The .17 Hornet, also known as the .17 Ackley Hornet, is a .17 caliber rifle wildcat cartridge originally made by P.O. Ackley in the early 1950s. The cartridge was created by simply necking-down the .22 Hornet to .17 caliber. The result was a small case with relatively little noise capable of high velocity.
Ackley mentions it as one of the most balanced of the .17 cartridges of his time. [1]
This cartridge is now available as a factory loading, the 17 Hornet from Hornady uses a 20grain "Superformace" v-max projectile at a published velocity of 3650fps. http://www.hornady.com/store/17-hornet-20-gr-V-MAX-Superformance-Varmint/
