I ride round the ranges near Farnborough and often come across spent blank rounds when the dumb army trainees have not bothered to clear up. I know they are not supposed to leave this stuff. I hate the mess, and can't bear to see good raw materials wasted, so I often pick them up. I always check they are spent, (and they only use blanks in the public areas anyway).
I now have about 6Kg of brass shell cases in a carrier bag in my garage. What to do with them? Will the local scrapyard accept this, or is it worth a few quid at a dealer somewhere? I could just take them to the council dump, but to throw it into a mixed metals bin seems A) Stupid (increasing entropy unnecessarily) or B) May raise some unnecessary alarms.
