4064 is very good, perhaps better for 200s and lighter.
4320 for the win, 225s - 2670 with WW partial sized brass, 23" Hart, 1/2 MOA.
Enjoy.
Don't know if anyone has ever noticed this with the 338/06. But:
50 grains of 4064 with a 200 grain, 225 grain and 250 grain Hornady, each have an MV of 2500 fps?
That is what I commonly load in my Model 70 in 338/06, which was a rebore of a brand new 270 barreled Model 70, that had never been fired.
For the fastest velocity with each of those bullet weights, I use H 380, which is very darn accurate also. Still under SAAMI pressure specs but I load 65 grains with the 200 grain Hornady ( which needs a crimp), 62.5 grains of H 380 with a 225 grain Hornady SP, and 60 grains of H380 with a 250 grain RN ( which I prefer over the SP). Each load is very accurate in my rifle along with the fastest MV out of each bullet weight.
Scope I use on my Model 70 is a Leupold 2 x 7 Shot Gun Scope, with the heavy duplex.
