Introduced in 1955, the .243 Winchester cartridge is reckoned to be the most popular 6mm round in use today for hunting medium-sized game and for target shooting. Designed by necking-down a .308 Win case to take a .243in (6.17mm) bullet, the round is capable of achieving high velocities thanks to the large powder capacity of its case and the fact it shoots flat out to most ranges at which one might expect to engage live quarry. It is not surprising that BASC has estimated that nearly 14% of all rifles held on certificate in Britain — around 60,000 — are chambered for the .243 Win cartridge.
