The Bore Driver delivers the ultimate in muzzleloader performance. At the heart of the system is a polymer base (not a sabot) that seals the bore to deliver maximum energy transfer and accuracy. Atop the base is an ELD-X or FTX bullet, featuring a rugged gilding metal jacket coupled with polymer tip technology and an InterLock ring that delivers maximum lethality.
