With its unique cross-member copper jacket design and a bonded front core, the A-Frame has become famous for its ability to combine 3 performance features - controlled expansion, deep penetration and 95% weight retention at all velocities. From tip to base, the A-Frame features a soft, semi-spitzer lead nose protects it against felt recoil while in the magazine. Next, the pure copper jacket begins to taper around the pure lead core at the tip of the bullet in an effort to help control the expansion rate at a wide range of velocities. The core towards the base of the bullet is where the momentum for the deep penetration comes from. The wrap-around jacket on the base of the bullet helps retain the bullet's original weight and prevent deformation. This is not loaded ammunition.
