Fast and easy to load, the Bore DriverA(R) FTXA(R) 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 the FTXA(R) bullet, featuring a rugged gilding metal jacket coupled with patented FlexTipA(R) technology and an InterLockA(R) ring that deliver maximum lethality. FlexTipA(R) initiates expansion even at low velocities enabling enhanced muzzleloader terminal performance.
