Frequently Asked Questions
What Is SUBMASS™?
SUBMASS™ is classified as a new weight category in bullet technology. It is the lightest defensive and range/training ammunition on the market; even lighter than frangible ammunition. Example: the standard weight of a 9mm civil defense ammunition is 124gr. The SIM-X 9mm DEFENSECORE™ 45gr is 2.75gr lighter. The standard weight for the 45 ACP ball ammunition is 230gr. The SIM-X RANGECORE™ 80gr is 2.875 lighter.
What Is SUBMASS™ Technology?
SIM-X Patented SUBMASS™ technology is what, why and how a lead-free, ultra-light weight ammunition can reliably function with off-the-shelf firearms, at velocities 2X that of lead ammunition, including a customized ballistics outcome, with nearly a 100% penetration control.
What Is Hyper Velocity?
SIM-X ammunition produces rifle velocities in a handgun—twice as fast as lead ammunition. The average velocity of a lead 9mm civil defense or training/range ammunition is 1100 feet per second. The 9mm DEFENSECORE™ velocity is 2250+ feet per second. The average velocity of a lead 45 ACP civil defense or training/range ammunition is 890 feet per second. The 45 ACP DEFENSECORE™ velocity is 1825+ feet per second.
What Is Performance Recoil?
As the lightest ammunition, SIM-X also produces the lightest recoil. Through mechanical measurement via the Ransom Rest, SIM-X 9mm DEFENSECORE™ registers, on average, 40% lighter recoil than a 124gr lead civil defense ammunition. SIM-X 45 ACP DEFENSECORE™ registers, on average, 50% lighter recoil than a 230gr lead civil defense ammunition. This provides better firearm management, which is important for all shooters. Less recoil equals less shooter fatigue and faster follow-up shots. Shooters simply perform better. Performance recoil is to be experienced and enjoyed.
Is Your Ammunition Lead Free?
Our patented projectile/bullet technology is 100% lead free. The anatomy of the projectile/bullet consists of a standard copper alloy jacket with a synthetic, nontoxic, polymer core. The other components are an off-the-shelf case, powder and primers.
What Does it Cost?
The SIM-X DEFENSECORE™ product line is priced the same as other premium civil defense ammunition. The SIM-X RANGECORE™ product line is the most cost-effective, lead-free ammunition on the market—up to 30% cheaper than frangible ammunition. If you are looking for a premium, lead-free bullet with performance recoil to train at the range, then the few extra pennies are worth the cost.
What Is SMART BULLET™ TECHNOLOGY?
Achieving absolute penetration control can now be realized with SIM-X SMART BULLET™ TECHNOLOGY, regardless of velocity. The SIM-X DEFENSECORE™ patented design produces the highest transfer of energy for the 9mm, 40 S&W and 45 ACP pistol calibers while maintaining nearly 100% penetration control. DEFENSECORE™ bullets can penetrate any type of clothing and harden materials without clogging the nose of the bullet. This is accomplished by expanding from the base to the nose—a first in bullet technology. The result is the greatest possible expansion generated by any bullet on the market.
What Is Barrel Burnout?
Every barrel has a shelf life; some longer than others. In the world of lead, higher velocities typically equal higher pressures, and, as such, greater wear on the barrel and chamber. This also changes the muzzle velocity through the life of the barrel. If the projectile/bullet is lead with the velocities of SIM-X, that means the pressures would be 2X to 3X greater than the structural design of the barrel; therefore, a catastrophic failure would occur. All SIM-X products’ pressures are within SAAMI specs. Furthermore, having a malleable core allows the projectile/bullet to pass through the barrel with greater ease.
What Is the Difference Between Clear Ballistic and FBI Gel Block?
Clear ballistic gel is a perfect marketing medium to replicate lead ammunition ballistics; however, the true FBI gel block is the standard for real world ballistics. SIM-X ammunition—specifically the DEFENSECORE™ products—do not react the same in clear ballistic gel as they do in true FBI gel block. Example: the 45 ACP DEFENSECORE™ will fragment within the clear ballistic gel, but will expand and stay intact within the FBI gel block.
What Is the FBI Ballistic Test Protocol?
The FBI Ballistic Test Protocol was developed over three decades ago and continues in use today, primarily for law enforcement agencies. Many of the civil defense ammunition does not meet the FBI protocol and nearly every lead-free ammunition fails to meet these standards. However, due to lead restrictions and increasing lead-free laws, more cities and county municipalities are departing from lead, along with the FBI protocol.
