[5] Niedner Arms Corporation retained the 17° 30′ .30-06 shoulder chambering .25 caliber barrels rifled with one twist in 12 inches (300 mm).

[7] Availability of DuPont's Improved Military Rifle (IMR) powders encouraged commercial release of the .257 Roberts using the 57 mm Mauser case in 1934.

[8] Release of IMR 4350 in 1940 and availability of surplus 4831 powder salvaged from Oerlikon 20 mm cannon cartridges after World War II greatly improved performance of the full-length .25-06 case.

The .25-06 is generally considered to be a good round for medium-sized game such as deer and antelope because of its combination of substantial kinetic energy and moderate recoil.

Bullets of different weights and construction make the .25-06 Remington a fine alternative for hunting species ranging from prairie dogs and coyotes to mid-sized deer and sheep.
