950 JDJ vs 50 BMG: The Ultimate Caliber Comparison
When it comes to large caliber rifles, two rounds often come to mind: the 950 JDJ and the 50 BMG. Both are known for their massive size, incredible power, and limited practical applications. However, they have distinct differences in terms of design, performance, and usage. In this article, we will delve into the world of these giant calibers and compare the 950 JDJ and 50 BMG in various aspects.
History and Development
The 50 BMG (Browning Machine Gun) was developed in the early 20th century for use in the M2 Browning machine gun. It was designed to provide a high-powered, long-range cartridge for military applications. The 50 BMG has since become a popular choice for civilian shooters, particularly among those interested in extreme long-range shooting and hunting large game.
On the other hand, the 950 JDJ is a more recent development, created by J.D. Jones of SSK Industries in the 1990s. It was designed to be a more powerful alternative to the 50 BMG, with a focus on hunting large and dangerous game. The 950 JDJ is not as widely adopted as the 50 BMG, but it has gained a loyal following among some shooters.
Cartridge Dimensions and Ballistics
The 50 BMG cartridge measures 5.45 inches (138.4 mm) in length, with a case length of 3.91 inches (99.3 mm) and a bullet diameter of 0.51 inches (12.95 mm). It has a maximum pressure of 54,000 psi (372,000 kPa) and a typical muzzle velocity of around 2,700 ft/s (823 m/s).
The 950 JDJ cartridge is significantly larger, measuring 6.5 inches (165.1 mm) in length, with a case length of 4.65 inches (118.1 mm) and a bullet diameter of 0.60 inches (15.24 mm). It has a maximum pressure of 65,000 psi (448,000 kPa) and a typical muzzle velocity of around 2,400 ft/s (732 m/s).
Cartridge Comparison Table
| Cartridge | Length | Case Length | Bullet Diameter | Max Pressure | Muzzle Velocity |
|---|---|---|---|---|---|
| 50 BMG | 5.45 in (138.4 mm) | 3.91 in (99.3 mm) | 0.51 in (12.95 mm) | 54,000 psi (372,000 kPa) | 2,700 ft/s (823 m/s) |
| 950 JDJ | 6.5 in (165.1 mm) | 4.65 in (118.1 mm) | 0.60 in (15.24 mm) | 65,000 psi (448,000 kPa) | 2,400 ft/s (732 m/s) |
Performance and Range
The 50 BMG is known for its exceptional long-range performance, with a flat trajectory and minimal wind deflection. It is capable of engaging targets at distances exceeding 2,000 yards (1,800 meters). However, its performance begins to degrade at ranges beyond 2,500 yards (2,300 meters).
The 950 JDJ, on the other hand, is designed to provide maximum kinetic energy at closer ranges. Its heavier bullet and higher pressure result in a more dramatic trajectory, but it is still capable of engaging targets at ranges exceeding 1,500 yards (1,370 meters).
Range Comparison Chart
| Cartridge | 500 yd (457 m) | 1,000 yd (914 m) | 1,500 yd (1,372 m) | 2,000 yd (1,829 m) |
|---|---|---|---|---|
| 50 BMG | 1,800 ft/s (549 m/s) | 1,400 ft/s (427 m/s) | 1,000 ft/s (305 m/s) | 600 ft/s (183 m/s) |
| 950 JDJ | 1,600 ft/s (488 m/s) | 1,200 ft/s (366 m/s) | 800 ft/s (244 m/s) | 400 ft/s (122 m/s) |
Practical Applications
The 50 BMG is widely used in various military and civilian applications, including:
- Long-range target shooting
- Hunting large game (e.g., elk, moose)
- Tactical and law enforcement applications
The 950 JDJ, due to its limited adoption and availability, is primarily used for:
- Hunting large and dangerous game (e.g., elephant, rhino)
- Extreme long-range shooting
Conclusion
The 950 JDJ and 50 BMG are both massive calibers with unique characteristics and applications. While the 50 BMG is widely adopted and versatile, the 950 JDJ is a more specialized cartridge designed for specific hunting and shooting applications. Ultimately, the choice between these two calibers depends on the shooter’s specific needs and preferences.
