Halo Ammunition as stated earlier has ballistic performance unlike anything else the industry has ever seen. We travel through over 18"+ of ballistic gel. To put that into perspective our competitors can test their ammunition by firing into a single ballistic gel block. We have to utilize two gel blocks to capture Halo's performance in the 9mm. When was the last time you could honestly say one just wasn't enough to handle what you have? The radius spread at which the spears detach themselves upon impact into gel exceeds 5". Giving more trauma and lethality to target.  So what about our accuracy? Well honestly, we thought originally back in the day we would be sacrificing some accuracy to get what we originally intended to do, but through years of testing our design just so happens to be the most accurate 9mm round we can find. We can place 4 rounds into a playing card at 50 yards from a 4" barrel. Again, what other defense/tactical 9mm round do you know that can do that? As a recap our 9mm travels at over 1350 Ft per second (411.5 m/s), comes in around 107 +/- grains (6.93 grams).  Accuracy of 2" group at 50 yards, fired from a 4" barrel (according to internal testing).
