Ok have really been thinking and read about the 6um. What’s the difference between it and the 6max from Sherman? The 6max is a improved saum with 40degree shoulder. How close would a 6-6.5 prc be in velocity to the 6max or 6um 40? Just trying to say the options. Can get 6.5prc brass locally would be on a 20” barrel plan on shooting 90gamechangers to 115dtacs. Any info would be great.
