Miller twist rule is a mathematical formula derived by American physical chemist and historian of science Donald G. Miller (1927–2012) to determine the rate of twist to apply to a given bullet to provide optimum stability using a rifled barrel. Miller suggests that, while Greenhill's formula works well, there are better and more precise methods for determining the proper twist rate that are no more difficult to compute.
