25-06 Remington

Originally designed by A. O. Niedner about 1920, this is simply the 30-06 necked down to handle 25-caliber bullets, with no other changes. In 1969, more than half a century later, Remington standardized it as a factory chambering. During the 1900s many of once highly-regarded 25-caliber numbers faded and died – e.g., 25-20 WCF and 25-35 WCF. Conversely, the 25-06 has maintained some, perhaps increasing, degree of popularity since standardization. Thus, it is the only commercial chambering keeping the "quarter-bore" alive and kicking.

With a wide selection of bullets available, the 25-06 is very flexible and is useful for hunting anything up to the size of mule deer or similar species. Although this round has the necessary energy potential, even when loaded with the heaviest normally available bullets, 120 grains, most authorities consider it too light for assurance of sufficient penetration on elk and similar species.

The 25-06 is hard to beat for use at normal ranges on medium-sized game, as well as varmints at longer ranges. Many consider it an ideal choice for pronghorn antelope, caribou and similar species, especially where shots can be rather long.

As with all cartridges with relatively large case capacity, this number is at its best with slow burning propellants. Modern powders provide ballistic potential the likes of which Niedner could only dream. For varminting, most hunters prefer the 87-grain bullet, which provides a superior combination of wind bucking and flat trajectory.
