The 25-06 Remington takes its design from a marriage of the quarter-inch bore and Charles Newton’s .30-60 Springfield cartridge. This necked-down version of the .30-60 has existed as a wildcat cartridge since its inception around 1920, introduced by the A. O. Nidner. The cartridge came at a time when the conditions encouraged independent gunmen to experiment with it. This, and the release of the IMR 4350 in 1940, which greatly improved the performance of the .25-06 case, increased the popularity of the wild-cat cartridge. Thus, the natural occurrence was its commercialization which occurred in the late 1960s by the Remington Arms company.
A factory load of 100 to 117 grains can be easily propelled at a muzzle velocity of 3200 fps, generating energy levels up to 2500 ft-lbs. The .25-06 is a flat-shooter that is effective over 350 yards (with nothing more than a 5-inch difference above or below your aiming point) as well as 50 yards. The flatness minimizes range-estimation errors and provides quality shot placement, making it a fine cartridge for hunting anything from coyotes to large deer.
Lighter weight bullets are used in this cartridge, giving it lower recoil than its counterpart, the .30-60, in a similar weight rifle. This kick is bearable, but shoot for a long time at a stretch and the recoil begins to turn unpleasant.
If you have got a bolt-action or a single-shot rifle, you will notice that most often than not it offers, as its standard chamber,.25-06. It still remains a top experimental cartridge, which can be hand loaded (or reloaded) to the users' satisfaction.
The .260 Remington Ammo started its life as a wildcat cartridge called the 6.5-08 and finally got released as a commercial cartridge by Remington even though they were not the first to standardize the cartridge. It has the .308 Winchester as its parent case, and this is necked down to make it capable of accepting a .264 caliber bullet with no change to its case.
The .260 Remington Ammo has a slightly shorter overall length in comparison to the 6.5 Creedmoor round. However, in terms of velocity and accuracy in hits, it performs almost the same as the 6.5 Creedmoor round. In addition, the bullets of the .260 Remington Ammo have good sectional density or penetrating ability.
The .260 Remington has a neck diameter of .2969inches and a shoulder diameter of 11.53mm. Additionally, it has a rim diameter of 12.01mm and a rim thickness of 1.37mm. It also has a max pressure of 60,000psi. And a primer type of a large rifle.
Loaded with lighter bullets, the .260 Remington can be used as a practical varmint or a small predator hunting cartridge against such species as marmots, woodchucks, bobcats, and coyotes.
The .260 Remington is a tactical and target shooting ammo. It is metallic and is effective on antelopes, sheep, and goats. It is also efficient in taking down larger games such as elk and moose. Loaded with bullets weighing from 120gr (7.8g) to 140gr (9.1g), the .260 Remington Ammo can be loaded to higher pressure levels.
