I started the post regarding 6XC primers and have now shot a new ladder looking for a node at a suggested lower powder charge. Previous ladders were from 39.0 - 40.8 but no apparent nodes were repeatable. I appreciate input on interpretation of the data. Rifle is a custom sporter, Stiller Action, 24" Brux barrel, Jewell trigger, Swarovski 5x30x50 scope, H4350, Berger105H, Shooting Chrony at 25', wind negligible, however shooter may be erratic!!. For reference POA is 1" dia and target 2" dia. Thanks
