How to Determine the Rate of Twist in a Rifle Barrel Presented by Larry Potterfield of MidwayUSA
This video demonstrates a practical method for determining the rate of twist in a rifle barrel using simple tools. Larry Potterfield of MidwayUSA explains the importance of matching bullet weight to twist rate for optimal accuracy. The process involves inserting a cleaning rod, marking its position, rotating it one full turn within the rifling, and measuring the distance traveled to calculate the twist rate.
