Frequently Asked Questions:
Q: What are the key features of the Hornady Subsonic 300 Blackout 190gr SUB-X ammunition?
A: The Hornady Subsonic 300 Blackout 190gr SUB-X ammunition features a 190 grain Sub-X (Subsonic - eXpanding) bullet designed for accuracy and performance below the speed of sound. It has a muzzle velocity of 1050 fps, a ballistic coefficient of 0.437, and is optimized for use in suppressed firearms. The bullet has a patented Flex Tip insert and long grooves in its gilding metal jacket to ensure reliable expansion at low velocities.
Q: What is the intended use for this ammunition?
A: This ammunition is primarily designed for tactical and home defense applications using suppressed firearms. It's also suitable for hunting medium-sized game at close ranges. The subsonic velocity reduces noise and muzzle flash, making it ideal for situations where stealth is important. Its performance meets or exceeds FBI Protocol terminal ballistic test requirements, ensuring effective stopping power.
Q: Can this ammunition be used in both suppressed and unsuppressed firearms?
A: Yes, the Hornady Subsonic 300 Blackout 190gr SUB-X can be used in both suppressed and unsuppressed firearms chambered for 300 AAC Blackout. However, it's optimized for use with suppressors to maximize noise reduction. When used in unsuppressed firearms, it will still maintain its subsonic velocity and reduced muzzle flash, but won't be as quiet as when used with a suppressor.
Q: How does the 190gr SUB-X bullet perform in terms of expansion and penetration?
A: The 190gr SUB-X bullet is designed to expand reliably at subsonic velocities. In ballistic gelatin tests, it typically achieves 16-18 inches of penetration with 90%+ weight retention when impacting at 1020 fps. The bullet's design, including the Flex Tip and grooved jacket, helps ensure consistent expansion even at lower velocities, making it effective for both self-defense and hunting applications within its intended range.
