I did not read the article so I must ask, is the author suggesting that the bullets be serial numbered or the cases or both?
I shoot my serial numbered bullets at the range but pick up my cases, with serial numbers, and take them home. I then re-load them with my own cast bullets (w/o serial numbers) and head for the range again. This time I pick up some of my neighbor's empty cases that were "registered" to him and re-load them. Now who, by all that's Holy and half that ain't, is going to know where any of this stuff came from if I went bad and plinked somebody?
