Caliber and Twist Rates

 

Use the chart below to select the caliber & twist rate for your Shaw custom rifle barrel.

Twist rates must correspond to the calibers listed.

Please refer to the icons in the caliber list to determine which twist rate can be used in your custom barrel. The number in the box corresponds to the number of inches per complete right-hand twist. For example: 14 would mean that your barrel caliber requires a twist rate of 1 in 14 inches.
