Loading fast and easy is a core design goal of the Bore Driver system letting hunters get a muzzleloader ready to fire without a fiddly time consuming loading process in the field. The 280 grain weight is matched to .45 caliber muzzleloader barrels to deliver flat trajectories and retained energy at distances beyond what traditional round ball or conical loads can manage. That combination of speed of loading and extended range accuracy is what sets the Bore Driver apart from older style muzzleloader projectiles. Each box contains 12 bullets organized into four 3 pack speed loaders a packaging choice that speeds up reloading in the field during an active hunt.

The emphasis on maximum lethality paired with extended range performance makes this a purpose built option for hunters chasing deer elk or other big game with a muzzleloader. For hunters who want the range and accuracy of modern bullet design without giving up the muzzleloader season the Thompson Center Bore Driver ELD-X is a strong choice.
