The .25-35 Winchester, or WCF (Winchester Center Fire) was introduced in 1895 by Winchester for the Winchester Model 1894 lever action rifle. The case was based on the .30-30 cartridge.

Significantly more powerful than the .25-20 Winchester the .25-35 WCF can be used to hunt small deer at 200 yards and medium-sized deer at 100 yards, however, some consider it better suited to small predators such as coyotes instead. It was a popular round in the Winchester Model 1885 High Wall single-shot rifle. No production rifles had been made in .25-35 WCF since the 1940s until 2005 when Winchester resumed chambering their Model 94 rifles in this cartridge. Winchester ammunition has kept the cartridge in production in the U.S.A.

The 6.5×52mmR is a European cartridge that is a close variant of the .25-35 Winchester. It should not be considered identical to the .25-35 Winchester and is not treated as such by the Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives (CIP), which has released separate specifications for each cartridge. The 6.5×52mmR has its origins in Germany and was introduced by RWS and is chambered in many drilling and single-shot rifles. Any interchangeability between the two cartridges is solely dependent on individual chamber tolerances and should not be assumed.
