75.0 H4350 with 250 jacketed bullets has been my load for the Norma. 2700+ as I recall. 250s should run up around 2800 if you push it to 338 Win Mag pressures. The 225X should get you a bit more. I've run them with the same load I've used for 250 jacketed bullets but don't recall the speeds I may have gotten though accuracy was plenty. RL15 is sometimes reported to be good with the 225TSX but I didn't find good accuracy in my rifle. Partitions and A-Frames are where it's at for me.
