Today at a local match a shooter fired insufficient shots in a Virginia Count classifier CM 03-07 Riverdale Standards. Round count for the three string classifier was 20 rounds & shooter only fired 19 shots. On the last string & last target the shooters gun malfunctioned & was unable to finish the COF. As the RO I gave the shooter a mike & procedural for not firing the last shot. But after I read the rule book & couldn't find anywhere that firing insufficent shots in a Virginia Count COF is a procedural, only extra shots & hits incur penalties. Did I make the wrong call? Thanks
