In the old USMC windage formula they use a math constant of 15 to 500 yards, then it changes for distance. I have seen different numbers for different loadings of 30 caliber ammo.
Any way, the question I have is what is the formula to find this constant number? I shoot the 30-06, 7.62x54, and 308 so this could be quite helpful info since this formula works for the 30 caliber.
