There was a large influx of 8×57 JS M98 Mauser rifles into the United States, Australia and New Zealand after the Second World War. Ammunition and brass cartridges were difficult to obtain, and .30-06 brass was in abundance. Gunsmiths began re-chambering the 8×57 JS for the .30-06 cases and the 8mm-06 was born. A .30-06 case may be trimmed, and fire formed to size, but process to resize this brass is time consuming and more difficult than normal.

Load developers were able to achieve much higher performance than the original 8×57 JS with velocities 150 – 200 fps faster. With the larger case capacity and improved propellant, the 8mm-06 is more than capable of hunting large game in North America. The 8mm-06 ability to propel heavy bullets at relatively high speeds has earned it the label as the poor man’s magnum. Today, this versatile caliber has a small and faithful following and should not be underestimated by hunters and shooters.

The 8mm-06 is capable of propelling a .323 dia. 200 grain bullet at 2700 fps with 3260 ft-lbs. of energy.
