.300 AAC Blackout -220 Gr HPBT Subsonic (20 Count)

These subsonic cartridges are loaded with 220 grain HPBT and a powder that will still produce enough gas to cycle your AR. Mainly manufactured for use in suppressed weapons, these cartidges are perfect for anything from large hogs to self defense. All components making up these cartridges are match Grade and the cartridges have a high degree of consistency in testing. These cartridges were manufactured at True Ballistics, LLC in Kenedy, Texas using superior components and unmatched quality control processes. Each lot is tested for pressure, velocity and accuracy in our testing facility. This facility incorporates a 200 Yard underground test range to eliminate any variables that an outdoor climate may introduce to the projectile being fired down range, therefore giving us the ability to ensure that all results produced down range are as accurate and consistent as possible for customer use. The use of doppler radar, pressure and accuracy barrels, as well as high speed video in collaboration with the test range make for truly the most accurate and consistent results.
