I don't know if you're interested in shooting the high B.C. 162 and 168 grain bullets from Hornady and Berger but if you are here is a load which works great in my 26" 280AI.

162 Amax
64gr Magpro
Nosler brass
WLR

This load is hot but it exhibits no pressure signs in my rifle (Accurate Powder lists 65gr Magpro as max)
This load chronos 3050 fps 15' from the muzzle.
Excellent accuracy.
QL shows pressure in the 62-63K range.

The Chosin Few November to December 1950, Korea.
I'm not one of the Chosin Few but no more remarkable group of Americans ever existed.
