Hi Jeff, in the three 22" 338 WM's I've had both IMR and H4350 gave over 2,800 with 225's... depending on the barrel, 2,825 - 2,850.
If H4350 doesn't work accuracy-wise, I've found IMR4350 will often give better accuracy.
However, I've honestly never found a need for a bullet heavier than the 210 Partition on elk (2,950-ish)... they just whiz right through and drop stuff DRT. I never used the 200 NBT but Dober swears by them. I suppose the 200 NAB would be an awesome projectile as well.
