The .25-06 Remington had been a wildcat cartridge for about 35 years before being standardized by Remington in 1969. It is based on the .30-06 Springfield cartridge necked-down (case opening made narrower) to .257 inch caliber with no other changes. Nominal bullet diameter is 0.257 in (6.5278 mm) and bullet weights range from 75 to 122 grains (4.9 to 7.9 g).

Performance

When it was first standardized, handloaders commonly used World War II surplus gunpowder. Burn rates of the available powders at that time were not well-suited to such a large case with a relatively small bore. Since then newer, slower-burning powders have become available and have greatly improved performance of this cartridge.[3]

The cartridge is capable of propelling a 117 grain (7.6 g) bullet at up to 3200 feet per second (980 m/s) and energy levels up to ~2,500 ft·lbf. Bullets lighter than 75 grains are available in .257" caliber, but were designed for the smaller .25-20 Winchester and .25-35 Winchester cartridges and are too lightly constructed for the high velocities of the .25-06.

The cartridge has mild recoil, somewhat below the .270 Winchester but more than the .243 Winchester and .257 Roberts. Shooters who are recoil sensitive will find the recoil from the 25-06 bearable, but not pleasant enough to shoot all day long. This cartridge is nearly as powerful as the .257 Weatherby Magnum, usually running 100-150 ft/s. slower with a given bullet weight.

SAAMI pressure limit for the .25-06 is 63,000 PSI.

Uses

.25-caliber bullets typically have high ballistic coefficients without being heavy. This characteristic, when combined with the large case capacity of its parent .30-06 case, allows relatively high muzzle velocities without heavy recoil. The combination of high ballistic coefficients with high muzzle velocities give the .25-06 a very flat trajectory as well as retaining kinetic energy down-range.

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. The addition of a flat trajectory makes it particularly popular in plains states where the open fields can require longer-range shots on game, as this flatness tends to minimize range-estimation errors by the hunter. However bullet types and weights are loaded that allow the .25-06 to be used for taking game ranging from small animals like prairie dogs and coyotes to heavier elk. These bullets range from lightly-constructed 75-grain bullets with muzzle velocities in the 3,700 ft/s (1,130 m/s) range to heavily-made 120-grain bullets with muzzle velocities in the 3,000ft/s (915 m/s) range.

Most manufacturers of bolt action or single-shot rifles offer the .25-06 as a standard chambering and factory loaded ammunition is available from Remington, Winchester, Federal Cartridge and most other major manufacturers.
