With 150's, I would start with W760 (I have not tried IMR4064, but it's been mentioned alot for this bullet weight).
with 165/168s, I would start with VV-N550 and H4350
With 180's, I would start with H4350 and IMR4831.
The most consistently performing powder in my 300 WSM has been H4350 - If I had to stick with only one powder, this would be it. I have personally tried RL17, RL19, H4350, IMR4831, VV-N550, VV-N560, W760 and IMR4350. However, my experience is almost entirely with Barnes bullets (TSXs, TTSXs, and MRXs). I am only now starting to "play" with other bullets.
NOTE: W760 = H414 (same powder)
