As we approach the 100th birthday of the 30-06, we find it to still be the most popular hunting cartridge in the nation. The designation 30-06 comes from its caliber, 30, and its year of creation, 1906. Now, you may be saying wait, isn't the 1903 chambered for 30-06, those years don't match. You would be right, that is because the 30-06 is an improvement on the original 1903 round, the 30-03. In 1906 th 30-03 case was shortened by .07in. and the 30-06 was born. After two world wars and a policing action (Korea), the 30-06 remians the standard to which all other big game rounds are held. In fact the 06 has given birth to numerous other round including 220 swift, 25-06, .270, 35 whelen, and 338-06, plus numerous unrecognized wildcats. Despite all of the new ultra magnums, short magnums, and regular magnums, the 30-06 reigns supreme in the world of big game hunting.
