Friend brought over a whole cooler full of ammo that was submerged in river water for over a week. 38, 357, 40, 223, 243, 257 Roberts, all manner of 12 guage and 410, thousands of 22's. All of it factory ammo. Is there any feasable way to break down shotshells, or just cut the hulls to reclaim the shot? Anyone ever find copper plated 22 bullets worth smelting, or just scrap them? This project is going to probably take me weeks, if not months. Any time saving tips would be greatly appreciated. Thanks.
