RWVA, formerly Riverside Gun Club, in Ramseur has a service-rifle match on the first Saturday of every month open to non-members. The service rifle competition is from 200-600 yards (500 at RWVA with a reduced target).
The Garand matches at the Eastern Games are all 200 yards.
Forming a squad at the Eastern Games is just a matter of being together in line and asking to be in the same group when you get your assignment card. It's just to let you shoot/pull targets with people you know.
