4th P,
Didn't mean anything derogatory, just that another persons loads cannot be relied upon in another rifle. Brian is a very experienced handloader so I don't doubt his quotes.
I have loaded up to 76 grains but fell short of that velocity which is a common experience and a reason why I build my own loads caring very little for published data.
Incidently, the only published data I ever experienced that was common to my own chrono readings came from the long obsolete Hornady Vol 2 which used factory rifles to accrue.
