This is .223 Hornady LE 62gr. TAP Barrier Ammo. Unique tactical situations demand ammunition with unique qualities and Hornady’s TAP Barrier ammo is one of the most specialized cartridges ever developed. The TAP Barrier round was initially designed to meet the specific need to penetrate steel doors and deliver terminal performance on the opposite side. Hornady originally developed this ammunition to meet the requirement for a high-speed, barrier penetrating bullet that could be used for nuclear power plant security. The design of the TAP Barrier round allows the projectile to maintain its structural integrity while punching through barriers, yet initiate expansion in soft tissue. For patrol carbine programs or any tactical situation where the need is for accuracy, barrier penetration, and terminal soft tissue expansion, Hornady’s TAP Barrier ammunition is the ideal choice. This ammo is packed in 20rd. boxes.
