Hornady Bore Driver Features The Hornady Bore Driver system replaces the traditional sabot with an integrated polymer base that seals the bore directly delivering more consistent energy transfer to the projectile than conventional sabot-based muzzleloader bullets. This sealing action reduces gas blow-by which translates into more consistent velocity and tighter downrange groups from shot to shot. The ELD-X bullet mounted atop the base features a rugged gilding metal jacket built to withstand the punishing pressures of muzzleloader ignition without losing structural integrity. Hornady s InterLock ring mechanically bonds the jacket to the core preserving weight retention as the bullet expands through heavy muscle and bone on big and medium game. Fast easy loading is a hallmark of the Bore Driver design letting hunters reload quickly in the field without struggling to seat a stubborn sabot. The polymer tip on the ELD-X bullet initiates expansion reliably even at the reduced velocities typical of muzzleloader hunting. Twelve bullets per box gives hunters enough supply for load development and a full hunting season. For muzzleloader hunters who want dependable accuracy paired with proven ELD-X terminal performance the Bore Driver delivers a purpose-built solution.
