Hornady MonoFlex ML .50 Caliber Low Drag Sabot ammunition is a muzzleloader projectile system consisting of a .452-inch-diameter MonoFlex bullet housed in a low-drag sabot. Designed for compatible .50-caliber inline muzzleloaders, this 20-count package uses a 250-grain monolithic copper-alloy projectile with Hornady’s Flex Tip technology.
The MonoFlex bullet is constructed from a copper alloy rather than traditional lead-based materials. Hornady states that the monolithic construction is designed to maintain projectile integrity during impact, with the bullet retaining approximately 95% of its original weight. The Flex Tip is incorporated into the nose of the projectile and is intended to promote controlled expansion across a range of impact velocities, including lower velocities associated with longer-range impacts.
The .452-inch projectile is paired with a Low Drag Sabot engineered for use in .50-caliber muzzleloading systems. The sabot provides the interface between the projectile and the bore, allowing the smaller-diameter MonoFlex bullet to be used in a compatible .50-caliber muzzleloader. As with all muzzleloader components, compatibility should be confirmed with the firearm manufacturer's specifications before use.
Hornady lists the MonoFlex ML for medium game weighing approximately 50 to 300 pounds. The projectile has a listed sectional density of .175 and a ballistic coefficient of .210 (G1). The product is supplied as 20 individual 250-grain projectile-and-sabot combinations under item number 67274.
Published ballistic data was developed using a stock Thompson/Center Omega inline muzzleloader with a 150-grain powder charge. Hornady lists a muzzle velocity of 2,250 feet per second and muzzle energy of 2,735 foot-pounds. At 50 yards, velocity is listed at 2,031 feet per second with 2,290 foot-pounds of energy and a trajectory of 1.8 inches. At 100 yards, the listed velocity is 1,852 feet per second with 1,904 foot-pounds of energy and a trajectory of 3 inches.
At 150 yards, velocity is listed at 1,574 feet per second with 1,684 foot-pounds of energy and a trajectory of 1.7 inches. At 200 yards, the published velocity is 1,529 feet per second with 1,297 foot-pounds of energy and a trajectory of -2.7 inches. At 250 yards, velocity is listed at 1,389 feet per second with 1,070 foot-pounds of energy and a trajectory of -11 inches.
