A look at the ‘Mad Minute’
While slow, aimed, and deliberate fire was preferred– early SMLEs had magazine cut-off switches to leave the 10-rounds in the magazine as a sort of emergency reserve, forcing users to hand-feed single cartridges into the chamber as they went– the average “Tommy” was trained to deliver rapid-fire when needed, topped off by 5-shot charging clips.
As described in the British musketry regulations of the day, a trained rifleman should be able to lay down between 12 and 15 rounds in a minute, accurately.
In practice, the “Mad Minute” drill on the range became a standard of Commonwealth infantry for almost a half-century, with Australian troops still documented as carrying it out in the 1950s just before the Enfield was replaced with inch-pattern semi-auto FN FALs. Surpassing the 12-15 round minimum mark, some were able to squeeze in over 20 rounds in the same allotted time. One riflery instructor, Sergeant Alfred Snoxall, was credited with being able to deliver an amazing 38 hits on target with his Enfield in a one-minute period.
