I shoot at a club. it has both indoor and outdoor range. the out door pistol has a fabric covering the ground. I end up sweeping the brass that other people leave .I sweep so I can retrieve my brass. Once in a while I will remove some of the brass that was left behind if it appears new, 9mm and 45acp. The range rules are police your brass. The club does sell the brass to a scrape yard about twice a year or when the trailer is full, the club does make soon money. and it helps to keep membership fees down. I have been a member over Ten Years and the membership is $30 a year and $2 range fee when you shoot.
