SIM-X ammunition is not like other ammunition. To understand it requires rethinking what constitutes performance in a round. Get ready to change your understanding of bullets, mass, velocity, and terminal performance.


DEFENSECORE™ from SIM-X is the first of its kind ammunition for every-day carry, combining hyper-velocity, performance recoil, and optimized on-target, in-target terminal performance when needed most. The patented synthetic-polymer core is perfectly married to the proprietary jacket, achieving outstanding performance in all handguns in the areas that matter most. The 9mm offers an astounding 500+ foot pounds of energy at the muzzle… something previously unheard of in most small pistol rounds. DEFENSECORE™ helps put devastating rounds on target, in critical situations when it matters the most.

Our RANGECORE™ ammunition creates its own category of projectile technology with its patented synthetic core inside a precision alloy jacket. Our synthetic core is a heavy-duty material that cycles firearms smoothly and effectively. It does so without any modification to the firearm or added wear, tear and recoil of a +P cartridge. RANGECORE™ is the first in a line of SUBMASS™ projectiles that boasts twice the velocity but only half the recoil of any other training round on the market. This Performance Recoil & Hyper-Velocity round translates into greater accuracy with more rounds on target in a shorter amount of time. RANGECORE™ ammunition is offered in Full Metal Jacket (FMJ) configurations in 9mm, .40S&W, and .45ACP.

Our DUTYCORE™ ammunition is designed from the ground up to stop the threat. It encompasses a patented Kinetic ceramic core within a precision alloy jacket. DUTYCORE™ uses our SUBMASS™ projectile technology to provide the most effective combination of Kinetic energy and penetration available in a pistol caliber. DUTYCORE™ ammunition yields rifle velocities in pistol calibers, and at standard pressures. Unlike standard pistol rounds, the extreme velocity of SIM-X DUTYCORE™ ammunition creates permanent wound cavities. DUTYCORE™ also uses patented penetration control technology to ensure your shot will stay in your target, expending all its energy where it matters most ensuring elimination of the threat. With SUBMASS™ technology, DUTYCORE™ offers a similar feel to our RANGECORE™ ammunition. This makes tactical training with RANGECORE™ cost effective and transitioning to DUTYCORE™ easy, which ultimately means more rounds on target. DUTYCORE™ is available in Hollow Point (HP) configurations in 9mm, .40S&W, and .45ACP.

Our BATTLECORE™ ammunition is custom built for our military personnel. BATTLECORE™ encompasses a special purpose patented Kinetic ceramic core inside a full metal copper jacket. BATTLECORE™ utilizes the same SUBMASS™ projectile technology that translates into effective barrier penetration, higher velocities, flatter trajectories, and lower recoil tailored for fully automatic weapons. SIM-X Ammunition pushes through the technological envelope to ensure the best available ammunition for our warfighters.
