History of the.307 Winchester Cartridge:The 307 Winchester was introduced in 1982 as a “rimmed” version of the 308 Winchester or the 7.62x52mm NATO rimless cartridges.It was designated 307 Winchester to avoid confusion with the rimless 308 Winchester (7.62x51mm NATO).As in many of European Calibers, Winchester was hoping a rimmed version would be better in a lever action, bolt action and breech loading rifles, however the volume was not worth the production, and it is now also obsolete, however sometimes a special run is produced.Note the differences in the 307 Winchester vs. 308 Winchester in the below picture.
