I am in and here is my $.02 worth. As issued millsurp: any military rifle of 1955 or earlier vintage with original reciever,barrel,sights,trigger, stocks may be cut down but no replacement sporters. (This will give all the cut down millsurps a chance to play). 100 yards or meters will work. Ammo: what ever you want to shoot. Have one target that is shot prone, standing or sitting. Have this target scored for value such as bulleye. If you want to shoot off bench have this target scored for smallest group.
