Muzzleloader power cell with primer
Muzzleloader systems including a pre-packaged propellant charge with a primer and receptacle. The muzzleloader system may include a propellant containment vessel separate from the primer and the projectile and that doesn't contact with the projectile until assembly. The muzzleloader may be rear loading, with a constriction portion forward of the breech chamber. The propellant containment vessel may include a body portion having a forward opening, with a propellant charge disposed therein and a cap portion that is crimp rolled within the mouth of the vessel to seal the forward opening. The closed end of the propellant containment vessel may define a primer receptacle configured to receive the primer. The receptacle may define a depth that is less than the primer height so that, when inserted into the receptacle, the primer extends rearwardly beyond the containment vessel. The muzzleloader system may be configured to fire only specifically configured propellant containment vessels.
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.
2. The propellant system of claim 1 , wherein the propellant is hermetically sealed in the propellant containment vessel.
3. The propellant system of claim 1 , wherein the primer receptacle is configured to removably receive the primer.
4. The propellant system of claim 1 wherein the propellant containment vessel comprises a rearward cup portion that defines a cavity and a mouth at a forward end.
5. The propellant system of claim 4 , wherein the propellant containment vessel further comprises an interior wall and a ledge portion that is rearward of the mouth and projects radially inward from the interior wall.
6. The propellant system of claim 5 , wherein the propellant containment vessel further comprises a cap that is secured in the mouth of the rearward cup portion and configured to seal the cavity.
7. The propellant system of claim 6 , wherein the cap comprises an over-powder disk comprising a forward face and a rearward face, the rearward face being seated on the ledge portion, the mouth further comprising a roll-crimp that engages the forward face of the over-powder disk.
8. The propellant system of claim 1 , wherein the containment vessel is closed by way of a polymer webbing.
9. A muzzleloader power cell for use with a primer comprising:
a propellant containment vessel comprising:
a forward end;
a rearward cup portion that comprises a cavity, and the rearward cup portion comprising a closed rearward end; and
a primer receptacle comprised in the closed rearward end defining a primer recess configured to receive the primer, wherein the primer recess has an axial length shorter than an axial length of the primer, and wherein the primer is selected based on a caliber associated with the power cell; and
a propellant disposed in the cavity,
wherein the propellant containment vessel does not comprise the primer and a projectile, wherein the propellant containment vessel is configured not to contact the projectile, and wherein the propellant containment is configured to removably receive the primer.
10. The power cell of claim 9 , further comprising:
a mouth at the forward end; and
a cap that is secured in the mouth of the rearward cup portion to seal the cavity,
wherein the propellant containment vessel further comprises an interior wall and a ledge portion that is rearward of the mouth that projects radially inward from the interior wall of the propellant containment vessel; and
the cap comprises an over-powder disk comprising a forward face and a rearward face, the rearward face being seated on the ledge portion, the mouth further comprising a roll-crimp that engages the forward face of the over-powder disk.
11. The power cell of claim 10 , wherein the ledge portion comprises a continuous annular ledge portion.
12. The power cell of claim 11 , wherein the ledge portion comprises a distal face of a shoulder.
13. The power cell of claim 9 , wherein the closed rearward end comprises a rearward face, and the primer receptacle comprises an annular projection that extends axially from rearward face.
14. The power cell of claim 9 , further comprising:
a mouth at the forward end; and
a cap that is secured in the mouth of the rearward cup portion to seal the cavity, wherein the cap comprises a forward cup portion comprising a frangible diaphragm portion configured to rupture upon ignition of the propellant.
15. The power cell of claim 9 , further comprising:
a mouth at the forward end; and
a cap that is secured in the mouth of the rearward cup portion to seal the cavity, wherein the cap comprises a forward cup portion that hermetically seals the propellant containment vessel and is configured to be propelled forwardly upon ignition of the propellant.
16. The power cell of claim 9 , wherein the rearward cup portion comprises a transparent or translucent material configured so that the propellant is visible therethrough.
17. The power cell of claim 9 , wherein the containment vessel is closed by way of a polymer webbing.
18. A method of manufacturing a propellant system for a muzzleloader rifle, comprising:
filling a propellant containment vessel with propellant, wherein the propellant containment vessel is configured for rearward loading into a breech chamber of the muzzleloader rifle;
the propellant containment vessel comprising a rearward end and a flange comprising a rearward-facing flange face at the rearward end, the rearward-facing flange face comprising a primer receptacle,
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; and
sealing the propellant containment vessel.
19. The method of claim 18 , wherein the primer receptacle is configured to removably receive the primer.
