Freedom Munitions has a program where you can send in expended brass. They give you a certain amount of monetary credit per pound of brass. I haven't done it, but I have pondered it. I have also thought about this....by the time you get through boxing up the brass, pay for the shipping, ordering the new ammo and paying for it, and then paying for the shipping on the new ammo as well as state sales tax...is it even worth messing with? Do you really end up saving much of anything? Anyone out there do it? (If you're in Idaho or Texas you have to pay sales tax.)
