Reloading is the process of reusing an empty cartridge case and fitting it with a new projectile, a new powder charge and a new primer. The main advantage of reloading is that the ammunition can be optimized to the individual needs of the shooter and the specific requirements of the weapon. However, there is also potential for danger in one's own manufacturing process if, for example, ammunition is overloaded, i.e. too much powder is used. A pleasant side effect of reloading is that it is cheaper than factory ammunition, because the most expensive part of the ammunition is often the cases, which are recycled here. For reloading, in addition to the individual ammunition components, a reloading press and so-called dies are necessary special tools.
