Willing to donate? This would be my first course of action.
Any of this that you still see as being good (I have shot some 10+ old ammo without issue) I'm sure there are a number of places that could use it as a donation. Here in WI we have Learn to Hunt Programs for Turkey (and other species) don't know if your state runs such a program, or maybe a local sportsman's club youth program.
