The .10mm Magnum Ammo, also known as the 10mm Mag Ammo, is a centerfire pistol cartridge that looks a bit obscured. Its origins date back to Arcadia Machine & Tool, in a version of the Automag series of pistols. The .10mm Magnum Ammo is mostly a lengthened version of the 10mm Auto Ammo, which was intended to achieve significantly higher velocities and be appropriate for hunting, competition target shooting, and so on. The longer case wasn't the only change made to the .10mm Magnum Ammo, but it also had thicker internal portions to the rim and flash hole. The ballistic performance of the .10mm Magnum Ammo delivers a significant increase in the energy levels over the .10mm Auto Ammo and can be fairly compared to many of the .41 Remington Magnum Ammo. The 200-grain bullet variant of the .10mm Magnum Ammo can travel at a velocity of 1,620 feet per second while creating an energy level of 1,165 ft.lbf. The most popular gun to ever have the .10mm Magnum Ammo chambering is none other than the AMT AutoMag IV.
The .10mm Magnum Ammo provides strong firepower with a good level of accuracy, making it suitable for self-defense against dangerous and big predators when you go out for hunting.
