The .22 WMR was created by lengthening the case of the .22 Winchester Rimfire (.22 WRF). The .22 WRF was developed specifically for the Browning-designed Winchester Model 1890 slide-action rifle and was loaded with a .224-inch, inside-lubricated lead bullet weighing 45 grains. Muzzle velocity was 1,450 fps. A Super Speed loading with a Kopperclad 40-grain hollowpoint bullet at 1,475 fps came a bit later. Respective energy ratings at the muzzle and at 100 yards were 210 and 123 foot-pounds (ft-lbs). The cartridge was also loaded by Remington with a 45grain bullet at 1,450 fps, but the company called it the .22 Remington Special. At the time, the 40-grain bullet in high-velocity .22 Long Rifle ammunition was given energy ratings of 158 and 97 ft-lbs at the muzzle and at 100 yards. In addition to delivering a tad more punch to the target, the 45-grain bullet at higher velocity from the .22 WRF offered more penetration. The .22 WRF is still alive and well at Winchester, where it is presently loaded with a 45-grain, Lubaloy-coated, flatnose bullet at 1,300 fps.

Remington's Model 722 and .222 Cartridge
It's easy enough to define what a varmint is, those pesky critters that tear up pastures, flower beds and all kinds of expensive crops people need for various reasons - most importantly, to make a living and/or something with which to feed themselves.
