The .50 BMG (Browning Machine Gun) cartridge is widely known for its large size and powerful capabilities, often used in heavy machine guns and sniper rifles for long-range engagements. However, there are several calibers that are even larger than the .50 BMG, designed for specific purposes such as anti-tank, anti-aircraft, and even experimental applications. These larger calibers offer increased range, penetration, and destructive power, but they also come with significant logistical challenges and are typically used in specialized roles.
Larger Calibers for Military and Specialized Use
One of the most notable calibers larger than the .50 BMG is the 20mm caliber, which is used in a variety of anti-aircraft and anti-tank applications. The 20mm cartridge is significantly larger and more powerful than the .50 BMG, with some variants capable of penetrating armor up to 40mm thick. The 20x102mm cartridge, for example, is used in the M61 Vulcan cannon, a six-barreled Gatling gun used on various military aircraft for air-to-air combat and ground attack missions.
Large Caliber Ammunition for Heavy Weapons
Even larger calibers exist, such as the 30mm and 40mm calibers, which are used in heavy anti-aircraft and anti-tank guns. The 30x113mm cartridge, for example, is used in the M230 cannon, a chain-driven, single-barrel cannon used on the AH-64 Apache helicopter for anti-armor and anti-infantry missions. The 40mm caliber is also used in various grenade launchers and anti-aircraft systems, offering increased range and lethality over smaller calibers.
| Caliber | Cartridge Length | Muzzle Velocity | Muzzle Energy |
|---|---|---|---|
| 20x102mm | 105mm | 1,030 m/s | 35,000 J |
| 30x113mm | 113mm | 790 m/s | 40,000 J |
| 40x311mm | 311mm | 1,000 m/s | 120,000 J |
Another notable example of a large caliber is the 57mm caliber, used in various naval and coastal defense applications. The 57x347mm cartridge, for example, is used in the Bofors 57mm gun, a dual-purpose naval gun used for anti-aircraft and anti-ship defense. This caliber offers increased range and lethality over smaller calibers, making it effective against a variety of targets, including fast-moving ships and aircraft.
Experimental and Obsolete Calibers
There have been several experimental and obsolete calibers that are even larger than the .50 BMG, designed for specific purposes such as anti-tank and anti-aircraft applications. The 75x495mm cartridge, for example, was used in the German 7.5 cm Pak 40 anti-tank gun during World War II, offering increased penetration and range over smaller calibers. However, these larger calibers often come with significant logistical challenges and are typically used in specialized roles.
In addition to these military applications, there are also several large calibers used in hunting and sport shooting contexts. The .600 Nitro Express and .700 Nitro Express calibers, for example, are used in large game hunting, offering increased range and lethality over smaller calibers. However, these calibers are typically used in specialized rifles and require significant expertise and equipment to handle safely and effectively.

+Calibers larger than .50 BMG are commonly used in anti-tank, anti-aircraft, and naval defense applications, as well as in hunting and sport shooting contexts. They offer increased range, penetration, and destructive power, but also come with significant logistical challenges and are typically used in specialized roles.
What are some examples of large calibers used in military applications?
+Examples of large calibers used in military applications include the 20x102mm, 30x113mm, and 40x311mm cartridges, which are used in various anti-aircraft and anti-tank guns, as well as in naval and coastal defense applications.
What are some challenges associated with using large calibers?
+Large calibers come with significant logistical challenges, including increased weight, size, and recoil, which can limit their use in certain applications. They also require specialized equipment and expertise to handle safely and effectively.
In conclusion, calibers larger than .50 BMG are used in a variety of military, hunting, and sport shooting applications, offering increased range, penetration, and destructive power. However, they also come with significant logistical challenges and are typically used in specialized roles. Understanding the characteristics and applications of these large calibers is essential for anyone involved in firearms or military operations, and can help to inform decisions about equipment and tactics.
