.17 Hornet [SEP] designer
.17 Hornet
The .17 Hornet is a .17 caliber centerfire rifle cartridge originally offered as a "wildcat cartridge" made by P.O. Ackley in the early 1950s. He created this non-factory (wildcat) offering by simply necking-down the .22 Hornet to .17 caliber and fire-forming the resized cases in his new chamber design. The result was a small quiet cartridge capable of high velocity. Ackley mentions it as one of the most balanced of the .17 cartridges of his time; likely, this is still true.
Calhoon cartridges
Calhoon cartridges are a class of .19 caliber cartridges created by James Calhoon, a firearms designer with an interest in that bore size. Calhoon began working with .19 caliber after his interest was piqued from learning about British sub-caliber rifle trials in the early 1970s. .19 caliber rifles have thicker rifling than .17 and .20 caliber rifles, which helps the barrel stay clean longer and improves barrel life.
