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 sharper shoulder and less body taper. Being a rimmed case, it was popular in single shot rifles such as the Martini Cadet and Low Wall Winchester. The caliber is well suited to varmint hunting particularly where minimal pelt damage is required.{{Citation needed|date=May 2017}}
