4350 had the best result, then Varget and AA4350 was disappointing. However, I tested the three based on the powder charge to have equivalency in fps. So AA4350 may perform better with a different charge. IMR4350 was .3 inches at 100yds. Varget was .75 and AA4350 was 1. I was trying to dial in the Pramm sight, so I wanted all the same velocity with different powders.
