Hornady's factory ammo doesn't come close to those numbers in real-life barrels. Maybe in their 24" test barrels.
The SST for a 20" very nice barrel should be around 2500 ft/sec, the Hdy Black more like 2440. Less MV for a cheaper barrel or for one that has lots of internal friction.
There are some benchmark users on here, maybe they will chime in, but bear in mind that every barrel is unique from the rest. Your MV, to coin a phrase, will vary.
