A breech-loading gun is a type of firearm where the ammunition is loaded into the rear part of the barrel, known as the breech. This design allows for quicker reloading compared to muzzle-loading guns, where ammunition is loaded from the front. Breech-loading guns can be single-shot or multi-shot, and they are commonly used in rifles and shotguns. The invention of the breech-loading mechanism significantly improved the efficiency and rate of fire for soldiers and hunters. This technology paved the way for modern firearms, influencing the design of many contemporary weapons, including those used by military forces and law enforcement agencies around the world.
