The .308 Winchester has a 3.64 mL (56 gr H 2 O) cartridge case capacity. [9] 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. .308 Winchester maximum C.I.P. cartridge dimensions. All dimensions in millimeters (mm) and inches.
From left to right 9.3×62mm, .30-06 Springfield, 8mm Mauser, 6.5×55mm and .308 Winchester cartridges. Norma Oryx Soft Point cartridges in plastic holder (producer Norma Precision AB, Sweden) The 9.3×62mm (also known as 9.3×62mm Mauser ) is a rimless, bottlenecked rifle cartridge designed in 1905 by German gunmaker Otto Bock.
The 7mm-08 with 139-140 grain loads does well against some 150-grain .308 Win. loads, providing good energy levels. One example is the Remington 7mm-08 140 PSP (1490 fpe at 300 yards) compared with the Remington 308 150 grain PSP (1344 fpe at 300 yards). [14] The 7mm-08 invites a ballistic comparison with the veteran, highly esteemed 7×57mm ...
Lighter bullets of 150–180 grains can be driven to velocities of 3,300-3,500 ft/sec, putting it in the same class as the larger-cased .300 Remington Ultra Magnum; Such loads offer a very flat trajectory, making it an optimal choice for deer- and elk-sized game at very long range.
In ballistics, the ballistic coefficient (BC, C b) 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 acceleration—the drag on the body is small in proportion to its mass.
The dimensions of .308 Winchester are almost the same as 7.62×51mm NATO. The chamber of the former has a marginally shorter headspace and thinner case walls than the latter due to changed specifications between 1952 and 1954. This allows 7.62×51mm NATO ammunition to feed reliably in rifles chambered for .308 Winchester, but can cause .308 ...
Galileo established the principle of compound motion in 1638, [6] using the principle to derive the parabolic form of the ballistic trajectory. [7] Ballistics was put on a solid scientific and mathematical basis by Isaac Newton, with the publication of Philosophiæ Naturalis Principia Mathematica in 1687. This gave mathematical laws of motion ...
.308 Winchester: the commercial name of a centerfire cartridge based on the military 7.62×51 mm NATO round. Two years prior to the NATO adoption of the 7.62×51 mm NATO T65 in 1954, Winchester (a subsidiary of the Olin Corporation) branded the round and introduced it to the commercial hunting market as the .308 Winchester.
