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 true answer here is that twist rate must be determined by the bullet chosen, and the velocity that bullet will be launched at.
