As for disposal you should have allowed for more than one response. I throw away shells from skeet and trap shooting since this type of ammunition is so cheap at Walmart it is not worth the effort of reloading them. When hunting with my 10 guage Remington SP-10 auto-loading shotgun I do try to pick the shells up for reloading since 10 guage ammunition is expensive. However, in this case, rather than a device that merely picks up the shells, what I really need is something that can find them. The SP-10 ejects the shells a fair distance and in tall grass or reeds it can be very hard to find them.
