Lead is a biproduct of brass farming.
I think I picked up about 400-500lbs of brass last year.
I'm seeing brass at about $3/lbs, so I'm at $1200-$1500 for the brass with $33-$50 of lead.
I think of brass farming as exercise, so I try to shoot 1-2 hours and pick up brass for 1-2 hours, so I think it's a good value.
It's better than a gym membership.
It's really easy to pick up the lead though. Shovel + empty bucket of kitty litter and I get 2-5 lbs of lead at the end of a good day, shooting and picking up brass.
I also salvage plastic pistol round trays I use to sort, dry, and organize my .223, .45 and .308 reloads.
