The content, utilizing a Phantom V642 high-speed camera from Aimed Research, presents new test data that casts doubt on previous findings regarding its performance. Velocity data (average 2,204 fps, std dev 23.38) is provided, suggesting a need for reconsideration of its suitability for defense applications. The video is presented as an educational resource focusing on technical ammunition performance.

This test evaluates the Hornady 75gr BTHP match bullet for self-defense applications using a ballistic gelatin medium. Fired from a 10.5-inch AR-15, the bullet achieved 15.4 inches of penetration and exhibited significant fragmentation, creating a large temporary stretch cavity. While its performance was deemed 'devastating,' its potential lack of barrier penetration, common in match bullets, is discussed as a double-edged sword for home defense.

This expert-level knowledge entry details a ballistic gel test of Hornady TAP .223 Remington 75gr BTHP ammunition (#80265). The test, conducted by Mrgunsngear Channel, measured muzzle velocity at approximately 2980 fps and analyzed terminal performance in gel. The bullet maintained integrity until 4 inches, with fragmentation beginning thereafter and jacket separation at 10 inches. Fragments were found up to 19 inches, with recovered fragments weighing 3.3 grams (approx. 49 grains). The round is recommended for home defense due to its effective wound channel and fragmentation.
