What is the value of used brass? I have been collecting my brass for awhile (9mm, .45, .380) and have it in jugs in my garage. A friend who reloads said he'd trade me ammo for the brass. What is the equal trade value for lets say a 50 round box of 9mm range ammo? The brass I have still has the primers and hasn't been tumbled. I just pick it up after shooting and throw it in the jug. Thanks in advance. I'm going to check in a couple of forums to see what everyone's opinions are.
