Introduced in the Winchester M1890 slide rifle, it had a flat-nose slug, and is identical to the .22 Remington Special (which differed only in having a roundnosed slug).[1] It uses a flat-based, inside-lubricated bullet, which differs from the outside-lube slug of the .22 Short, Long, LR, and Extra Long rounds.[1]
When introduced, the .22WRF "was the first notable improvement in the killing power" over the .22LR,[2] and was able to kill cleaner at up to 75 yd (70 m). It is somewhat less accurate than the .22LR.[1] and is most suited to hunting small game, such as rabbits or prairie dogs.[2]
A variety of Winchester, Remington, and Stevens single-shots and repeater rifles were offered from 1890 onward, but new rifles are not made for this cartridge. .22 WRF ammunition is periodically offered by commercial makers for use in the old guns.[1] It can be fired in any rifle chambered for the more powerful .22 WMR.[1]
