We have a "sort of" agreement with a local airgun club, we give their members cheap membership to also use our range and we get their old pellets from the catchers. A few of our members also regularly rake our range sand for spent full- bore cast ammo and lead ball from the BP shooters. This is then separated and shared out for re-smelting, the air pellets mixed with the soft lead from the BP guns for new round ball, and the cast full- bore for remoulding as full bore ammo. The members who use this say the stuff shoots fine, with no problems to the guns etc and a nice saving in ammo, certainly the recycled .357 ammo works well for me, and is a real saving.
We also recycle used brass, mainly .22, as most of our full-bore shooters reload their own ammo. We only use a fairly small bin for cases, but it usually gets us about £40 from the scrap metal guy, which we use to pay for the petrol for the range lawn mower and put the rest into the target repair kitty.
