The new Sub-Gauge classification does not go into effect until January 1, 2021. The NSCA Executive Council is currently working on the details and the verbiage for the new rule so we can get the programming written for the NSCA database. Until that time, shooters will continue as in the past with the current single classification system.
We will post the new Sub-Gauge classification rule when all the details and the verbiage are ready, prior to the 2021 shoot year.
