Velocity and pressure are closely related. You don't get one without the other.
For a given powder, bullet, and barrel length, if you are getting lots more MV than the book value for the same barrel length, powder and bullet, then good bet you are over pressure.
The 6Arc, like the Grendel, is a moderate pressure round, not a hot rod.
Alternative if you want more MV is to get a longer barrel and make it bolt action as well, so you can go up to 62 ksi. But even so it will not out-perform a 6mm creedmoor, nor will a grendel outperform a 6.5 Creed. You are getting a very effective long-range cartridge at modest powder loads in a compact, AR15 frame. Well suited for some jobs, not so well suited for others.
This last point: means you have to buy another rifle in different caliber... o my!!!
You can thank me later.
