I didn't get the impression he was recommending slower loads for everyone, just that his barrel (at the time) preferred a particular load that happened to be slower than the calibre is capable of. The harmonics of his next barrel was no doubt different.
Also bear in mind that F Class shoots at known distances and only needs to punch a hole in paper. His bullets can be travelling slower than a wet week and as long as they are still stable the rainbow trajectory is not going to matter. He dials in the range, points his gun into the sky and gets two unscored sighters before he needs to be on target for the next 10 to score.
With Grendel it is the smallest case of the 6.5 family. Speeds are relatively slower than other 6.5's so unsurprising that guys are concentrated on getting the most out of what the various powders can deliver. This guy is shooting 308 out to 1,000yds in increments of 100 starting from 300yds. He can afford to concentrate on group size at the expense of velocity. If you are shooting a deer with a Grendel or trying to make 1,200yds you don't have that luxury.
Maximising speed allows for longer point-blank-range dangerous space in hunting. It translates into a flatter trajectory which is more forgiving when hunting or in situation where you need to judge distance to target, or do not have the luxury of sighters (e.g. steel targets in Sporting Rifle competition with no sighters, all scored).
Maximising speed, or at least maximising the peak pressure of your loads also maximises the killing potential of the weapon. This goes along with choosing the right bullet for the flesh you want to shred. If using ballistic tips there is a minimum threshold speed at which they are designed to open-up properly. By deliberately slowing your projectile you shorten the maximum effective range of the gun in this scenario. You could go a slightly heavier ballistic tip which is slower but then your point blank range is compromised. The only reason I can think of when hunting flesh that a slower round is of any use is subsonic with a silencer. And if you done any subsonic hunting (e.g. 300Blackout) you quickly realise it is not much more impactful than bow hunting.
Just depends on what you want to do with your gun and this guy has a very specific use for his.
