With Norma 7saum brass can go up to 67.5gn 2217 with 150gn LRABs @ 2.830 COL. Problem is the L/R is over 113% giving a very compressed load resulting in marked projectiles from the seating die.
Ran powder options through Quickload and looks lije H414 RE17 and even 2209 can perform better than 2217 with no heavy compression.
Any one running these powders in their Saum?
