Thread: An Interesting Visit to the Range

Greetings again,
You can get some decent velocities from the .308 using AR2206H. 45 grains of that powder with the 150 grain projectile chronographed 2,870 fps the other day in a 24 inch barrel. Book max is 45.5 grains. Even 44 grains chronographed 2,770 fps. In a 20 inch barrel 44 grains of AR2206H chronographed 2,675 fps. 45 grains should give around 2,725 fps even in the 20 inch. Factory loads are often less although I have not fired a factory load for decades.
