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.
First experimented with by Wildcatter’s, the 7mm08 is based simply on the .308 Winchester case necked down to 7mm. The original wildcat was utilized by both hunters and target shooters, gaining greater attention in the target shooting arena. Based on popularity, Remington officially adopted the cartridge in 1980 without any changes to the wildcat name or design.
The 7mm08 is often promoted as having a flatter trajectory than the parent .308 while producing less recoil. Unfortunately it is easy to take the above comment out of context. Like the 7mm08, the .308 can be loaded with a range of high BC projectiles which produce desirable trajectories and both are exceptionally useful cartridges. The .308 is somewhat more flexible where a heavy bullet is needed or wanted for use on large animals. With 140 grain hunting bullets the 7mm08 is flatter shooting than the .308 loaded with 150 grain hunting bullets, showing an advantage as a lighter medium game hunting cartridge when utilizing factory loaded ammunition.
One of the greatest traps regarding the 7mm08 has been a range of lightweight rifle designs that produce often intolerable recoil, recoil similar to that of a standard weight .300 Magnum. A large number of hunters are currently ‘enduring’ the recoil of the 7mm08 without knowing that what they are experiencing is unnecessary.
Generally speaking, most current factory 140 grain 7mm08 loads achieve 2800-2840fps from 22†barrels. Killing performance tends to duplicate the 6.5x55. At close ranges, wounding on medium game is broad and kills are very fast. At ranges beyond 150 yards, as velocity falls below 2600fps, kills can be delayed. On tough animals, kills may be so slow as to allow animals to escape great distances.
