Hornady combined technologies from the GMX and FTX bullet designs to create MonoFlex rifle bullets, which provide non-toxic, pointed-tipped projectiles that are safe for use in tubular magazines, as well as all actions and magazine types. MonoFlex bullets utilizes Flex Tip rubber/polymer tips that enhance ballistic coefficients for flatter trajectory, and help initiate expansion of the solid copper alloy core. Bullets also feature a sleek secant profiles to further enhance flat trajectory. Solid copper alloy construction eliminates the chance of jacket/core separation, and retain 95% of original weight for deep penetration. Copper alloy construction is hard and tough, and does not foul or increase pressure the way 100% copper bullets do. Aerodynamic Hornady MonoFlex Rifle Bullets dramatically extend the range of cartridges normally loaded with round- or flat-nosed bullets. Made in USA.
