Harvester Muzzleloading Crush Rib High Pressure Sabots provide the carrier needed to load .451- or .452-inch diameter bullets in a .50 caliber muzzleloader. This exact black configuration is supplied as a 50-count pack of sabots, allowing muzzleloader shooters to pair a compatible projectile with their preferred rifle and an appropriate published load. Bullets are not included, so the shooter can select a suitable .451- or .452-diameter projectile for the intended range, hunting, or load-development application. Each sabot surrounds the smaller-diameter bullet so the assembled combination can properly engage the larger .50 caliber bore during loading and firing. The distinctive Crush Rib exterior is designed to reduce loading friction by up to 50 percent compared with a conventional smooth sabot, which can make seating the projectile more manageable while maintaining the fit needed for consistent use. This design is particularly useful for shooters who assemble their own muzzleloader projectile combinations and want the flexibility to test different compatible bullets without purchasing complete prepackaged bullet-and-sabot sets. Harvester identifies this model as a high-pressure sabot and engineers it to operate within standard muzzleloader loading specifications. Because muzzleloader bore dimensions and individual bullet combinations can vary, the final fit should be checked in the specific firearm before field use. Shooters should always follow the firearm, projectile, propellant, and ignition-system manufacturers' published loading instructions rather than substituting untested load data. The patented Crush Rib design is manufactured in the United States to Harvester Muzzleloading's specifications. With 50 sabots in the package, this exact variant offers a practical supply for range testing, sight-in sessions, load development, and preparation for muzzleloader hunting seasons when paired with an appropriate .451- or .452-inch bullet.Specifications and Features: For .50 caliber muzzleloaders Accepts .451-.452 diameter bullets 50 sabots per pack Black Crush Rib configuration Ribbed design reduces loading friction up to 50% High-pressure sabot design Patented by Harvester Muzzleloading Made in the USA Brand: Harvester Muzzleloading Series: Crush Rib Product Type: Muzzleloader Sabots Manufacturer Part Number: H15045BR
