I recently had a rifle built with a Proof Research 24" 1:9 twist barrel. The rifle shoots the factory Nosler Custom Ammo into a ragged hole at a MV of ~3100 fps.
I'd like to duplicate the load and would be interested in the best guess / suggestion for powder / charge to get as close as I can.
Thank you
