Hornady CX Features Because this bullet is a single piece of copper alloy rather than a jacketed lead core it can t separate on impact the way traditional bullets sometimes do delivering consistent terminal performance and around 95 percent weight retention across a range of impact velocities. The Heat Shield tip is molded from a heat-resistant polymer engineered to resist the aerodynamic heating that degrades a standard polymer tip at high velocity keeping the bullet s .418 ballistic coefficient stable from muzzle to target. That same tip design also produces a consistent meplat shot to shot which handloaders rely on for tight repeatable groups. Optimized groove geometry cut into the bullet s bearing surface reduces fouling in the bore while maximizing aerodynamic performance letting handloaders shoot more rounds between cleanings without accuracy dropping off. Because the CX is entirely lead-free it meets the requirements for hunters in California and other regions mandating nontraditional projectiles. At 90 grains and built specifically around 6mm cartridges this bullet gives handloaders a serious lead-free option for medium game hunting without compromising on penetration or expansion.
