Lineage
History
Winchester introduced the .22 WRF in 1890 alongside the Model 1890 slide-action rifle — the first successful pump-action .22 and a staple of shooting galleries across America. The cartridge uses a slightly larger case diameter than the .22 LR family, making them incompatible; a firearm chambered in .22 WRF cannot safely fire .22 LR. Remington chambered their Model 12 pump rifle in .22 WRF as well, calling the cartridge the '.22 Remington Special.' The introduction of the .22 WMR in 1959 largely supplanted it in the marketplace, but Winchester and CCI continued producing it for the large installed base of Model 1890 and Model 12 rifles. It remains available today — a 135-year-old cartridge still in active production.
