1. A propellant system for a muzzleloader rifle, comprising:
a propellant containment vessel with propellant sealed therein, the propellant containment vessel being configured for rearward loading into a breech chamber comprising a breech block face of the muzzleloader rifle and comprising:
a rearward end;
a flange comprising a rearward-facing flange face at the rearward end; and
a primer receptacle in the rearward-facing flange face, the primer receptacle comprising a depth that is less than an overall height of a primer configured to be used with the propellant containment vessel, such that when inserted into the primer receptacle the primer extends rearwardly beyond the rearward-facing flange face of the propellant containment vessel,
wherein the depth is configured such that the primer is received in a recess in the breech block face configured to receive a portion of the primer that extends rearwardly beyond the rearward-facing flange face of the propellant containment vessel.
