The formula for Miller stability is. SG = 30 m/ (t^2 * d^3 * L (1 + L^2)) Where: m is the bullet mass in grains. t is the rifling twist rate in calibers per turn. d is the diameter of the bullet in inches. L is the length of the bullet in calibers. This formula assumes the muzzle velocity is very close to 2800 fps.Ballistics calculations and formulas for small arms. Recoil.
