The .303 British and .308 Winchester are both popular rifle cartridges, but they have distinct differences in terms of their design, ballistics, historical background, and areas of use.
Design and Ballistics:
The .303 British is a rimmed cartridge, originally designed for the Lee-Metford rifle in the late 19th century. It has a bullet diameter of .311 inches (7.7 mm) and a case length of 2.22 inches (56.44 mm). The .308 Winchester, on the other hand, is a rimless cartridge developed in the 1950s. It has a bullet diameter of .308 inches (7.8 mm) and a shorter case length of 2.015 inches (51.18 mm).
The main difference in ballistics between the two cartridges is their velocities and energy levels. The .303 British typically fires a heavier bullet at a lower velocity, while the .308 Winchester shoots a lighter bullet at a higher velocity. As a result, the .308 Winchester generally has a flatter trajectory and greater energy transfer at longer ranges compared to the .303 British.
Historical Background:
The .303 British has a rich history, having been the standard British military cartridge for over 60 years. It was used in rifles such as the Lee-Metford, Lee-Enfield, and Bren Gun, playing a significant role in conflicts like World War I and World War II. On the other hand, the .308 Winchester was developed by Winchester primarily for civilian sporting purposes and later gained popularity among military forces.
Areas of Use:
The .303 British is still used today for civilian hunting and target shooting, particularly by enthusiasts of historical firearms. It is also popular in certain Commonwealth countries for hunting larger game, such as deer and boar. The .308 Winchester, being a more modern cartridge, is widely used for both civilian and military applications. It is a popular choice for hunting medium to large-sized game and is used by military and law enforcement agencies around the world.
Why
The differences between the .303 British and .308 Winchester cartridges exist due to variations in their historical development, intended purposes, and technological advancements. Different design considerations and the evolution of firearms led to the creation of these distinct cartridges to meet the specific needs of different time periods and applications.
When
The .303 British was introduced in 1888 and saw extensive use until the mid-20th century. The .308 Winchester was introduced in 1952 and is still actively used today.
Where (currently)
The .303 British and .308 Winchester cartridges can be found in various parts of the world where firearms enthusiasts, hunters, and military forces utilize them. Their availability may vary depending on local regulations and the specific demand within different regions.
Who
Individuals, organizations, and military forces engaged in shooting sports, hunting, and military operations may be interested in understanding the differences between the .303 British and .308 Winchester cartridges. Firearm manufacturers, ammunition producers, and ballistic experts also play a role in developing, producing, and analyzing these cartridges.

- Are there any notable ballistic studies comparing the .303 British and .308 Winchester
The .303 British typically uses bullets ranging from 150 to 180 grains, while the .308 Winchester commonly utilizes bullets ranging from 150 to 180 grains for most applications.
The .308 Winchester generally offers better long-range accuracy compared to the .303 British due to its higher muzzle velocity, flatter trajectory, and more efficient ballistics.
No, rifles chambered for .303 British should not be fired with .308 Winchester ammunition, and vice versa. The cartridges have different chamber dimensions and pressure specifications, which can lead to unsafe conditions if improperly used.
While the .303 British is no longer the standard military cartridge for any nation, it may still be used by some military and paramilitary forces in certain Commonwealth countries for ceremonial purposes.
The .308 Winchester generally has a longer effective range compared to the .303 British due to its higher muzzle velocity, flatter trajectory, and improved ballistics.
While the availability of rifles chambered for .303 British is more limited compared to the .308 Winchester, there are still some modern production rifles available from various manufacturers specializing in historical or vintage firearms.
Both cartridges are suitable for hunting a wide range of game, such as deer, boar, and elk, depending on the bullet selection and local regulations. However, due to its flatter trajectory and higher energy levels, the .308 Winchester is often preferred for larger game and longer-range hunting.
While specific ballistic studies comparing these cartridges may exist, an up-to-date mention of such studies could not be found. It is recommended to consult reputable ballistics resources and studies for the most accurate and recent information.
