Handloaded
Handloading, or reloading, is the practice of making firearm cartridges by assembling the individual components (case, primer, propellant, and projectile), rather than purchasing mass-assembled, factory-loaded ammunition. The term ''handloading'' is the more general term, and refers generically to the manual assembly of ammunition. ''Reloading'' refers more specifically to handloading using previously fired cases and shells. The terms are often used interchangeably however, as the techniques are largely the same, whether the handloader is using new or recycled components. The differences lie in the initial preparation of cases and shells; new components are generally ready to load, while previously fired components often need additional procedures, such as cleaning, removal of expended primers, or the reshaping and resizing of brass cases. Reasons for handloading Economy, increased performance and accuracy, commercial ammunition shortages, and hobby interests are all ...

Overpressure Ammunition
Overpressure ammunition, commonly designated as +P or +P+, is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round. This is done typically to produce rounds with a higher muzzle velocity and stopping power, such as ammunition used for defensive or hunting purposes. Because of this, +P ammunition is typically found in handgun calibers which might be used for defensive purposes. +P vs. magnum cartridges Magnum cartridges, such as the .357 Magnum, are usually developed by greatly increasing the working pressure of an existing cartridge, and the resulting cartridges are typically different in some small manner to prevent them from being chambered in firearms not specifically designed for them. For example, the .357 Magnum is slightly longer than the .38 Special, which is the parent cartridge of lower pressure from wh ...
