The Ballistic Tip Lead-Free (BTLF) is everything that varmint and predator hunters expect from a Ballistic Tip in a lead-free design. The flat-based lead-less bullet features Nosler?s exclusive Fragmenting Copper Core Technology (patent pending) which exhibits immediate and rapid expansion initiated by its metallic-colored polymer tip at practical varmint shooting velocities of 1600 fps and above. The BTLF can safely be used in all lead-free zones or shooting ranges that require non-magnetic bullets. Users can be confident of the same performance and quality that the Ballistic Tip has made famous for more than 25 years. Unique Metallic- Colored Polymer Tip: Nestled in the jacket mouth is the streamlined polymer tip color-coded by caliber. Ultra-Thin Copper Jacket Retains structural integrity at ultra-high velocities yet fragments completely upon impact Fragmenting Copper Core Allows rapid and absolute displacement of target Flat Base Ballistically engineered for ultra-high velocities and bench rest accuracy
