This ammunition revolutionizes subsonic hunting in the .300 AAC Blackout caliber. In the past, the terminal ballistics of subsonic ammunition, including the .300 BLK, have been limited in respect to knock down power and wound channel size by projectiles which did not expand. Engel Ballistic Research’s new .300 BLK "Phantom" Subsonic Expander maximizes the transfer of energy on live targets exponentially by utilizing a projectile which dramatically and rapidly expands on impact with soft tissue creating a large cavitation while at the same time cutting through live tissue in a way similar to a broad head on an arrow.
"I was able to harvest this 8 point whitetail using the .300 BLK "Phantom" subsonic expander out of my Spikes Tactical short barrel suppressed .300 BLK. He walked right up on my ground blind and was only about 20-25 yards when I hit him on his right side. He dropped & crawled in a circle but never made it more than 5 yards. When cleaning, we noticed the bullet hit his right side behind his shoulder, expanded & traveled through chest cavity lodging on the inside of his opposite shoulder blade. I was very impressed with the knockdown power, quiet sound, and smooth cycling with these rounds."
