The Ballistic Tip Lead-Free 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.
