.303 British Ammo

The .303 British, also known as the 7.7x56mmR, is a historic rimmed rifle cartridge that was first introduced by the British military in 1889. The cartridge gained widespread recognition as the primary service round for the British Empire and Commonwealth forces throughout the late 19th and early-to-mid 20th centuries, serving in iconic firearms such as the Lee-Enfield bolt-action rifle and the Vickers machine gun. Although largely replaced in military service by more modern cartridges, the .303 British remains popular among collectors, hunters, and sport shooters who appreciate its rich history and versatile performance.


The .303 British features a rimmed, bottleneck case that is typically loaded with .311-inch (7.7mm) diameter bullets weighing between 150 and 215 grains. The cartridge delivers muzzle velocities ranging from 2,400 to 2,700 feet per second, depending on the bullet weight and powder charge. The .303 British is known for its moderate recoil and respectable accuracy, making it a suitable choice for medium-range shooting and hunting applications.

In terms of hunting, the .303 British is well-suited for taking medium-sized game such as deer, antelope, and wild boar at ranges up to 200-300 yards. Its performance on larger game like elk and moose can be adequate with proper bullet selection and shot placement. However, it may be considered less ideal for long-range shooting or hunting larger game when compared to some of the more powerful modern cartridges.

Today, the .303 British is a respected and enduring cartridge that holds a special place in the hearts of many shooters and hunters who appreciate its historical significance, performance, and compatibility with classic military firearms. While it may not match the ballistics of some modern cartridges, the .303 British continues to offer a unique and enjoyable shooting experience for those who value its rich heritage and practical capabilities.
