Wow, that's pretty amazing considering I was blowing primers out trying N110 and 155 lapuas and getting less than 2000 fps????
Case packed with 20 grains???(don't remember) RL10x with 155 lapuas got 2000fps from 20" bolt. Nice groups too. Shot it at a 600 yd match. Took a few shots to get on paper since the actual BC at that FPS was about .100 less than advertised. But once on keeping it on paper was no prob.
I think my 125 TNT load was doing 2375 from a 11" bbl. Very hot load. Brass was pretty much junk after using.
Bolt gun got to 2500 fps if I remember right.
Those advertised velocities would be more reasonable in a 7.62 x 40mm.
