By 'test lots for ammo test', do you mean something like where they send *you* a bunch of *free* ammo with the conditions that you and whoever else test this ammo in a wide variety of firearms and report back to them averages on said test factors?
If so... hm, sure. Would be a good way to get used to firing my guns; I have ones in 9mm, .45 ACP, and 7.62x51 (308).
