5.6Chronograph and Power Factors

One or more official match chronographs are used to assist in the determination of the power factor of every competitor’s ammunition. In the absence of official match chronograph(s), the power factor declared by a competitor cannot be challenged.

The power factor rating to enable a competitor’s scores to be included in match results is called “Minor”. Some Divisions offer a higher power factor rating called “Major”, which enables competitors to earn more points for peripheral shots on scoring cardboard targets.

The power factor floor for Minor rating and the power factor floor for Major rating, if available, and other specific requirements applicable to each Division are stipulated in Appendix D.

The associated values awarded for Minor and Major scoring hits are illustrated in Appendix B.

The method used to determine power factor and the procedures used at the Chronograph Station are stipulated in Appendix C2.
