As a result, the chamber pressure was higher, at 40,000 to 42,000 psi (275.8 to 289.6 MPa), depending upon loading, compared to the 39,000 psi (268.9 MPa) of the Mark VII(z) round. The.303 British cartridge was first conceived in 1888 and immediately adopted as the standard service rifle round for the British Empire (later, by the British Commonwealth). These bullets are identical in trajectory until about the 130 yard mark. The original .303 British service cartridge employed black powder as a propellant, and was adopted for the Lee–Metford rifle, which had rifling designed to lessen fouling from this propellant. As a result, it was prohibited from general use with rifles and light machine guns except when low flash was important and in emergencies[27] As a consequence of the official prohibition, ordnance personnel reported that every man that could get his hands on Mk VIIIz ammunition promptly used it in his own rifle.[23]. In the year 1910, the caliber was modified with a 147-grains Spitzer bullet and with a smokeless propellant load. This is accomplished by increasing the shoulder angle from 16 to 35 degrees, and reducing the case taper from .062 inches to .009 inches. [7]

This allowed around 1,860fps from a 70-grain compressed load and a 215-grain round nose bullet. Your email address will not be published. The first number is the value of this cartridge, and the last number is the value of the most powerful round in our bullet database. The British and American defence was that they should not focus on specific bullet designs, like hollow-points, but instead on rounds that caused "superfluous injury". Anti-zeppelin missions typically used machine guns loaded with a mixture of Brock bullets containing potassium chlorate, Pomeroy bullets containing dynamite, and Buckingham bullets containing pyrophoric yellow phosphorus. The high-velocity 7×57mm had a flatter trajectory and longer range that excelled on the open country of the South African plains.

The de Wilde was later used in some numbers in fighter guns during the 1940 Battle of Britain.[30]. Why should hunters and shooters be worried about the EU regulation prohibiting the use and carrying of lead gunshots? 150, 160, 170, 180, and 200-grain (13 g), both for hunting and target purposes. .303 British-Remington Core-Lokt Soft Point, .303 British-Sellier & Bellot Full Metal Jacket, .303 British-Winchester Power-Point, .303 British-UMC (Remington) Metal Case, .303 British-Sellier & Bellot Soft Point, .303 British-Hornady Soft Point InterLock, .303 British-Federal Soft Point, .303 British-Federal Speer Hot-Cor SP. 4 rifles with the Colt Canada C19 chambered as evaluated in 7.62×51mm NATO/.308 Winchester. The best general-purpose ammunition for any .303 military rifle is the Mark 7 design because it provides the best combination of accuracy and stopping power. There aren't that many manufacturer's still producing the .303 today but the ones produced range from 150 to 180 grain , with ballistic coefficients ranging from .276 to .370. [8][9][10] Ballistite was a stick-type smokeless powder composed of soluble nitrocellulose and nitroglycerine. Morant was found guilty and was executed by a firing squad. .303 British maximum C.I.P. In 1891 the cartridge was adapted to use smokeless powder. The parties in the end agreed to abstain from using expanding bullets. The transition period is 2 years. Canadian Rangers use it for survival and polar bear protection. "The European …. Angus & Robertson. The Mk II round-nosed bullet was found to be unsatisfactory when used in combat, particularly when compared to the dum-dum rounds issued in limited numbers in 1897 during the Chitral and Tirah expeditions of 1897/98 on the North West Frontier of India. The .303 British cartridge was designed by a Major Rubini, superintendent of the Swiss government arms laboratory. The two had identical bullet weights and a "tail-heavy" design, as can be seen in the cut-away diagram. Adopted as a military calibre in 1988, the .303 British (which is actually a .312 bullet) saw widespread use across two World Wars before being superseded by the 7.62 NATO (.308 Win) in 1957. This interesting calibre has a lifespan of almost 114 years, even though it rarely sees use today. The nitrocellulose versions—first introduced in World War I—were designated with a "z" postfix indicated after the type (e.g. Although it appears to be a conventional spitzer-shape full metal jacket bullet, this appearance is deceptive: its designers made the front third of the interior of the Mk 7 bullets out of aluminium (from Canada) or tenite (cellulosic plastic), wood pulp or compressed paper, instead of lead and they were autoclaved to prevent wound infection. The lightweight tip material filled almost the entire ogive of the FMJ bullet in order to enhance instability on impact. [4] It was the standard British and Commonwealth military cartridge from 1889 until the 1950s when it was replaced by the 7.62×51mm NATO.[2]. The .303 British (7.7x56mmR) was the British standard round until about 1957, and had been in use for over 60 years. all4shooters.com is the international platform that is your window to this fascinating world – in four languages. David Scallan, the European Federation for Hunting and Conservation (FACE) secretary general, and Marta Gomez from the European Shooting Sports Forum (ESSF) explain what the issue is. The remaining stocks (over 45 million rounds) were used for target practice. The last tracer round introduced into British service was the G Mark 8 in 1945, the last armour-piercing round was the W Mark 1Z in 1945 and the last incendiary round was the B Mark 7 in 1942. In Canada, it was found to be adequate for any game except the great bears. In 1957 the .308 also known as the 7.62x51mm NATO became the official NATO round and was therefore adopted by the brits. In any case other bullet weights are available, e.g. Handloaders were eventually able to take advantage of much lighter heads and higher velocities than factory production. [20], The Australian movie Breaker Morant (film) features a famous popular culture reference to the .303. In-depth understanding of each individual market is our strength – along with our ability to provide worldwide distribution via the Web. .303 British - Manufacturer Loading Data Pistol Rifle Cowboy GR. Recommended bullet diameter for standard .303 British cartridges is .312-inch (7.92 mm).[6].

