Although not originally designed for handguns, several rifle and shotgun cartridges have also been chambered in a number of large handguns, primarily in revolvers like the Phelps Heritage revolver, Century Arms revolver, Thompson/Centre Contender break-open pistol, Magnum Research BFR, and the Pfeifer Zeliska revolvers.
20 mm caliber is a specific size of popular autocannon ammunition. The dividing line between smaller-caliber weapons, commonly called " guns ", from larger-caliber " cannons " (e.g. machine gun vs. autocannon ), is conventionally taken to be the 20 mm round, the smallest caliber of autocannon.
A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters. [2] Chg: Propellant charge, in grains; Dia: Bullet diameter, in inches; BC: Ballistic coefficient, G1 model; L: Case length (mm)
The .500 Linebaugh utilizes a bore diameter of .500" with the corresponding bullet diameter of .510", the same as the .50 BMG and other .50 caliber rifles, while the .50 Action Express, .500 S&W Magnum, and .500 S&W Special use .490" bore diameters and correspondingly smaller .500" bullet diameters. The smaller .500" diameter was further ...
The ballistics of the .950 JDJ are more similar to that of the 20 mm autocannon round, which delivers approximately 39,500 foot-pounds force (53,600 joules). The muzzle energy of the .950 JDJ is comparable to the kinetic energy of a 2,800 pounds (1,300 kilograms) automobile traveling at 20 miles per hour (32 kilometres per hour).
The .50 GI has developed a reputation for accuracy, though this may be due to the high precision of the semi-custom and very expensive Guncrafter pistols themselves. In one test, the 300 grain (19 g) jacketed flatpoint (JFP) gave a 25-yard group of 2.56 inches, and the 300-grain Jacketed hollow point (JHP) and 275-grain JHP gave a 25-yard group ...
An open single-cavity bullet mold and a closed two-cavity mold. A cast bullet is made by allowing molten metal to solidify in a mold.Most cast bullets are made of lead alloyed with tin and antimony; but zinc alloys have been used when lead is scarce, and may be used again in response to concerns about lead toxicity.
Introduced for the Remington Navy single-shot, rolling block pistol in 1865, the low-velocity round loaded a 290 gr (19 g; 0.66 oz) bullet over 23 gr (1.5 g; 0.053 oz) of black powder. [ 1 ] The rimfire version was replaced in 1866 by a centerfire equivalent.
