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 ...
Smith & Wesson models 78G and 79G are vintage models of air-powered pistols. Each model chambered either a .177 or .22 caliber pellet. The Smith & Wesson G-series pistols were designed with attention to accuracy and weight, making them ideal in developing short-range marksmanship skills while using a less-penetrating, air-driven pellet as the projectile.
The .17 HMR is essentially a .22 WMR cartridge necked down to accept a .17-caliber bullet and is used as a flat-shooting, light-duty varmint round. The .17 HMR was followed up by Hornady's .17 Mach 2, or .17 HM2 in 2003, which is based on a slightly lengthened and necked-down .22 Long Rifle cartridge.
.22 caliber, or 5.6 mm, refers to a common firearms bore diameter of 0.22 inch (5.6 mm) in both rimfire and centerfire cartridges. Cartridges in this caliber include the very widely used .22 Long Rifle and .223 Remington/5.56×45mm NATO. .22 inch is also a popular air gun pellet caliber, second only to the ubiquitous .177 caliber.
Using the same 40 gr (2.6 g) outside-lubricated bullet later adapted for the much more common .22 long rifle, [2] the extra long was loaded with 6 gr (389 mg) of black powder. [2] Originally, it slightly outperformed the .22 LR, but was "not noted for great accuracy", [2] while later smokeless loads achieved about the same muzzle velocity as ...
The .22 TCM (Tuason, Craig, Micromagnum) is a proprietary bottlenecked rimless cartridge derived from a 5.56×45mm NATO (.223 Remington) parent case. It was developed by custom gunsmith Fred Craig in collaboration with Martin Tuason, the President of Rock Island Armory (RIA) and Armscor.
Two years later, in 1965, Remington Arms adopted the .22-250, added "Remington" to the name and chambered their Model 700 and 40 XB match rifles for the cartridge along with a line of commercial ammunition, thus establishing its commercial specification. [6] The .22-250 was the first non-Weatherby caliber offered in the unique Weatherby Mark V ...
The Model 1322 is a pneumatic pump-action air pistol utilizing .22 (5.5 mm) caliber lead pellets. The pistol's integral pump lever mechanism is located underneath the barrel, integral to the forearm. This pump lever is cycled a variable number of times (up to a maximum of ten strokes) to store increasingly pressurized air in a chamber.
