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. [1]
Early production rifles had a 1:12 twist rate and post-2014 rifles have the 1:9 twist rate. [3] The CZ 527 Varmint in .223 has muzzle velocities for standard-load 45-grain (2.9 g) ammunition of around 3,500 feet per second (1,100 m/s). The 1:9 barrel twist in the Varmint Kevlar reduces muzzle velocities by about 1.5%.
