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 ...
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.
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)
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 .41 AE can be ballistically similar to the .40 S&W, to the point that many reloading manuals suggest using .40 S&W load data in the .41 AE. Original IMI factory cartridges are much higher powered, approaching 10mm levels, pushing a 170 gr (11.02 g) bullet at 1215 ft/s. The .41AE actually outperforms the .40SW by a significant amount.
For handgun cartridges, with heavy bullets and light powder charges (a 9×19mm, for example, might use 5 grains (320 mg) of powder, and a 115 grains (7.5 g) bullet), the powder recoil is not a significant force; for a rifle cartridge (a .22-250 Remington, using 40 grains (2.6 g) of powder and a 40 grains (2.6 g) bullet), the powder can be the ...
Making the 9×25mm Dillon is fairly easy. Dillon Precision makes the necessary resizing die, and reliable reloading data is easily found. Most people use 115- to 125-grain bullets, but bullets with weights as low as 80 grains are used, too.
A common approach to product safety involved offering ammunition safe for use in the oldest or weakest firearm chambered for that cartridge. Owners of stronger firearms found and experimented with Hodgdon's previously unknown powders to achieve ballistics superior to available factory ammunition for older cartridges like the 7.92×57mm Mauser.
