.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.
