What is the biggest bullet?

Answered by Robert Dupre

The biggest bullet currently in production is the .950 JDJ. This massive round has a bullet diameter of 0.950 inches (24.1 mm) and a case length of 2.75 inches (70 mm). It is a truly massive projectile designed for extreme power and performance.

The .950 JDJ cartridge was developed by American gunsmith and firearms enthusiast J.D. Jones. It was specifically designed for use in his custom-made firearms. The bullet used in this cartridge weighs a staggering 3,600 grains (233 grams), which is equivalent to 0.82 pounds or 13.3 ounces.

When fired, the .950 JDJ round achieves an impressive velocity of 2,200 feet per second (670 meters per second). This incredible speed, combined with the massive bullet weight, results in an astonishing amount of energy. The muzzle energy of the .950 JDJ is a staggering 38,685 foot-pounds (52,450 joules).

To put this into perspective, the .950 JDJ round packs more than 20 times the muzzle energy of a typical .50 BMG round, which is already known for its tremendous power. This level of energy is simply unmatched by any other commercially available cartridge.

The .950 JDJ is not a round for the faint of heart. It is intended for specialized applications such as long-range shooting, big game hunting, and military use. Due to its massive size and power, firearms chambered in .950 JDJ are extremely rare and typically custom-made.

The recoil produced by the .950 JDJ is also extreme, and shooting it requires significant skill and strength to handle the immense power. The noise and muzzle blast generated by this round are also substantial, making hearing protection a must.

I have never personally fired a firearm chambered in .950 JDJ, as it is an extremely uncommon round. However, I have had the opportunity to handle and examine firearms chambered in other large calibers, such as .50 BMG and .577 Tyrannosaur. The sheer size and weight of these cartridges are impressive, and it’s easy to imagine the immense power they deliver.

The .950 JDJ is the largest bullet currently in production, with a massive bullet diameter of 0.950 inches and a weight of 3,600 grains. It is a cartridge designed for extreme power and performance, with a muzzle energy surpassing any other commercially available round. Handling and shooting firearms chambered in .950 JDJ require significant skill, strength, and precautions due to the immense recoil and power involved.