According to the official C.I.P. By 1910, the bullet weight had been dropped to 174 grains, increasing speeds further and bringing them more in line with the kind of velocities we would recognise today. Measured between the grooves, the nominal size of the bore is .311-inch (7.90 mm). We supply essential information about each respective market. Featuring an aircraft-grade aluminum base and a nickel alloy body, they offer far superior performance compared to traditional brass shells. Factories in other countries added greatly to this total.[31].

Factory ammunition isn't easy to find, at least in many European Countries, and neither are reloading components, but this is hardly a problem for the most enthusiastic shooters. In South Africa .303 British Lee–Enfield rifles captured by the Boers during the Boer War were adapted for sporting purposes and became popular with many hunters of non-dangerous game, being regarded as adequate for anything from the relatively small impala, to the massive eland and kudu.[33]. Originally it was loaded with a 215 grains ball and with 70 grains of black powder, which was extremely compressed within the case. The most notable military service firearms chambered for this caliber included all variants of the Lee-Metford and Lee-Enfield rifles, the Pattern 1914 and Model 1917 rifles, and the Bren machine gun. In 1910, work began on a long-range replacement cartridge, which emerged in 1912 as the .276 Enfield. in this first overview we take a look at the cartridges for long guns. Commercially produced ammunition is widely available in various full metal jacket bullet, soft point, hollow point, flat-based and boat tail designs—both spitzer and round-nosed. 253–254. However, when combined with the cordite propellant used in Mk 8 cartridges, which burns at a much higher temperature than nitrocellulose, there is increased barrel erosion. Hornady Handbook of Cartridge Reloading, Rifle-Pistol, Third Edition, Hornady Manufacturing Company, 1980, 1985, pp. ®. In 1957 the .308 also known as the 7.62x51mm NATO became the official NATO round and was therefore adopted by the brits. But if going after game larger than deer, you want a bullet that won't fragment in 16" because you need more penetration to take something like an elk or moose. In 1910, the British took the opportunity to replace their Mk VI cartridge with a more modern design. During a service life of over 70 years with the British Commonwealth armed forces the .303-inch cartridge in its ball pattern progressed through ten marks which eventually extended to a total of about 26 variations. The sixth edition of the Hornady Handbook of Cartridge Reloading shows that 35.3 grains of RL-15 powder will drive their 150 grain spire point bullet at a MV of 2200 fps. The design of the Mk IV hollow-point bullet shifted bullet weight rearwards, improving stability and accuracy over the regular round-nose bullet. Explosive bullets were not produced in the UK after 1933 due to the relatively small amount of explosive that could be contained in the bullet, limiting their effectiveness, their role being taken by the use of Mark 6 and 7 incendiary bullets. Americans would define the shoulder angle at alpha/2 ≈ 17 degrees. Our basic philosophy is to report in a balanced, impartial and journalistic neutral manner so that our users and partners in the industry can track current developments in a timely manner and better understand their impact. It started life as a black powder cartridge before the arrival of smokeless powders. Here are some .303 British specifications of interest to reloaders: bullet diameter .311-.312", maximum COL 3.075", maximum case length 2.222", SAAMI MAP 45,000 cup. In 2015, the Canadian Rangers began the process to evaluate rifles chambered for .308 Winchester.

Reduced charge loads and neck sizing are two unanimous recommendations from experienced loaders of .303 British to newcomers to the calibre.
