Range #1 is a position rifle range with berms from 50yds to 300 yds.  By "position" range, it is meant that you can shoot from any position you wish, including offhand, sitting, prone, or benchrest.   However, you must make sure that no person is forward of the rear-most firing line.  In other words, you cannot have some people shooting prone infront of the benches, while other people are shooting from the bench.  Also, be sure to confirm that your rifle has been sighted in and scopes zeroed before firing at distances over 50 yds
