Our Ammo
What does Polymer-based even mean? Is it rubber? Plastic?
No. PolyCase ammunition has implemented injection molding technology and cutting-edge engineering to create a proprietary metal/polymer compound. The ARX® is injection-molded from a proprietary copper and a high-tensile strength nylon mixture. This process allows us to create designs that make precise, consistent, accurate, low ricochet, lead-free bullets with sound terminal performance..
The ARX® looks like it is designed to rotate in one direction. Will the ARX® work in a left hand twist barrel?
Yes. The ARX® is designed for maximum effectiveness out of a RH twist barrel, but the truth of the matter is that it works almost equally effectively in LH twist.  In fact, the difference is immeasurable in all of our terminal ballistic (gelatin) testing. This is because the bullet’s rotation is actually a nominal factor in the energy transfer mechanism.  Instead, energy is transferred to the target by the shape of the radial flutes, which serve to pressurize and redirect fluid matter laterally regardless of the twist direction of the bullet.
Does the fluted nose of the ARX® bullet cause any issue for stable bullet flight?
No. The bullet spins in the air at the same rate and no differently than a traditional projectile.  The bullet nose creates a pressure cone during supersonic flight so the grooves do not affect rotation or bullet stability in air.
How does ARX® stand up in lab tests?
Our ARX® cartridges have been independently tested by Dayton T. Brown, Inc. (DTB), the largest independent test laboratory in the world. DTB tests ammunition for the Department of Defense and major ammunition manufacturers. Test results like high speed photography of gelatin block shots show that the ARX® transfers force to targets in a completely new way. Through rotational and lateral transfer of energy, it produces large temporary cavities.

Is PolyCase lead-free?
Yes. We use copper as the primary metal in the ARX® because it is easier to work with in injection molding than lead. (As an incidental benefit, the bullet is non-toxic.) We are also fully range compliant, making this ammo the perfect choice for those states dealing with the associated costs of cleaning up leaded ammunition.
I compete professionally. Is this ammo good enough for competition?
Absolutely. It’s ideal for competition on several fronts: weight, accuracy and performance. Several pro shooters say this will revolutionize the ammunition industry. The list of pros using Polycase grows every day. Once they try it, they’re hooked.
Is Polycase law enforcement and military grade?
Yes, its heritage was born out of real-world military experiences. Polycase manufactures ammo for certain law enforcement and military agencies and the civilian consumer market.
Why should I give up my current hollow point self-defense bullet for this?
We’d never tell you to give up your favorite bullet. We believe we can make a case for ARX®. Once you try it, it just might become your new favorite. Why? Maximum force combined with reduced recoil. The Inceptor® ARX® and Ruger® ARX® lines of ammunition by PolyCase® transfer force as effectively as competing lead-core expanding hollow point rounds.

Since it doesn’t rely on expansion to transfer energy, the ARX® can’t fail to expand like some hollow-points either, nor does it get hung up on feed ramps. And, even though some ARX® cartridges carry more energy out to the 15-yard practical limit for self-defense situations than hollow-points, they have less felt-recoil and muzzle flip, allowing for quicker follow-up and higher accuracy over multiple shots.

What’s the deal with the arc shape?
The unique arc-shaped grooves in the profile of the ARX® are a perfect blend of form and function, and essential to its performance. These ‘flutes’ act to harness both the rotational and directional energy of the bullet as it impacts a semi-solid target (gelatin, or a deer shoulder, for example).

While the flutes have no effect on the ARX® aerodynamically, and thus do not affect accuracy, they grab onto semi-solid or fluid targets to redirect the bullet’s forward energy laterally. This creates the large temporary (wound) cavity you see in our gelatin block photos, and results in the complete transfer of energy to targets that makes this an effective self-defense cartridge.

