Vihtavuori Load Data - 243 Winchester

The .243 Winchester cartridge was originally designed as a wildcat by Warren Page who took the .308 Winchester case and necked it down in the early fifties. The objective was to make a light deer rifle which would still have the advantages of the high-velocity .22-calibres for varmint hunting. In 1955 Winchester made it a commercial round. The .243 is a very popular round all over the world for hunting medium sized game, probably due to its flat trajectory and very mild recoil. Surprisingly enough its popularity never reached the same level when it comes to varmint hunting despite the .243” bullets better wind-bucking capabilities.
