The original .357 Magnum load was a 158 gr (10.2 g) bullet with an advertised muzzle velocity of 1,525 ft/s (465 m/s) and muzzle energy of 816 ft⋅lbf (1,106 J). (Muzzle velocity was taken using a large frame revolver with a fairly long barrel of 8.75 in (222 mm)) Most of today's SAAMI conform loads are fairly mild when compared to the ...
used to load the 173-grain (11.2 g) .30-06 Springfield M1 bullet; sold as military surplus by DCM [15] 1204 1925 1935 thin & short replaced by 4227 [15] 3031 1934 standard replaced 17 1/2; [18] for mid-range loads and medium sporting and military cartridges like the .257 Roberts, .30-30 and .348 Winchester [11] 4064 1935 standard
Data values are the highest found for the cartridge, and might not occur in the same load (e.g. the highest muzzle energy might not be in the same load as the highest muzzle velocity, since the bullet weights can differ between loads).
Components of a modern bottleneck rifle cartridge. Top-to-bottom: Copper-jacketed bullet, smokeless powder granules, rimless brass case, Boxer primer.. Handloading, or reloading, is the practice of making firearm cartridges by manually assembling the individual components (metallic/polymer case, primer, propellant and projectile), rather than purchasing mass-assembled, factory-loaded ...
The .357 Maximum, formally known as the .357 Remington Maximum or the .357 Max, is a super magnum handgun cartridge originally developed by Elgin Gates as the wildcat .357 SuperMag. [1] The .357 Maximum was introduced into commercial production as a joint-venture by Remington Arms Company and Ruger in 1983 as a new chambering for the Ruger ...
Black powder substitutes are measured by volumetric measurement techniques, not in grains on a scale, due to the difference in density compared to black powder. For example, to measure a "60 grain equivalent" of black powder substitute suitable for use in a muzzleloader rifle, one uses a volumetric measure that produces a volume of black powder ...
More powerful loadings can basically equal the highest performing .357 Magnum loads, and retain more kinetic energy at 100 yards than the .45 ACP has at the muzzle. [ 12 ] The 10mm outperforms the .40 S&W by 150–300 ft/s (46–91 m/s) for similar bullet weights when using available full-power loads, [ 31 ] as opposed to the "10mm FBI" level ...
Finnish smokeless powder. Smokeless powder is a type of propellant used in firearms and artillery that produces less smoke and less fouling when fired compared to black powder. Because of their similar use, both the original black powder formulation and the smokeless propellant which replaced it are commonly described as gunpowder.
