I have a lot of experience with .260 Remington, 6.5 Creedmoor, and 6.5 Grendel.
The Grendel cuts off about 200yds from the bigger boys when comparing the same barrel lengths, which was a lot less than I thought.
So if my 22" .260 Rem is shooting 130gr VLD supersonic well past 1400yds, my 22" Grendel is still supersonic to 1200yds, and doing it with at least 10,000psi less chamber pressure, with 10gr less powder, from an AR15 frame vs the AR10 frame.
