Breechloader
A firearm loaded through an opening at the rear of its barrel. Its breech must close securely to contain the pressure produced when ammunition fires.
Breech mechanism: The system that opens and closes a firearm’s breech for loading and firing. It provides the rear opening that makes breech loading possible.
Muzzleloader: A firearm loaded by inserting ammunition through the muzzle, the front end of its barrel. It uses the opposite loading route from a breechloader.
Johann Nikolaus von Dreyse: A German gunsmith who developed the Dreyse needle gun, an influential nineteenth-century breechloader. His rifle helped demonstrate the battlefield potential of breech loading.
Bolt-action: A firearm action operated by manually cycling a bolt to load, lock, fire, extract, and eject cartridges. It is a widely used breech-loading action for rifles.
Battle of Königgrätz: The 1866 battle in which Prussian forces defeated Austria during the Austro-Prussian War. Prussian breech-loading rifles contributed to a marked firepower advantage.
Cartridge: A unit of ammunition combining a projectile, propellant, primer, and usually a case. Its compact, self-contained form made repeated breech loading practical.
Flintlock: An ignition system that uses flint striking steel to produce sparks and fire a gunpowder charge. Flintlocks are commonly associated with muzzle-loading firearms, though the ignition system is distinct from loading method.
Dreyse needle gun: A Prussian bolt-action breechloader adopted in the mid-nineteenth century and used in major European wars. Its military service made rapid breech loading a strategic advantage.
Lever-action: A firearm action that cycles cartridges by moving a lever around the trigger area. Its lever operates the breech and often feeds ammunition from a magazine.
Franco-Prussian War: The 1870–1871 conflict in which Prussia and its German allies defeated France. Both sides fielded breech-loading rifles, exposing their influence on modern warfare.
