.22 Winchester Centerfire (.22 WCF) / 5.8x35mmR is a small centerfire intermediate cartridge introduced in 1885 for use in the Winchester Model 1885 single-shot rifle. Factory manufacture of ammunition was discontinued in 1936. The .22 WCF was loaded with a 45 grain bullet with a muzzle velocity of about 1550 feet per second, similar to the performance of the .22 Winchester Rimfire (.22 WRF) designed in 1890.{{cite web|last=Hawks|first=Chuck|title=The .22 Centerfire Varmint Cartridges|url=http://www.chuckhawks.com/22caliber_cartridges.htm|publisher=chuckhawks.com|accessdate=31 October 2013}}{{cite web|title=Centerfire Rifle|url=http://www.winchester.com/products/rifle-ammunition/Pages/default.aspx|publisher=winchester.com|accessdate=31 October 2013|archive-url=https://web.archive.org/web/20130911075524/http://www.winchester.com/Products/rifle-ammunition/Pages/default.aspx|archive-date=2013-09-11|url-status=dead}}{{cite web|title=Latitude and Longitude|url=http://www.satsig.net/maps/lat-long-finder.htm|publisher=satsig.net|accessdate=31 October 2013}}{{cite web|title=.22 Winchester Centerfire (.22 WCF) Reloading Data|url=http://www.loaddata.com/members/search_detail.cfm?MetallicID=2172|publisher=loaddata.com|accessdate=31 October 2013|archive-url=https://web.archive.org/web/20131102212430/http://www.loaddata.com/members/search_detail.cfm?MetallicID=2172|archive-date=2013-11-02|url-status=dead}}

Experimentation with the .22 WCF among civilian wildcatters and the U.S. military at Springfield Armory in the 1920s led to the development of the .22 Hornet cartridge.Barnes, Frank C., Cartridges of the World, DBI Books 8th ed. 1997, p. 16. {{ISBN|0-87349-178-5}}.
