Now that this thread has bubbled back to the top, I see I never posted my final load for my Winchester EW in .264WM. For reasons that I have forgotten, I stopped pursuing a load for the Barnes TSX 120, and switched over to Hammer Bullets. Below is what I finally landed on using a 117 gn Sledge Hammer at 3230 fps. I was able to go up to 3400 fps, but the accuracy wasn't there. The rifle has been skim-bedded, and has a Timney trigger, otherwise it is factory.
