The .17 Ackley Bee is a wildcat centerfire rifle cartridge named after its designer, P.O. Ackley, and is a .218 Bee case necked down to .17 caliber with a squarer shoulder and less body taper. Being a rimmed case it was popular with single shot rifles such as the Martini Cadet and Low Wall Winchester[2]. The caliber is well suited to varmint hunting particularly where minimal pelt damage is required.
