For the 338/06, passing on a charge of 50 grains of 4064, will give an MV of 2500 fps...
with a 200 grain Hornady SP, a 225 grain Hornady SP, and a 250 grain Hornady SP...
and will also have pretty much the same POI at 100 yds...
I kinda like that flexibility.. you can guess what I shoot in my 338/06...
You and Gunner500 about convinced me to go with H-380 in the 338-06. It’s worked well with 180’s to 225’s. I use Varget with the TTSX 160.
I do have 4064, use it in buds .416 Rem.
