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. Copper-plated PowerBelts have a thin copper plating which greatly reduces lead fouling and bore friction for higher velocities while still allowing for optimal bullet expansion within the rifling grooves. This 50 caliber bullet is 245 GR with a hollow point.
