.30-06 US / 7.62×63
This cartridge was born in 1906 as an evolution of the short-living .30-03 cartridge, that was originally adopted by US Army in 1903 with round-nose bullet. The .30 caliber M1906 cartridge, today universally known as .30-06, had slightly different case and, more important, it was loaded with pointed bullet. It served with US armed forces through both world wars and Korean war, and was gradually replaced in service with 7.62×51 NATO since 1957. It is still extremely popular worldwide as a hunting and target round, with new weapons (mostly bolt-action and semi-automatic rifles) and ammnuition being manufactured in many countries and in many styles.
