I Know, I know, fit is more important then hardness, But....
Came across this ,in some old notes I found in a box reloading estate stuff. The fellow who made these notes (RIP) was from the looks of things, a long distance rifle shooter.
Is there anything to this formula? Could it be useful under certain circumstances?
Optimum BHN = PSI / (1422 x .90)
