Savannah, GA –-( 150 years ago hunters and shooters sat around campfires employing the time honored process of casting bullets for use during the next day’s outing.

Fast forward to 2015, that casting process of old has evolved into the PolyCase Ammunition way – a proprietary, technically advanced and fully automated injection-molded process.

Over the last five years Paul Lemke and JC Marin, along with the PolyCase Ammunition team, have tirelessly worked to develop this innovative technology that delivers accurate, lightweight, and reliable ammunition free of lead and the grey waste and heavy metal waste streams present with traditional manufacturing methods.

Founded by Lemke and Marin, the Savannah, Georgia based PolyCase Ammunition cut its proverbial teeth producing injection-molded precision parts from cutting-edge materials.

Lemke, a retired Army Ranger, had seen first-hand the need for smarter ammunition–from soldiers on the battlefield to civilian shooters and Law Enforcement personnel–and recognized the inherent possibilities present in the injection-molding process.

“From Formula One engine parts to ammunition, we are a precision injection molding company at heart,” said Lemke.

“Because we are approaching ammunition from a different angle, and own and control the research, development, prototyping, testing and manufacturing processes from the drawing board up to the finished product, we are able to carefully consider and determine all aspects of how our products are made to how they function.”

Using a proprietary lead-free copper alloy with a high-tensile strength nylon binder, PolyCase Ammunition Cu/P bullets and cartridges reduce weight, eliminate corrosion and cost less than traditional ammunition, and stand as a true game changer in a 140-year-old industry that has shown little innovation in manufacturing methods.

    1. I have shot the 9mm and 380 out of pocket guns and i was very impressed with the way they performed. There was noticable recoil reduction in my nano. The 380 doesnt have much anyway but the bullets performed well in a broken in glock 42- there has been some issues with new 42s and Fte’s. I am not a balistics expert but damage to hogs with the 9mm is impressive and with a 458 socom i imagine you would already have the sausage made. The arx bullet churns the flesh and fluids redirecting them into a damage inducing fountain of incredible force. I dont think the gel tests do it justice unless you get one in super slow mo and can see the channel being formed its impressive as hell. For me the 380 is a no brainer having been convinced that ball ammo was best for 380s because of the lack of power these bullets changed my mind they performed very well in the gel.

    2. From what I have seen of the results it appears as if the bullets go through hard substances directly ,but when in soft tissue they start to tumble causing a large wound area. They go end over end!!

    3. Does the bullet retain rifling marks from the barrel? Is the spent bullet traceable to a specific firearm and can it be compared to a lead bullet for forensic purposes? I would really like to know this, if not on this forum then in company literature.

    4. I just read the shot show report written in Guns&Ammo magazine. I’ve not seen or tryed this ammo but stand by the old saying, believe nothing you here and part of what you see. By what was in the article, it stated that it was very fast, and gave consistently large cavity with up to 12 to 14 inches. Giving up all energy dump in that space. ( This is what’s reported in the story). I’m old school ands always thought the , bigger, heavier, faster the better it was. I also believe in looking for something better. I agree with some of the thoughts posted but disagree with others. I don’t mean to be a know all, or smart ass but I’ve been shooting for 55+ years went through many a rounds, played with wildcat hand loads, some very hot ones. This stuff may or may not be the new wave of ammo, as some stated it needs to have more test trials before JUDGMENT IS PASSED. I’m not saying it will work or not but IF it will give the cavity and depth in flesh to do the job of stop danger then it may have a place on the market. If it explodes on contact, its NO, back to the lab . Line of though the first airplanes were a far cry from today’s jet.

      1. Well said sir–if we kept this “no new fancy technology,” attitude we’d still be using muskets. Some of the things people are saying here remind me of the things people said about polymer pistols back in the 80’s—“Not metal, it’ll never work!!!!” Wait and see if it bears out or not, sure there have been duds in new ammo types, but something new is going to work eventually. I’m willing wait a see what actual testing shows.

    5. Take a walk down any major roadway and look at all the lead wheel weights in the gutter. I walk from 2 to 4 miles at lunch every day and retrieve between 1/2 pound and one pound of lead wheel weights per day. And they are worried about lead bullets?

    6. Elemental lead is not the form of lead that produces all of the negative effects – lead acetate and other alloys are very toxic to humans and animals. Look it up.

