The .30-06 Springfield cartridge case can hold 68.2 grains and has a volume of 4.42 millilitres (0.270 in 3). The exterior shape of the case was designed to promote reliable case feeding and extraction in bolt-action rifles and machine guns alike, under extreme conditions.

(or 6.5mm/06) - necked down to accept a 6.5 mm bullet - The 6.5-06 offers ballistic performance between the commercialized 25-06 Remington and 270 Winchester with distinct advantages over both in particular long-range applications through a wide selection of bullets with high ballistic coefficients producing better extended range performance.
Loaded with lighter bullets, the .260 Remington can be used as an effective varmint or a small predator hunting cartridge for use against such species as marmots, woodchucks, bobcats and coyotes. Bullets chosen for these species should be designed to open rapidly unless harvesting of the pelt is the objective.
The .25-06 Remington was a wildcat cartridge for nearly half a century before being standardized by Remington in 1969. Its design was based on the .30-06 Springfield cartridge necked-down (case opening made narrower) to .257 caliber keeping a similar cartridge length of its parent case, thus being chambered in standard-length actions.
Source (s): Federal Cartridge Co. ballistics page, 175gr. The 7mm-08 Remington is a rifle cartridge that is almost a direct copy of a wildcat cartridge developed around 1958 known as the 7mm/308. As these names would suggest, it is the .308 Winchester case necked down to accept 7 mm (.284) bullets with a small increase in case length.
Ballistic coefficient. A selection of bullets with different shapes, and hence, different ballistic coefficients. In ballistics, the ballistic coefficient (BC, Cb) of a body is a measure of its ability to overcome air resistance in flight. [1] It is inversely proportional to the negative acceleration: a high number indicates a low negative ...
The .30 Remington AR is a cartridge created in 2008 by Remington Arms to fill a perceived gap in performance on large game between the .223 Remington and larger cartridges such as the .308 Winchester. [1] The design of the cartridge is considered a joint effort between companies under the "Freedom Group" name through a private equity firm [1 ...
External ballistics. This schlieren image of a bullet travelling in free-flight demonstrates the air-pressure dynamics surrounding the bullet. External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin ...
