My 26" 308 shoots that bullet sub moa beyond 750y with 44g of H4895, with 2770fps. Seated about 0.015 from lands.
Hodgdon book max is 43.5 from memory so work up.
I should have said this at the time, but these loads are at 2.91" as the rifle is a single shot. 1-12 twist.
I also tried Varget at various charge weights but for me H4895 gave the better accuracy, by a bee's pizzle.
