Today I chronograph ed my standard loads out of my 7 WSM today I have a Brux 26" SS 9" twist bbl. 69grs of Re#19 behind a Hornady 139gr SST produced an average muzzel velocity of 3550
Two new manuals show 3300 fps for max. loads in the 7mm WSM with 140 gr bullets.
My Hornady manual says 3200+ fps with that combination (Hornady manuals are pretty conservative). He's getting 10% additional velocity, that is not unusual or out of the realm of possibility.

How does it shoot?
Never try to educate someone who resists knowledge at all costs.
But what do I know?
