The North State Shooters Club in NC will be holding their Spring 2014 midrange weekend March 15-16 on Range 4 at Camp Butner.
A 3x600 may be shot with Service Rifle, Match Rifle, Palma rifle, and any rifle using Iron Sights or at the same time shooters may choose to compete in F-class (different Target shot at the same time). You are on your own for the details of F class. ;)
You fire 3- 20 shot matches with 2 sighters at 600 yards. These matches are an excellent way to test your midrange marksmanship at 600 yards and move releatively quickly. On each day of the weekend there will be a 3x600 followed by a 4 man team match at 600. Usually there is one pit change per 3x600.

I believe that there will be several Appleseed Alumni shooting the matches.
