Hello Rem, To the best of my knowledge the load should be around 9500 psi.It is a buffered load that I built using info from various sources including Tom Roster and other manuals.I know that tampering with published recipes etc. is frowned upon, but I used to do a lot of reloading with lead for waterfowling and still have my vision and fingers intact.All my mag 10's are nitro proofed for 4 Tons/psi or 1200 Kgs.

Better to keep your mouth shut and be thought stupid,than open it and confirm.
