True! Pull up the Hodgdon reloading data and just use 139 or 140 grain data, Start half way between min and max and work up .3 at a time. LOA will likely have more effect on your groups than the specific powder or charge weight. It is how I loaded for my 7-08. Horn 139 SPBT in Lapua brass, I started with H4350 and found a good accurate load at 2920 fps with that powder so never looked any further. Best of luck.
