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.

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… Read more »


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!!

Doug Gerber

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.


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… Read more »


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.


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?


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.


If you think lead is non-toxic, you are an idiot


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.

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… Read more »


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… Read more »


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.


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!?!?!

How will it work in my auto loaders Springfield Armory 1911A1NM and M1ANM? .45 and 7.62NATO respectively.


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… Read more »

If I could by bulk bullets cheaper than buying or making lead bullets I would try them in handloads. In the meantime lead is much cheaper to use.


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.… Read more »


Are there any deposits left in the barrel? If so how what solvent would be used?


I would like to try some of these, where can I find them?

FirstFreedom has them in stock, $29.99 a box. I’m sure others have them, too, but I just saw them on their website.


Sounds good to me. Lead is dangerous to humans and animals. I would rather kill them with expanding and exploding bullets over lead poisoning any day 😉




They look like brass casings don’t they?? If they are what they look like then they most certainly can be reloaded!


I keep seeing cheaper, but no prices listed at all, no load data listed either.


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… Read more »

Does it have the mass of lead? Plastic won’t do.

Christopher Cherrone

How well does it perform in .308 semi auto? would like to try some in my handgun.

Jacob Wilkerson

This is sweet, I’m in..

Dirty Brown Dog

Lead and asbestos were also the greatest thing in the day and then years later …………… 🙁


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.

petru sova

Could you give me a link to some documentation on your claims. I would like to read more on this. thanks.


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


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.


Will these be able to reload? If not, what is the incentive to pick up the casings? Are they able to be recycled and repossessed?


keep me informed – im looking for a vendor in my area – north central indiana


They are 30$ box of 50 and lower velocity than standard ammo


You gotta love how the article claims the ammo is cheaper than traditional ammo, yet the company’s vendors are selling for $30 per 25 rounds.


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.


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.


Sign me up. I want to try this

mike barber

is this product biodegradable and isn’t available in California


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.


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… Read more »

Are you selling and shipping to Idaho addresses. 9 mm
And contact information please.


The proof will be in how the stuff performs. The Firearms Industry has a centuries old tradition of nifty ideas that don’t pan out.


I would like to give them a try and if they are cheaper just means more shooting for me lol.


I like 9mm due to ammo cost. Which one is cheapest?


Would they make it so people could buy these projectiles to reload


would love to try specially in 45 for weight/less weight. Also in 9mm, 45/70, 30.06

William OBryant

With it being lighter, will your ammo have the knock down punch that regular ammo has?


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… Read more »

john olson

where do you find “cheaper 22 ammo”? I can actually reload for my 44 mag cheaper than I can buy 22 LR ammo!


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.

Vito Buono

What are your caliber choices?


Would like to try some of these. Where can you get some of these to try out?

Judge Hayes

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.


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.


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 🙂