    7. Think I’ll pass, don’t much like the idea of trying to clean a build up of plastic out of my barrel, copper is bad enough, plus they seem lacking knock down power, sorry think your on to a loser.

    8. Guys. I am a FFL in south Florida. There’s this new ammo called Libery civil defense that I have in stock. It’s aluminum ammo and it’s super fast and light. 9mm is 2000 feet per second, the 10mm is 2400 feet per second. The 45 is 76 grain and shoots 1900 feet per second. That’s crazy. It literally explodes on impact. Like a grenade. I will be writing a blog about the benefits and I carry this in my guns. It can go through walls, car doors, 2×4. They shoot a ham and the hand
      Blow up. Lighter ammo is the way it go!

    9. Leak toxins into the ground? Would that be the same ground that the lead was mined in the first place? Lead comes from the ground…How is it that people forget that when they talk about the toxicity of it? Because enviromental whackos have brain washed you into thinking that somehow lead is this evil thing that has no place in modern daily life…The truth is that lead is one of the only materials that is worth a crap for making projectiles…In order to maintain the kinetic energy stored in it, a projectile needs to be made from a heavy, dense material. These hybrid bullets made from copper and plastic lack that ability…and therefore do not have the power to stop an attacker…In other words they might be great for target practice but they are garbage for self defense…

      1. Please cite your sources. Darn near any thing in toxic/ or deadly in too large an amount. Heck you drink too much water at one time and that can be deadly. Not saying you are wrong but show me some hard data.

      2. Your point, Hemlock come from a plant that come from the ground, Mercury comes from the ground, I’d love to see you drink a glass of that stuff. Comes from the ground–can’t be toxic!?!?!

    10. First off “We the People” need to understand what the lead ban is all about!
      1. Lead is not poisonous and is a natural substance to any life form.
      2. Lead is cheap to mine and easy to form.
      3. Place one copper penny in a fish tank with fish and every life form will die within 24 hours.
      4. Fill the fish tank with lead and fish and observe that nothing will perish no matter how long you leave it.
      5. All the studies about lead poisoning are lies yet “We the People” fall for the deceit.
      6. In conclusion this false research is not about protecting the wildlife or people rather this is another attack on “The Second Amendment” to make self reliance unaffordable.
      This is my conclusion and after taking the time to check the research “The fix is in and We the People are nothing but serfs! If we wish to protect our environment believe none of what you hear and only half of what you see! Lead is the only mineral in the bullet which is SAFE FOR THE ENVIORNMENT. We are all being DECEIVED!

    11. Questions.
      1. How is material build-up in barrel compared to lead, copper plated and especially sabot. I get much more build-up from shooting saboted bullets in my front stuffer. Would suspect similar results from any polymer. Do they make a special solvent to address this?
      2. Has the penetration of balistic clothing been researched? Remember back in the 80’s when all the teflon-clad bullets were declared ‘cop killers’ and pulled from the market?
      I think they may be useful for some applications if the performance (both physical and terminal) and Price warrant.

      I’d like to see further developement and results.


    12. Looking at their published 9mm performance?
      That’s a big ol’ “No thank you.”

      Probably be OK for some applications – I certainly don’t object to the market deciding if these are a good thing or not – but I don’t see anything that *I* want to use them for.

      And as far as claiming that “they’re cheaper” when in fact they’re absolutely not?
      Regardless of the marketing strategy and/or a need to recoup their costs, *that* claim is *at a minimum* deceptive, and at worst an outright lie.

      I know all about the need to recoup their costs R&D, and tooling etc., but if they are dependent on a fast happening “large acceptance by consumers” and eventually a large recurring user-base, they’re VERY definitely going about it completely wrong.

      I’m going to slip on my Great Karnak turban and predict that barring some marketing change and plenty of evidence that they work REALLY WELL, that these will be a flop.

      Here’s why, right off the top of my head:
      1. The “marketing to cost” claim is false; they’re not cheaper
      2. The lightweight projectiles lose velocity/energy fast. Could be a plus, could be a minus, but it needs to be clear.
      3. There is no data or even testimonials about how accurate their projectiles are, either in general or as custom loads..
      4. There is one 37 second video of their 9mm in ballistics gel. How does this compare to other projectile performance?
      5. Nylon + copper in a hot barrel? Is the plastic going to soften/melt shooting long strings of fire? Does environmental and/or chamber heat affect accuracy?
      6. Is there enough recoil energy to reliably operate all the common blowback semi-auto pistols? The website is uninformative.

