You may well be onto something there.
He may also have been talking about the 6.5x47 Lapua - a great case that equals the 260 Rem with bullets in that weight range. It is also capable of withstanding extreme pressure better than most. The 6.5x47 Lap has a H2O capacity of 48gn, the 260 54gn (but it loses more with seating the bullets deeper). IIRC the Grendel is fully 10gn under the 6.5x47 Lap case.
3080fps is quite doable out of a 24in barrel with the 6.5x47 Lap case and a 123gn Scenar. Stiff, but doable.
I just can't see those velocities with the Grendel case. Not if you want to extract it anyway. The CZ action, or the Mini Zastava are good, but their qualities are immaterial as the brass will liquify at pressures needed to drive a 123gn Scenar at 3080fps from a little Grendel case.
