I built a rifle with 1:20 brux barrel on a 700SA, hankins ignition and modules. How big of a difference in charge should I be doing when working up a load with BH209? I have some arrowhead bullets in 300, 325, and 350gr. I've seen the data from western powders and they stop at 120gr by volume. I'll be weighing them on my reloading scale.
