Ammunition Redefined


SIM-X ammunition yields ultra-high velocity, low recoil, lower weight and more shots on target. Think about that... and then get ready to rethink what ammunition is.

Tech Bullets

Higher Velocity

SIM-X ammunition generates velocities twice that of traditional pistol rounds by increasing the efficiency of the propellant/projectile combination. This is done without increased recoil or additional pressures like those found in +P loads. This massive jump in velocity yields permanent wound cavities–something previously thought to be unattainable with pistol ammunition.

SIM-X SUBMASS™ patented projectile technology combined with our revolutionary use of non-toxic bullet core material, allows us to accomplish something impossible with traditional bullets–precise penetration control. Regardless of velocity, penetration can be consistently kept within the spec intended.


Shots on target and quicker target reacquisition are paramount for the safety and success of law enforcement and military operations. SIM-X SUBMASS™ technology provides a smooth, true low recoil action that accelerates the operator’s trigger action and cadence. This results in more shots on target in less time.

Reduced Recoil
100% Biodegradable Lead-Free Core

Environmentally Designed

SIM-X patented projectile technology is 100% non-toxic. For shooting ranges across the board and military trainers, this means that tens of thousands of dollars normally allocated to bullet trap cleaning and lead recovery/mitigation can be reallocated for higher priorities within their training budgets.


Although there’s no such thing as do it all ammunition, SIM-X comes close with technology that redefines what a pistol round can actually do. With multiple configurations of projectile technology in three categories of product, offered in 9mm, .40 S&W, and .45 ACP, we make the perfect round for your needs.

DutyCore Bullet

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. All three calibers offer 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 in projectile technology with its patented synthetic core inside a precision alloy jacket. Our synthetic core is a heavy-duty viscoplastic 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 hyper-velocity, low recoil 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 patent-pending kinetic-ceramic core within a precision alloy jacket. DUTYCORE™ utilizes 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 utilizes patent-pending penetration control technology to ensure your shot will not only hit your target but 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) and Full Metal Jacket (FMJ) configurations in 9mm, .40S&W, and .45ACP.

Our BATTLECORE™ ammunition is custom built for our military personnel. BATTLECORE™ encompasses a special purpose patent-pending 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 firearms. SIM-X Ammunition pushes through the technological envelope to ensure the best available ammunition for our warfighters.
