Abstract: A charging block for a muzzle loading firearm includes an elongated block having a top face and a bottom face and side faces therebetween providing a vertical dimension. A plurality of shot-receiving apertures are disposed in the block and the apertures are angularly spaced apart on a generatrix of constant radius. A flexible punch pad is pivotally connected to the block at the generatrix. A punch block is secured to a second end of the punch pad and is alignable with the apertures by pivoting of the punch pad so that the punch block is positionable in the apertures. The punch block is of sufficient length to force shot from the apertures when the block is inserted fully therein.
