Product Number: AC1597AT: PowerBelt Bullets are designed specifically for muzzleloading rifles, offering an alternative to pistol bullets adapted for muzzleloading. What sets PowerBelt Bullets apart is their full caliber size that simplifies the loading process and eliminates the need for cleaning after each shot.The unique PowerBelt base contributes to consistent gas pressures, allowing for virtually identical bullet velocity for each shot. It also protects the bullet\'s tail end against flame cutting. All PowerBelts have a thin copper layer that mitigates lead fouling and bore friction, which ultimately leads to enhanced velocities. This design still provides optimal room for bullet expansion within the rifling grooves.The AeroTip bullets outperform hollow point bullets in terms of ballistic coefficient at longer distances and have shown to be slightly more precise. The aerodynamic design of the AeroTip reduces wind resistance post firing, and provides greater penetration on game before expansion happens. The AeroTip version is preferable for hunting large game or for long-range hunting.This product includes a 54-caliber bullet, weighing 348 GR, complete with an AeroTip.
