Handloading. 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 ...
The .223 Remington (designated 223 Remington by SAAMI [4] and 223 Rem. by the C.I.P. [5]) is a rimless, bottlenecked, centerfire intermediate cartridge.It was developed in 1957 by Remington Arms and Fairchild Industries for the U.S. Continental Army Command of the United States Army as part of a project to create a small-caliber, high-velocity firearm.

With the advent of chemical primers, it was not long before several systems were invented with many different ways of combining bullet, powder, and primer into a single package which could be loaded quickly from the breech of the firearm. This greatly streamlined the reloading procedure and paved the way for semi- and fully automatic firearms.
The 7.5×55mm Swiss or 7,5mm GP 11 (or unofficially 7.5×55mm Schmidt–Rubin) is a cartridge developed for the Swiss Army.It originated from the Gewehrpatrone 1890 (7.5×53.5mm) developed in 1889 by mechanical engineer Lt. Col. Eduard Rubin for rifles based on Rudolf Schmidt's action design.
Ball propellant. Ball propellant (trademarked as Ball Powder by Olin Corporation and marketed as spherical powder by Hodgdon Powder Company [ 1]) is a form of nitrocellulose used in small arms cartridges. Ball propellant can be manufactured more rapidly with greater safety and less expense than extruded propellants.
Handloading is possible with 5.7×28mm ammunition, and 5.7 mm (0.22 in) bullets are widely available due to use in .223 Remington and 5.56×45mm NATO cartridges.

In guns, internal ballistics covers the time from the propellant 's ignition until the projectile exits the gun barrel. [ 1] The study of internal ballistics is important to designers and users of firearms of all types ...
