The .22 Long Rifle, often abbreviated as .22 LR, is a popular rimfire cartridge primarily used for target shooting, small game hunting, and training. It was introduced in 1887 and has since become one of the most widely used cartridges in the world due to its low recoil, affordability, and availability. This cartridge is compatible with a variety of firearms, including rifles and handguns. The .22 LR typically features a bullet weight of 30 to 40 grains and a muzzle velocity of around 1,000 to 1,200 feet per second, making it suitable for beginners and experienced shooters alike.
