need a 300 saum expert

[Jimmy Nix]

I'm doing some reloads for my DPMS 300 SAUM, and having a hard time finding out PSI limits. Can anybody help me out ?

The Quickload program shows the MAP for 300 SAUM to be 65,000psi. Since the Hodgdon reload manual shows powders up to 64,100psi, then the 65K is correct. That said, DPMS may recommend a lower max for a gas gun. You could call DPMS technical support and ask them.
