It has been long-established that the bullet should spin or rotate along the longitudinal axis to c long travel distances while maintaining stability. This spin on a bullet is induced by introducing grooves in the barrel.The twist rate is measured by how many inches of bullet travel down the barrel it takes the rifling to twist the bullet one full turn. This measurement is called the "rate of twist" and is expressed as a ratio, such as 1:7, which means the bullet spins one full rotation in seven inches of barrel travel. The lower the ratio the faster the ...Berger's Twist Rate Calculator provides a predicted stability value called "SG" (for "Gyroscopic Stability").
