Re: Sell used brass??
I've done it with berdan primed stuff that used to be left all over an old club range. After about 3 years of sweeping the garbage up there was enough scrap weight there to fund the purchase of a bronze cannon. My dad currently uses it to drive golfballs to the opposite side of the mountain.
Range pickups that I can't use are decapped, cleaned and traded with people for stuff that I can use.
Split necks, loose primer pockets, etc. go into the berdan bucket.
