Definitions for ".22 Hornet"
The .22 Hornet is a low-end varmint and predator centerfire rifle cartridge. It is more powerful than the .22 WMR and the .17 HMR, which in the latter is the result of at least as high a velocity with a bullet twice as heavy. It also drastically differs from all of them in that it is handloadable and reloadable, and thus is much more versatile.
