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 patent pending synthetic-polymer core is perfectly married to the proprietary jacket, achieving outstanding performance in all handguns in the areas that matter most. DefenseCore™ helps put devastating rounds on target, in critical situations when it matters the most.
The SIM-X SubMass™ core(s) are approximately 80% – 90% lighter than standard lead core ammunition, but with equal or greater impact and tensile strength. Combined with muzzle velocities nearly twice that of standard pistol and carbine rounds these SubMass™ projectiles are light weight but have heavy impact. All of this is accomplished without firearm modification or the need for +P pressures.
SYNTHETIC COMPOSITE CORE
SIM-X proprietary synthetic core is a heavy-duty viscoplastic material that behaves as a solid but has the characteristics of a non-Newtonian fluid. The result is a lightweight, SubMass™ projectile that achieves a better gas seal in the bore. This translates into very high velocities combined with perfect control over penetration and expansion, cycling the firearm without the need for weapon modification or +P pressures.
The Kinetic-Ceramic core is 10X stronger than lead with a polymer matrix that produces flexible properties. These properties create a projectile that achieves a better gas seal in the bore, allowing significantly higher velocities. Additionally, SubMass™ technology cycles firearms smoothly and effectively and without modification or +P pressures.
SubMass™ core technology yields an additional important benefit, namely weight savings. 50 rounds of SIM-X .45 ACP are approximately 53% lighter than the same quantity of standard 230 grain .45 ACP. The advantages of lighter ammo are obvious, but here’s what our friends in the military have to say about it.
SIM-X SubMass™ bullet technology produces lower recoil. Using our proprietary jacket and viscoplastic or kinetic-ceramic core, we are able to produce very high velocities with an efficiency that avoids +P pressures and the need to alter the firearm in any way.
SIM-X patent pending synthetic and kinetic-ceramic core materials are 100% non-toxic. For LE 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.