      I could keep going… I do wish these folks well, but if they want to put a supposedly new & disruptive technlogy out into the market, they’re absolutely going to need to provide very some solid bona fides.

      1. The dirty little secret about lead is that it isn’t. After years of the EPA and State agencies crying about lead poisoning Eagles etc they now find that the Bald Eagles really weren’t poisoned, the “science” was faulty and lead bullets and shot really had no effect except to be far better for waterfowl hunting than steel. Once again political agendas caused a furor to solve a non-problem.

        1. Ditto–Sources please. If you are going to shoot down ‘science’ as you say, then give us some proof–I’ll even go so far as to ask fro something subject to peer review–when it come to ‘science’ Guns and Ammo is not a credible source–sorry

    13. Sorry but I am not going to spend 95 cents/rd just to cut ammo weight in half. I’ll stick with my reloadable brass until the cost of polymer ammunition drops down to 20 cents/rd.

      1. It’s also newer technology and they need to recoup their R&D costs. Typical business model. Once it gathers steam, they can refine the process and reduce their profit margin as volume sales increase. All it needs is people willing to spend the increased dollars at the start.

      2. I hope the industry does not get into gouging the public since they are the only game in town. I get enough of this from the hoarders selling 22 ammo for a real stupid price. $30 for 25 rounds seems a bit high since the injected process is cheaper to make. I don’t pay anywhere near that for my (9mm, or 40) cal. and with those I get 50 rounds.

    14. Unless they find a way to make these expand like hollow point bullets they will never be anything more then practice ammo for anyone that knows ballistics. They will just not have enough stopping power. FYI part of the latest budget was a rider that took away the epa’s ability to try to do anything about lead ammunition.

      1. Good morning Halftine

        Re: “Unless they find a way to make these expand like hollow point bullets they will never be anything more then practice ammo for anyone that knows ballistics. They will just not have enough stopping power.”

        One of the interesting things about this design, is that it creates large temporary cavity as it spins into soft tissue, and THEN, by design, it starts to tumble. So ,now, you have the entire lengthwise size of the bullet turned SIDEWAYS or tumbling end over end transferring the energy rather than the diameter.

        This tumbling is built into the bullet by design…
        Now, mind you, I am not pushing this stuff, but have looked at it.

        It is indeed “out of the box” thinking about what we are trying to do with a round in the first place and how to do it with the modern methods we now have.

        Have a great day.
        God bless

      1. From an analytical standpoint, i’d say that this ammunition is more geared towards penetration than impact energy (knock-down power). Traditionally powerful rounds such as .45 ACP, .44 magnum, .454 using this material would likely perform closer to a 9mm’s ballistics. If it’s cheaper than traditional lead ammo, you can probably keep your current firearms (if you use these), and still remain effective, albeit in a different form. This may also reduce the gap between calibers in terms of lethality, by narrowing the range in effects on the target.

        Personally, I see this as more for target shooting with your existing guns, rather than having to use a bastardized weapon like a Ruger 22/45 to train your 1911 accuracy using cheaper .22 ammunition.

        1. Go to the Ploycase Youtube page a look at the videos of how they perform through various barriers and into ballistics gel. One of the primary components of “knockdown” power is hydrostatic shock. The wound channels in the videos are very impressive.

    15. But is it biodegradable? And if not, is that something that could be achieved? Just curious. Don’t get me wrong I am not a tree hugger or environmentalist.

      1. Lol…you’re saying it like being an environmentalist is a bad thing. I think if you are a hunter, you should be one, in a way.
        To your question: No, the alloy used is not “biodegradable” in a sense, like paper. But it will also not leak toxins into the ground.

        1. You both are confusing, or falling for the modern terms, for way used to be simply conservationists. The nut jobs have co-opted what used to be a Conservative idea into their NEO Statist agenda which is rooted in the hatred of conservatism. So from that they had to disrupt and distort everything that was proper and worked into something that is counter productive and failing. So your typical left wing politics 🙂
