For full power loads, about 56 grs. of IMR 4451 shot the best with the Barnes TTSX, and Sierra's 120 gr. bullets. But the best accuracy came with 47.5 grs. of H4895.
BTW, with Barnes TSX/TTSX there is no need to go to the 139/140 gr. stuff. They shoot very flat, penetrate, and kill very well. E

I'm glad you mentioned the Barnes, I plan on trying the 120gr tsx
