With PowerBelt Bullets, you are shooting a muzzleloading bullet designed specifically for muzzleloading rifles, as opposed to a pistol bullet adapted to fit a muzzleloader. Unlike sabots, PowerBelt Bullets are full caliber sized, easy to load, and do not require cleaning after every shot. The PowerBelt base provides consistent gas pressures for almost identical bullet velocity every time, and protects the tail of the bullet from flame cutting.
