Thanks Greggors, you need two items. A used .223 or 5.56 case and a wife who is willing to donate her brass sewing stiletto. The sewing stiletto made the perfect pick and fit the case with just the slightest squeeze. I had to trim the pick a little shorter and formed the "bullet" head with a grinder, some filing, and fine sandpaper. The shell was free from picking up brass at my range, the pick was a little more costly to replace, about $15, so I really haven't ventured into making many more.
