Well, if anyone is interested, it looks like 75-75.5gr H4350 is going to be the ticket. I have a 1.5-5x scope on my 338WM. At 200m, the 75 and 75.5 loads were less than 0.5" apart. Now I just need to go back with a chrono and shoot some groups to get it nailed down. I am hoping to get 3200 fps or so. We will see. . . .
