The .40 Super Ammo is a very powerful automatic pistol bullet that was designed and produced in 1996 in the United States. This bullet never attained mainstream attention and success and thus is produced minimally. To create a more radical and wildly performing cartridge, the .45 Winchester Magnum was necked down, and the thickness of the cartridge was increased, which gave the .40 Super Ammo a stronger case than its parent case. The .40 Super Ammo was intended to balance strength and powder capacity perfectly. All the changes that were done to the length, capacity, weight, and diameter of the .40 Super Ammo resulted in higher accuracy and performance of the bullet. The .40 Super Ammo was supposed to climb the market ladder, but it lost its momentum when Triton Cartridge sold out and later closed. The case length of the .40 Super Ammo is 25.1mm, and the bullet diameter measures 10.2mm. The 135-grain bullet is the lightest variant of the .40 Super Ammo, which can travel at a velocity of 1,800 feet per second while creating an energy level of 971 ft.lbf.
The .40 Super Ammo was co-developed by Fernando Coelho and Tom Burczynski and manufactured by Triton Cartridge in 1996.
The .40 Super Ammo is unsuitable for large game species, but it can effectively hunt small to medium-sized animals like the deer family and be used for self-defense.
