Miami, Florida (Ammoland.com) National Police Ammunition (NPA), the world’s leader in lead free ammunition, is pleased to announce the development and soon to be released patent pending HELO SR 9mm 120 grain solid copper hollow point with a sintered alloy fluted ballistic insert.  HELO SR is an acronym for High Expansion, Law Enforcement, Ordinance with a Sintered Ram.

The NPA Patented Pending HELO SR is designed for law enforcement and specifically to pass and exceed all FBI performance protocols.

NPA patent pending SR ballistic insert utilizes a metal alloy sintered tip that will not deform in flight and acts as a barrier blind round by allowing the ballistic tip to defeat intermediate barriers then release from the main body of the projectile once encountering soft tissue allowing complete energy transfer and controlled expansion of the main body of the hollow point bullet mitigating risk of over-penetration.

The patent-pending sintered alloy fluted insert is much denser that other products on the market that use a polymer, nylon, or a plastic material giving the HELO SR greater ability to stay intact when passing through FBI protocol barriers such as auto glass, steel, plywood, and drywall.

Once the bullet encounters soft tissue a hydraulic effect is created when entering the cavities between the flutes thereby forcing the bullet to expand and releasing the ballistic insert from the main body of the hollow point.

NPA will first introduce the HELO SR pistol cartridge in the increasingly popular 9mm among law enforcement and will be expanding the line to all other major calibers.

There are two variants developed of the HELO SR one being restricted to the law enforcement market and a second designed for civilian self-defense distributed by NPA’s commercial brand Alchemist Ammunition.

    1. atf is the threat that is clear, it is up to people to show atf we will not do as they ask, i am currtly filed two formal complants agest the atf, and bouth of the sentors has taken it on, i refuse to back down and when a atf lawyer refuses to awaser a simple quistion then they all ready broken the laws, i to will be going after others if i get this law firm to take a bite of the acton i wont stop with just money i want crimal actions filed, will be firsr time and dont madder how far i get just that never been done and i have try

    2. Who in their right mind would ever turn in the guns? If you don’t turn them in and your caught with them your a felon. Oh freakin well. The threat of that will just make many people into cop killers in my opinion. If I were law Enforcement I doubt I’d be following any orders to confiscate any weapons. You kick in that door mr. politician, let’s see how well you fare after word gets out. LOL

    3. There is already a round made that is similar in the dynamics of it. It will go through drywall, plywood, car doors or glass windshields without expanding. Once it enters soft tissue it expands. I was looking at it over the weekend and almost decided to order some of it. Too expensive to shoot much of it at the range though. It was in the range of about $1.75 a round. I wouldn’t trust it for defense purposes without trying some of it in my carry guns first. There are so many high priced gadget rounds out there today. Maybe the manufacturers will send some of it to the poor folks like me for a sample.

      1. my 50 cal ar u vest becomes useless u just die but building a lower to reduce recoil and reduce amout force put on bolt has been what i working on, so with a 400 doller trigger and spichle device that ack take foce off the bolt was install waiting on rest of the lower parts, a normal ar lower is not adviseable get the best parts

    4. I wonder what the price per round is. That will be the determining factor. If its priced around Federal HST then great. If its priced above the question is does it do the job whatever percentage better than HSTs and similar rounds to the HST

    5. Don’t cry about the latest and greatest. A .308 still hits hard when placed correctly. Cry about the billions of tax dollars we pay for leo/gov’t misuse.

      1. @Not, Oh they count you alright, and keep track, too. In fact, they are planning on using this ammunition on us. But it is ok because we will get the weaps and ammo from them, when and if we need it.

      2. Not really. We are only good for taxes. After that, easy to replace. Remember, LEGAL LAW-ABIDING AMERICAN CITIZENS are now looked upon as the worst of the worst.

        1. Keep the illegal undocumented citizens coming over the borders, with MS-13 infiltration along with other impostors/terrorists claiming to be children and you will have increased population without taxpayers.
          Keep up the good work lawmakers in Washington…Illegal Aliens first, American taxpaying citizens last…
          P.S. FMJ’s Work well also in times of haste. Proven time and time again in WWII battles..

          1. @RJL…Not to worry, after they out live their usefulness they all will be;
            Herded into camps ;
            Starved ;
            Gassed or shot ;
            Shoved into mass graves :
            And it will no longer matter if you are (were) a citizen , lawyer , illegal , baker or indian chief !
            Check your history …Venezuela is well on the way .

            1. Socialism>Communism>Gun Control=Disarmament=Extermination…

              A LITTLE GUN HISTORY
              In 1929, the Soviet Union established gun control. From 1929 to 1953, about 20 million dissidents, unable to defend themselves, were rounded up and exterminated.
              In 1911, Turkey established gun control. From 1915 to 1917, 1.5 million Armenians, unable to defend themselves, were rounded up and exterminated.
              Germany established gun control in 1938 and from 1939 to 1945, a total of 13 million Jews and others who were unable to defend themselves were rounded up and exterminated.
              China established gun control in 1935. From 1948 to 1952, 20 million political dissidents, unable to defend themselves were rounded up and exterminated.
              Guatemala established gun control in 1964. From 1964 to 1981, 100,000 Mayan Indians, unable to defend themselves, were rounded up and exterminated.
              Uganda established gun control in 1970. From 1971 to 1979, 300,000 Christians, unable to defend themselves, were rounded up and exterminated.
              Cambodia established gun control in 1956. From 1975 to 1977, one million educated people, unable to defend themselves, were rounded up and exterminated.
              56 million defenseless people rounded up and exterminated in the 20th Century because of gun control:
              You won’t see this data on the US evening news, or hear politicians disseminating this information.
              Guns in the hands of honest citizens save lives and property and, yes, gun-control laws adversely affect only the law-abiding citizens.
              Take note my fellow Americans, before it’s too late!
              The next time someone talks in favor of gun control, please remind them of this history lesson.
              With guns, we are “citizens”. Without them, we are “subjects”.
              During WWII the Japanese decided not to invade America because they knew most Americans were ARMED!
              If you value your freedom, please spread this anti-gun-control message to all your friends.

          2. Agreed about the FMJ’s working well. I am amused when they are sold as “target” ammo. I figure that anybody trying to kill me is a target.

      3. It’s all about the money. They probably want those sweet sweet government contracts. All at the taxpayer’s expense, mind you, to, you know, keep you safe and all that.

        1. Your ammo looks interesting and if it works as claimed good on you but unfortunately it is just a matter of time till they change the pistol armor piercing laws to cover your bullet as well and for the DYIers out there they will make it a crime to be in possession of AP pistol ammo as well.
