Rimmed version of the .308 Winchester, for use in lever-action rifles. .308 Marlin Express: 2006 US 1 [4] R [5] 7.62×48mm 2800 [4] 2514 [4] 1.796 47.7 [10] 0.308 [10] 0.395 [5] 48mm Based upon a slightly shortened .308 Winchester cases with FTX bullets and special powder to approach .308 ballistics from a Marlin lever-action rifle. .308 Norma ...
A 5.56 NATO round fired from a 20 in (510 mm) barrel has a flatter trajectory than a 7.62 NATO round fired from a barrel of equal length, while the 5.56 NATO fired from a 14.5 in (370 mm) barrel has the same trajectory as the 7.62 NATO from a 20 in barrel, as well as the same time of flight.
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.
SMc cartridges were developed in an attempt to produce an efficient cartridge combining low recoil, low heat, and high velocity. [4] The 5 mm/35 SMc has produced velocities in excess of 4,800 ft/s (1,500 m/s) shooting a 30-grain (1.9 g) molybdenum disulfide-coated Berger bullet from a 28-inch (71 cm) Pac-Nor barrel, far higher than its commercial counterpart the .204 Ruger.
The .25-20 Winchester / 6.6x33mmR, or WCF (Winchester center fire), intermediate cartridge was developed around 1895 for the Winchester Model 1892 lever action rifle. It was based on necking down the .32-20 Winchester. In the early 20th century, it was a popular small game and varmint round, developing around 1,460 ft/s with 86-grain bullets ...
Ballistics by the Inch (often called BBTI) was a project to test the performance characteristics of a variety of common handgun calibers/cartridges. The initial testing was done in 2008 and tested the velocity of 13 common handgun cartridges as it related to firearm barrel length.
Barrel length helps determine a specific cartridge's muzzle velocity. A longer barrel typically yields a greater muzzle velocity, while a shorter barrel yields a lower one. The first AR-15 rifles used a barrel length of 20". In the case of the 223 Remington (M193), ammunition loses or gains about 25.7 ft/sec (7.8 m/s) for each inch of barrel ...
This is a graph of a simulation of the 5.56 mm NATO round, being fired from a 20-inch (510 mm) barrel. The horizontal axis represents time, the vertical axis represents pressure (green line), bullet travel (red line), and bullet velocity (light blue line). The values shown at top are peak values
