Lol. That is the same old tired line. Exactly how many people get all their 9mm brass for FREE? Very few unless they are picking it up on the range. Oops. I thought you guys hated picking up brass. Without exception every 9major shooter I know pays roughly $30/k for brass. None of them pick up a single piece at a match. So they pay .03 per shot in just brass. I pick up 90% of my brass at matches and load them until they split, at least 15-20 times. You do the math.
Not to mention all the blown case heads and time spend sorting brass by head stamp, dealing with crimps, stepped brass, yada yada yada. You can have all that 9mm brass.
