With a 22" bbl I got about 2730 with the 270 gr TSX with RL15. Supposedly with RL17 you can get more FPS. I had just gotten my barrel when RL17 first came out and you could not find it anywhere so never tried it.

The barnes site has a 270 gr TSX load out of a 24" barrel going 2840 or so over H380.
Also has a load on the barnes site for the 235 grain TSX at 3050 FPS so its not a slow pokey.

I also loaded some 225 grainers when I had mine and thought the recoil was a lot more harsh than the 270 TSX.
