What is the difference between 22 LR and Hornet?

The .22 Long Rifle (22 LR) and the .22 Hornet are both rimfire cartridges, but there are some key differences between them.

* Bullet diameter: The .22 LR has a bullet diameter of .224 inches, while the .22 Hornet has a bullet diameter of .223 inches. This slight difference in bullet diameter means that .22 LR ammunition cannot be used in a .22 Hornet rifle, and vice versa.

* Case length: The .22 LR has a case length of .635 inches, while the .22 Hornet has a case length of .920 inches. This difference in case length means that .22 LR ammunition cannot be used in a .22 Hornet rifle, and vice versa.

* Powder charge: The .22 LR has a powder charge of about 2 grains, while the .22 Hornet has a powder charge of about 5 grains. This difference in powder charge gives the .22 Hornet a higher muzzle velocity and more energy than the .22 LR.

* Accuracy: The .22 LR is a very accurate cartridge, and it is often used for target shooting and plinking. The .22 Hornet is also an accurate cartridge, but it is not quite as accurate as the .22 LR.

In general, the .22 LR is a better choice for target shooting and plinking, while the .22 Hornet is a better choice for hunting small game.
