Today at the ATK Industry Day, SSD was privileged enough to witness a demonstration of Federal Premium LE’s new Tactical HST round in .45 Auto. When fired into ballistic gel, which is designed to simulate human flesh, the round penetrated a full 12 inches (the photo was taken off angle), expanding to a max diameter of .96 inches at its resting point. The round is a two piece projectile with a copper jacket that folds completely out of the way during penetration, while the round’s petals open to full expansion. The ammo is available in 9mm, .40, .45, and .357 SIG, however the SIG round is too fast, and as a result doesn’t fully open during penetration. More information can be found at www.le.atk.com.
