Had to look up the British meaning of "Mad Minute". Found this on Wikipedia
..
Mad minute was a pre-World War I term used by British riflemen during training to describe scoring 15 hits onto a 12" round target at 300 yd within one minute using a bolt-action rifle (usually a Lee-Enfield or Lee-Metford rifle). It was not uncommon during the First World War for riflemen to greatly exceed this score. Many riflemen could average 30+ shots, while the record, set in 1914 by Sergeant Instructor Alfred Snoxall was 38 hits.[1]
In my day, in Vietnam, a Mad Minute was just something done on outpost firebases in the middle of nowhere in the evening to let guys see if their firearms were still working....or at least that's what I made of it. No sense to it otherwise. There were no targets ...officially.. and nobody counted rounds or hits, although it lasted, more or less, about a minute.
