Ballistic Tip Lead-Freeâ„¢ Bullet The Ballistic Tip Lead-Freeâ„¢ (BTLF) is everything that varmint and predator hunters expect from a Ballistic TipÂ®, in a lead-free design. The flat-based, lead-less bullet features Noslerâ€™s exclusive Fragmenting Copper Core Technologyâ„¢ (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 TipÂ® has made famous for more than 25 years. Ballistic Tip Lead-Free bullets are offered at the same MSRP as standard Ballistic TipÂ® bullets in 100 ct. boxes.
