Hutton

This whimsically named little noisemaker was cooked up in the 1960s by P.O. Ackley for Bob Hutton of Guns and Ammo magazine's technical department. They were hoping to set a world record for firing .22 caliber bullets at a muzzle velocity of over 5000 fps (1524 m/s).

The round failed to reach the desired velocity, topping out at 4,600 fps. It also had a bit of a problem with spinning bullets so fast they would fly apart before reaching the target.