Why should I choose a metal-polymer bullet over a traditional bullet?
The metal-polymer bullet incorporates both metal powder and an epoxy resin, and it’s the way we’ve put them together that makes it unique when compared to conventional ammunition.  The ARX® is injection molded from a proprietary metal and high-tensile strength epoxy mixture.
Can I store it like my other ammo and expect it to work the same?
Why is lighter better?
Think of it in terms of energy, not just weight. The Energy of a bullet is a function of its Mass and its Velocity. On average the ARX® weighs about 2/3 the weight of comparable lead-core bullets, allowing it to be fired at a much higher velocity. In total, the ARX® bullet is designed to carry more Energy during the first 15 yards than any slightly heavier competition. And when it comes to carrying extra ammunition, be it competition or otherwise, lighter means you’ll be able to carry more.
Lighter and faster is one thing, but I need stopping power. Does this ammo penetrate?
And then some. If you’re using a gun in self-defense, chances are you are engaged at a distance of less than 15 yards. The ARX™ is designed to balance the need for damaging penetration with complete transfer of kinetic energy (to ensure the target gets the full blow from the bullet).  Just take a look our gelatin block tests, which show temporary (wound) cavities that rival those created by the leading hollow-point bullets.

We’re not about big shallow entry wounds that cause superficial damage, the ARX® is designed to cut into and penetrate to a significant wound depth and cause massive hydrostatic shock damage through cavitation along the way. The ARX® creates temporary (wound) cavities that rival other bullets in the same caliber.  When the bullet encounters dense bones it fragments, creating multiple wound channels.

What about over-penetration?
With high-velocity comes another real concern: over-penetration. The ARX® is specifically designed to harness the forward energy and turn it into maximum damage to targets. The fact that the ARX® bullet stops within 16” of entering a properly calibrated 10% ballistics ordnance gelatin block means it is dumping 100% of its energy into its target, not innocent bystanders.
Why doesn't the ARX perform in synthetic gelatin?
The industry standard is 10% ballistics ordnance gelatin and “everybody” (writers and “aficionados”) know that and are skeptical if someone uses a substitute to 10% ballistics ordnance gel.  Clear gel is not an ordnance gel replacement…. and using it with the fluid displacing ARX® bullet will create results that are like comparing apples and rocks.

What makes Polycase more than just the flavor of the week?
We’re bringing some new technologies to a very old industry. The basic method for making bullets (cast lead, or lead core with copper jacket) has been around for over 100 years. Recent advances in expanding bullet technology have created some very potent self-defense rounds, but most still rely on the expansion effect to transfer terminal energy.

That’s where we come in: Our technology is the result of cutting-edge  scientific research and development, but it is grounded in fundamental, well-understood physics. We are just the first company to develop a manufacturing method that allows us to harness these principles in a mass-produced, affordable product.

Is this a frangible round?
Our ARX® and RNP® are frangible on hardened steel and fragmenting against dense bone (akin to a jacket being ripped off of a hollow point that encounters a femur) and certain intermediate barriers. Frangibles are bullets that break up into pieces, none of which total more than 5% of the total weight of the original bullet, upon impact with hardened steel.

What does this mean beyond the controlled environment of ballistics gel and labs? Our bullets achieve solid performance at close distances through certain intermediate barriers like drywall or denim.  They also penetrate but fragment through major barriers such as glass or some types of steel, but they are unlikely to over-penetrate through multiple such barriers. Simply put: It’s less likely to go through your walls and into your neighbor’s house.

What does this mean for the future of hollow-point technology?
As we mentioned above, hollow-point technology has seen some amazing advances in the last 10-15 years, and we love to see other manufacturers push the limits of what works in ammunition. That said, hollow-points will always rely on the expansion effect to transfer terminal energy, and expanding bullets have some inherent disadvantages (clogging and failure to expand, feed ramp sticking, loss of retained weight after impact, etc.).  The ARX® is based on advanced materials and engineering, tested using standard ammunition testing protocols, and produced using a manufacturing method that allows us to put it on shelves at affordable prices.
