Rifles / MG Ammunition

Below is the list of the most common ammunition types for military bolt action, semi-automatic battle and sniper rifles and machine guns, with brief historical notes and basic ballistic data. Please note that some numbers are rounded and are for comparative purposes only.

6.5x50SR Arisaka

This cartridge was first issued in 1897 along with Arisaka Type 30 rifle, and became the standard ammunition for Japanese armed forces until the end of WW2. Original version of this round was loaded with round-nose bullet, which was later changed to more modern pointed bullet with introduction of the Type 38 Arisaka rifle and Type 38 6.5mm cartridges. It was used in a number of Japanese bolt-action rifles and machine guns. After the WW2, many weapons of ex-japanese origin remained in use in SE-Asia region for a significant period. No modern firearms are produced for this ammunition, and production of this round is all but gone (few ammunition manufacturers still make modern versions of this round for those people who still own old weapons).

6.5x52 Carcano

This cartridge was designed in Italy in 1890, and was since used in a number of bolt-action rifles and machine guns of Italian manufacture. No new weapons were designed for this round since the end of WW2, and today it is all but obsolete. It is worth of note that, unlike most other similar cartridges, the 6.5 Carcano retained its 'old-style' round-nosed bullet throughout most of its service life.

6.5x55 Swedish Mauser

This cartridge was developed in Sweden for military Mauser rifle in 1894, and was a standard rifle- and machine-gun ammunition of Swedish armed forces until 1960s. Unlike some other similar rounds, the 6.5x55 is still in production as, over the time, it became quite popular as a hunting and target round in several European countries. Originally used in military-type bolt-action and semi-automatic rifles and machine guns, today it is still chambered in a number of modern hunting and target rifles (mostly bolt-action), produced in several European countries (Sweden, Finland, Czech republic etc).

7x57 Spanish Mauser

This round was developed in Germany by Mauser factory for their improved rifle in 1892. It was adopted by Spanish army in 1893 along with Mauser bolt-action military rifle, and since then it was also adopted by several other South American countries as well. As a military round, this cartridge gradually became obsolete after WW2, but it is still chambered in several models of hunting rifles and thus it is still manufactured for civilian consumption (mostly loaded with hunting-type rifles).

7.35x51 Carcano

This round was developed in Italy shortly before the WW2 in an attempt to improve lethality and extend service life of the current, existing infantry weapons, originally chambered for the 6.5x52 Carcano ammunition. The curious 7.35mm caliber was choosen simply as a maximum possible bore diamater that can be safely achieved by boring out and re-rifiling old, worn out 6.5mm barrels. The cartridge cas was based on the 6.5x52 Carcano, slightly shortened and necked out. The service life of the 7.35x51 was rather short, as due to logistical problems Italian army switched back to 6.5mm ammunition during early stages of WW2. This amunition was used in Caracano-type bolt-action rifles and several light machine guns of Italian origin. Today this round is obsolete by all means.

7.5x54 M1929C

French army set to develop a new, modern rifle- and machine gun round to replace obsolete 8mm Lebel ammunition in early 1920s, and in 1924 it adopted the 7.5x58 M1924 round, which was a close copy of the German 7.92x57 round. The similarity between these two round eventually played dirty trick with French users, as loading very similar 7.92mm round into weapons chambered for 7.5mm rounds caused excsessive chamber pressures, which sometimes resulted in damage to weapon and injury to shooter. To remedy this problem, in 1929 the cartridge case was redesigned and made shorter, so 7.92mm rounds that had cases 57mm long could not be chambered in the new French weapons. After adoption of this round all 7.5mm weapons then in service were rebarreled for this shorter round. The Mle.1929 round was standard issue ammunition for French rifles (bolt action and semi-automatic) and machine guns until 1960s. Very few (if any) commercial weapons were ever chambered for this round, and today it is obsolete for all practical purposes.

7.5x55 GP11

The 7.5mm GP11 round was adopted by Swiss army in 1911 and is still in limited service with Swiss armed forces, in few remaining automatic rifles and some medium / universal machine gun. It was a standard round for Swiss army until about 1990, chambered in bolt-action and automatic rifles, light and medium machine guns and some hunting and target rifles. This ammunition is still manufactured in Switzerland as great many older 7.5mm rifles are still in civilian use there.

7.62x51 NATO / .308 Winchester

This round started its life in early 1950s as a .30 T65, an experimental cartridge for the US Army's 'light rifle' program. The T65 round was intended to replace the older and overly long .30-06 military round, while retaining similar ballistics. In 1955 it was adopted as a NATO standard rifle and machine gun ammunition, and is still used in this role in all NATO countries and many other as well. In mid-1950s it was also introduced as a commercial round by Winchester, and in this guise it is known as .308 Winchester, and is highly sucessful. Many countries still use military weapons in this caliber (mostly machine guns and sniper rifles, as well as some semi-automatic or selective-fire 'battle' rifles). Civilian weapons (hunting, target etc) for .308 Winchester are produced in many countries and in large numbers, and this cartridge (in both civilian and military versions) remains one of the most popular rifle cartridges to date.

