Looking in the Hodgdon manual, no. 27. Their max load for a 63gr. bullet is 26.4gr. And pressure is 50,700, and that's on their website listed for pistol data. Now, go to the rifle data, on the website same bullet, 24.1 is max, and pressure is 52,600. I'm loading for an AR-15, and not really interested in breaking speed records, so my previous loads were 1gr under max, and worked just fine. But when I noticed this discrepancy in loads, same cartridge and bullet, one listed for pistol, the other for rifle, anybody got any idea's why??
