It is somewhat less accurate than the .22 LR[2] and is most suited to hunting small game such as rabbits or prairie dogs.

[3] Shortly before World War II, propellants were developed that greatly increased the effectiveness of the .22 LR.

[citation needed] This increase in power of the smaller round, coupled with its cheaper price and sheer number of rifles already owned in .22 LR, effectively killed the .22 WRF.

.22 WRF ammunition is periodically offered by commercial makers for use in the old guns.

[2] The shorter WRF cartridge may be limited to single shot use in WMR rifles since it may not feed from WMR-length magazines, depending on design.