7.62x54R

This cartridge is one of the oldest service cartridges still in military use in the world. Originally adopted by Russian army in 1891, along with bolt-action magazine fed rifle, it still remains in use after almost 120 years of continuous service. Over the time, it was chambered in a number of bolt-action and semi-automatic military rifles, several machine guns, and some civilian-type rifles (mostly hunting ones). Today this cartridge is still widely used by Russian military in machine guns and sniper rifles, and it is quite popular for hunting. Many types of military- and civilian-grade loadings are still produced in this chambering worldwide.

7.65x53 Argentine / Belgian / Turkish Mauser

This is one of the earliest cartridges, developed for Mauser-type magazine rifles during late 19th century. It was originally adopted by Belgian army in 1889, with round-nose FMJ bullet. Later it was adopted by Turkey and a number of South American countries, most notably Argentine. It was chambered in Mauser-type rifles and certain types of machine guns. Today this cartridge is mostly obsolete, although some manufacturers still produce this cartridge for civilian use.

.30-06 US / 7.62x63

This cartridge was born in 1906 as an evolution of the short-living .30-03 cartridge, that was originally adopted by US Army in 1903 with round-nose bullet. The .30 caliber M1906 cartridge, today universally known as .30-06, had slightly different case and, more important, it was loaded with pointed bullet. It served with US armed forces through both world wars and Korean war, and was gradually replaced in service with 7.62x51 NATO since 1957. It is still extremely popular worldwide as a hunting and target round, with new weapons (mostly bolt-action and semi-automatic rifles) and ammnuition being manufactured in many countries and in many styles.

.300 Winchester Magnum

This round was developed during 1950s by Winchester in an atempt to provide huntes with flat-shooting, long-range hunting ammunition with significant striking power. Over the time this cartridge also found its way into military and law-enforcement use as a long-range sniping round, with practical ranges up to 1000-1200 meters (as opposed to 700-800 meters with most sommon 7.62x51 / .308 Win ammunition). Many hunting and some sniper rifles are produced for this round in many parts of the world.

.303 British / 7.7x57R

Originally adopted by British army in 1889, this cartridge remained in front-line service throughout British empire (later British Commonwealth) until late 1960s. Many surplus weapons chambered for this cartridge are still in civilian use, and commercial ammunition is still in limited production for those who own those old rifles.

7.7x58SR Type 92

This round was adopted by Japanese army in 1932 (2592 per Japanese calendar then in use) as a dedicated medium machine gun round, to improve machine guns performance compared to earlier weapons, chambered for relatively 'weak' 6.5x50SR ammunition. Only machine guns were manufactured for this round, and no weapons for it were made after the end of WW2. Today it is strictly obsolete.

7.92x57 Mauser

This is one of the most sucessful European rifle rounds. Originally adopted by German army in 1888 and loaded with round-nose bullet, it was later upgraded with introduction of the pointed (Spitzer) bullet of slightly different diameter, and served with German military through both World wars. It was also a standard round with other European armies, most notably Czechoslovak, Polish, Portuguese, Yugoslavian and few others. While in most countries this round is long obsolete as a military loading, it is still quite popular as a hunting round, and many countries still produce both rifles and ammunition in this caliber.

This round was developed during early 1930s on request from Italian army, as a dedicated medium machine gun ammunition, to provide longer effective range and better lethality when compatred to 6.5mm and 7.35mm rifle ammunition. Only few models of machine guns were developed or converted from earlier systems to fire this cartridge, and it never was chambered in any type of rifle (at least, no mass-produced rifles in this caliber exist). It became obsolete shortly after the WW2, and is long out of production.

.338 Lapua Magnum / 8.58x71

This cartridge is a purpose-designed round for long-range sniper shooting. It started its life as experimental .338/416 round, developed in around 1983 in USA by Research Armament Industries. It was based on the .416 Rigby case, necked down to .338 caliber and loaded with low-drag bullet. In 1984 RAI contracted finnish company Lapua to make production ammunition, and it soon caught up as a long-range sniper round with effective range against human targets being up to 1500 meters. Today this round is widely used in long range sniping role b military and law enforcement agencies worldwide, with many rifles being bulit for it (not surprisingly, most are bolt-action repeaters). There also few long-range target and hunting rifles in this caliber. Ammunition in this caliber is manufactured in several countries and wildey available, although expensive.

9.3x64 (9SN)

This is a specialised 'medium-heavy' sniper rifle round, recently developed in Russia to fill the gap between 7.62mm sniper and 12.7mm anti-material rifles. It is based on the old and proven 9.3x64 Brenneke hunting cartridge, and is loaded with jacketed, semi-armor piercing bullet to provide certain anti-materiel effect and defeat body armor at ranges up to 600 meters. Despite its dimensions, it is no match to .338 Lapua Magnum in accuracy and long range. So far only one weapon was observed firing this cartrdge, the semi-automatic SVD-K rifle, also of Russian origin.
