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.[3] 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 created, 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 diameter. Since then newer slower-burning powders have become available and have really improved performance of this cartridge.[4]
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
SAAMI pressure limit for the .25-06 is 63,000 PSI.
Uses
The .25-06 is the most popular and arguably the most useful of the .25 caliber cartridges. It is an ideal round for deer and antelope, but will cover game ranging from prairie dogs to elk. However, if one chooses to use the .25-06 for large game, one must remember that .257 in (6.35 mm) bullets are of fairly light construction and will not penetrate bone like a .284 or .308 in (7.21 mm or 7.82 mm, known as 7 mm or 7.62 mm caliber) bullet will, and therefore shot placement is paramount. The cartridge has it's best advantage when used with heavy bullets.[3] The .25-06 cartridge has a flat trajectory that is well suited to open plains hunting where long shots are the norm.
The .25-06 is many a hunter's most favored firearm for hunting coyote. It provides quick clean kills with minimal recoil, a flat trajectory, and when used with appropriate bullets, minimal hide damage.
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.
