.22 Hornet

The .22 Hornet or 5.6×36mmR Hornet is a varminting, small-game hunting, survival and competition centerfire rifle cartridge commercially introduced in 1930. It is considerably more powerful than either the .22 WMR and the .17 HMR rimfire cartridges, achieving a higher velocity with a bullet twice the weight of that used in the .17 HMR. The Hornet also differs significantly from these in that being a centerfire cartridge makes it reloadable, and thus more versatile. It was also the smallest commercially available .22 caliber centerfire cartridge until the introduction of the FN 5.7×28mm. The .22 Hornet should not be confused with the 5.6x35mmR Vierling. As per C.I.P., the Hornet case has a longer shoulder length, case length and thicker rim than the Vierling. This makes it very difficult to chamber the higher pressure Hornet cartridge in a Vierling rifle. The .22 Hornet fills the gap between such popular varmint/predator cartridges as the .22 WMR and the .223 Remington. In regard to muzzle velocity, muzzle energy and noise, it is well suited to vermin and predator control in relatively built-up areas.
