Sabot loads have much less peak pressure. I can hit about 2800fps and stay under 35kpsi with a 200gr bullet. I mean thats simple to do. Sabots hate heat though so you have to take plenty of time for the barrel to cool down.
Only a handful of guys have posted results with the 240gr sabot version. A shooter for Knight even won a match with that bullet. Results look very promising and that why ive sorta been on Lehigh to produce a similar bullet.
It should be nothing to get that bullet to 2700fps+ with commonly used powders at very safe pressures. Longer semi light contour barrels like that RemAge would be ideal for it.
