While the target shooter has special ammunition available, the hunter of small game and pests has not been left out. The 22 LR high-speed solid uses a 40-grain bullet that has a muzzle velocity of approximately 1,235 ft/sec while the 36- to 38-grain hollow-points are about 40 to 50 ft/sec faster. Other specialty loads will be described elsewhere in this chapter and in several later chapters. The 22 LR is in many ways the most useful cartridge in existence. A rifle or handgun chambered for this round can be used for many purposes.

22 Winchester Rim Fire (WRF)

In 1890, Winchester introduced a pump-action rifle that is quite possibly the most famous 22 pump rifle ever produced. Designated as the Model 1890 (also known as the Model 90 and some rifles are so marked), the rifle chambered either the 22 Short or a new rimfire cartridge known as the 22 Winchester Rim Fire (WRF) or Winchester Special. The 45-grain flat-point bullet was offered in several loads, some of which gave a velocity as high as 1,400 ft/sec. The original load consisted of 7.5 grains of black powder and it had a muzzle velocity of 1,100 to 1,200 ft/sec. Remington used essentially the same case loaded with a round-nose bullet as the 22 Remington Special. The 22 WRF was popular for many years, but because it offered little advantage over the 22 LR, its popularity declined as the 22 LR became more highly developed.
