In January 2009 the Finnish ammunition manufacturer Lapua published Doppler radar tests derived drag coefficient data for most of their rifle projectiles. [1] [2] The predictive capabilities of the custom mode are based on actual bullet flight data derived from Doppler radar test sessions. With this data engineers can create algorithms that ...
External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin stabilized, flying through an atmosphere or in the vacuum of space, but most certainly flying under the influence of a gravitational field.
The .450 Bushmaster is descended from the Thumper concept popularized by the gun writer Jeff Cooper.Cooper was dissatisfied with the small-diameter 5.56×45mm NATO (.223 Remington) of the AR-15, and envisioned a need for a large bore (.44 cal or greater) cartridge in a semi-automatic rifle to provide one-shot kills on big-game animals at 250 yards.
Soon after the release of the .223 Remington as a commercial cartridge, shooters began experimenting with the cartridge in an attempt to improve its performance. [1] Several of these experimenters necked up the .223 Remington to 6mm as the .243 inches (6.17 mm) caliber bullets provided better external ballistic performance over .224 inches (5. ...
At the 2023 SHOT Show in Las Vegas, Nevada, the .360 Buckhammer cartridge was introduced by Remington Arms.The Sporting Arms and Ammunition Manufacturers' Institute (SAAMI), the U.S. firearms and ammunition industry's technical standards-setting organization, announced the acceptance of the new cartridge and chamber standard on January 15, 2023.
The 6.5 mm (.264 caliber) has been extremely popular in Europe and especially in the Scandinavian countries and this trend continues today. [5] The 6.5×52mm Carcano, 6.5×53mmR (.256 Mannlicher), 6.5×54mm Mannlicher-Schönauer, 6.5×55mm Swedish Mauser, 6.5×58mmR Krag–Jørgensen and the 6.5×58mm Portuguese are among these cartridges of originally military European origin.
The 6.8mm Remington Special Purpose Cartridge (6.8 SPC, 6.8 SPC II or 6.8×43mm) is a rimless bottlenecked intermediate rifle cartridge that was developed by Remington Arms in collaboration with members of the U.S. Army Marksmanship Unit and United States Special Operations Command [6] to possibly replace the 5.56 NATO cartridge in short barreled rifles (SBR) and carbines.
Extremely high initial velocity (over 4,000 ft/s 1,200 m/s), flat trajectory and very low recoil are the .17 Remington's primary attributes. It has a maximum effective range of about 440 yards (400 m) on prairie dog -sized animals, but the small bullet's poor ballistic coefficients and sectional densities mean it is highly susceptible to ...
