Using a scientific method of how many fit into a .410 shell box (2.5 not 3"). I have determined within an acceptable margin of error that I have about 550 pieces of mixed head stamp 40 S&W brass. Some are chrome most are brass. These are once fired range pickups after our local LEO qualification day at the range. $30 shipped in a flat rate priority box. Will trade for 35 Whelen brass or bullets.
First I'll take it wins.
