What is a 4 Bore? A Deep Dive into its Definition and History
The “bore” of a firearm refers to the internal diameter of the gun barrel. The bore size is often expressed in gauges or calibers. A 4 bore firearm is defined by having a bore diameter that allows four spherical lead balls of that diameter to weigh one pound. This translates to a massive bore size, typically around 1.052 inches (26.7 mm).
The concept of bore measurement originated in the days of smoothbore muzzleloaders. The term “bore” referred to the number of same-sized spherical balls that could be made from a pound of lead. Therefore, a 4 bore weapon used projectiles so large that only four of them equaled a pound.
The 4 bore was primarily developed in the 19th century, a time when large-bore firearms were used for hunting dangerous game, such as elephants, rhinoceroses, and tigers. These weapons were essential tools for hunters and explorers in Africa and Asia, providing the stopping power needed to bring down extremely large and aggressive animals.
Historical Context and Development
The 4 bore emerged as a response to the need for firearms capable of delivering immense energy on impact. Early black powder rifles and shotguns lacked the power to reliably stop large, thick-skinned animals. The 4 bore filled this gap, offering a dramatic increase in projectile mass and kinetic energy.
Key milestones in its development include:
