Looking for a range that has distance out past 300m. Want to start testing distances past what I normally shoot at. I'm located right outside of Philadelphia so I know traveling will probably be necessary. I make monthly trips out toward Huntingdon to Raystowm Lake so I travel a good bit already. Any ranges in that area or closer that are past 300m and preferably available to the public. Want to avoid private ranges so I don't have to fork out more money to be a member of more ranges.
