From Kenny Proulx the ICFRA F-Class Committee Chair
After long discussions with the ICFRA member countries the F-Class Committee has chosen not to modify the chamber rule passed in September 2014 to specifically allow the use of necks with dimensions below SAAMI spec.
During the review process it became clear that many of the commonly available match reamers in use today have neck dimensions that are under SAAMI spec for a variety of reasons, including prolonging the life of components, and that enforcement of this rule would cause unnecessary hardships within the worldwide F-Class community. It is for these reasons that the DCRA FCWC Committee is choosing to limit the technical inspection of F-TR rifle chambers at the 2017 FCWC to maximum SAAMI dimensions for chamber, and minimum dimensions for headspace. The specific testing methods are still being discussed with members of the ICFRA F-Class Committee but they will be announced (and technical drawings made available) as soon as possible.
If you have any questions please let me know, or contact the 2017 FCWC Match Director, Scott Bissett at 2017fcwc@dcra.ca
