Saw an episode of one of those shooting competition reality shows where the contestants squared off shooting Tommy guns with either 50 or 100 round drum magazines. The goal was to completely obliterate a paper target (shoot out all the red) at about 30' in the standing position. In very short order each contestant, who were experienced shooters went from controlled bursts to spraying and praying.
They hit everything else around their targets but neither completed the goal. They sure had a lot of fun though and went through a ton of bullets.
Always like your posts Gunny but that slaughterbot post has kept me up at night
