This expert-level analysis from Tools&Targets compares subsonic 9mm and .300 Blackout ammunition for home defense. The video details a rigorous ballistic gel test, including chronograph readings, wound channel analysis, and projectile recovery. The instructor, demonstrating significant expertise, concludes that while both perform well, the 9mm T-Series offers superior expansion and penetration in this specific short-barreled configuration.
Subsonic ammunition travels below the speed of sound (<1100 fps) to eliminate the sonic crack, making it ideal for suppressed shooting. While offering reduced recoil and quieter operation, subsonic rounds often require heavier bullets and specific barrel twist rates for stabilization. Semi-automatic firearms may also face cycling issues with lower-pressure subsonic loads, making certain platforms like bolt-action rifles or .300 Blackout ARs more suitable.
This TGC News episode covers several new firearm releases and industry updates. Highlights include the American-made Palmetto State Armory AK-103, the Sig Sauer P938 SAS with its unique FT Bullseye sight system, and innovative products from IWI and Essential Holsters. The segment also touches on significant ammunition contracts for Hornady and Speer, and a change in ownership for Heckler & Koch, offering insights into current market trends and product developments.
This expert-level review by TFB TV details a ballistic gel test of Hornady's 190gr Sub-X .300 AAC Blackout subsonic ammunition. The test, conducted with an 8-inch SBR, analyzes expansion and penetration through bare gel and heavy clothing. The instructor concludes that subsonic .300 BLK is generally less effective for self-defense than supersonic loads.
