Are Polymer-Copper Matrix Bullets the Future for Pistol Ammo?

Take a good look at this unusual ammunition. We think you are looking at the future of handgun ammo — at least for range and practice work. This patent-pending ammunition features a 100% lead-free bullet blended from polymer (plastic) and copper powder. The polymer-copper matrix (PCM) composition offers three major benefits: 1. the bullets do not ricochet; 2. the bullets are lighter and therefore faster than conventional projectiles; and 3. the bullets are environmentally friendly. We think this is a big deal — we predict matrix pistol bullets will become extremely popular in the years to come.

At the 2016 SHOT Show Media Day, we shot ammo with PCM bullets in a half-dozen handguns. The ammo performed flawlessly, without a hitch. In .40 SW and .45 ACP pistols, the felt recoil was considerably less than with conventional lead-core ammo (the difference was less noticeable with .380 ACP and 9mm Luger).

Ruger is now offering Ruger-branded ARX ammo with polymer-copper matrix bullets. This ammo will be produced under a licensing agreement with PolyCase Ammunition, the Georgia-based business that originally developed this bullet technology.

While Ruger is touting this ammo as a self-defense solution, we think the most common use of this new ammo will be for indoor practice, plinking, gun games such as IDPA, and use on steel and reactive targets. If you like to shoot steel, matrix bullets make sense. The polymer-copper matrix bullet basically disintegrates into very small fragments when it hits metal.

This video includes extensive tests of Ruger 9mm ARX ammo:

The fluted projectiles are injection-molded from a polymer-copper matrix. This offers many advantages. First, being completely lead-free, these bullets can be used at indoor facilities that prohibit lead-based ammo. Second, because the composite bullets weigh 30% less than comparable lead-based projectiles, shooters experience less recoil (even though velocities are higher). Third, the composite matrix bullet has low-ricochet properties. When these bullets strike metal, they are designed to disintegrate, rather than ricochet. This makes them well-suited for indoor use, or use with metal plates.

Ruger’s new ARX line of lead-free ammo features injection-molded bullets that are much lighter than conventional projectiles, caliber by caliber: 56 grains for .380 ACP, 74 grains for 9x19mm, 107 grains for .40 SW, and 114 grains for .45 ACP. The lighter bullets fly faster, but ARX ammo still offers reduced perceived recoil.

Shooting Wire Editor Jim Shepherd reports that ARX ammo delivers on its low-recoil promise: “Having spent time testing the PolyCase ammunition (largely in Ruger firearms), I know the reduction in felt recoil isn’t just hype. While firing PolyCase ARX ammunition in calibers ranging from .380 in small concealed carry pistols (including a Ruger’s LCP) up to .458 SOCOM in modern sporting rifles, the lessened felt recoil was noticeable.”

Polymer-Copper Matrix Bullets Show Good Penetration
Despite their lighter-than-average weight, ARX bullets show good penetration in ballistics gelatin, thanks to their unique, fluted-tip design. This video shows penetration tests:
