Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load ...
The .243 Winchester has also been found to shoot flatter and more accurately than the 7mm-08 Remington out to 500 yards, with less recoil yet also less terminal energy. [11] (Left to right) .223 Rem, .243 Win, .308 Win. The recoil has been measured to be so light that it "can be shot by anyone that can handle a rifle."
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.
The .284 Winchester case is very similar to the .308, however, the .284 case has a body diameter of 0.500", and the .308 case has a body diameter of 0.471". Both share an identical head/rim. The 450B is limited to 35,000-psi, which is more common in pistols, and lower than similarly sized rifle cartridges.
The 6mm Advanced Rifle Cartridge (6×38mm), or 6mm ARC for short, is a 6 mm (.243) caliber intermediate rifle cartridge introduced by Hornady in 2020, as a low-recoil, high-accuracy long-range cartridge, designed for use in the M16 platform at request of a specialized group within the U.S. DoD for its multipurpose combat rifle program.
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 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 ...
The .243 Winchester Super Short Magnum or .243 WSSM is a rifle cartridge introduced in 2003. It uses a .300 WSM (Winchester Short Magnum) case shortened and necked down to accept a .243in/6mm diameter bullet, and is a high velocity round based on ballistics design philosophies that are intended to produce a high level of efficiency.
