Abstract

Muzzleloader systems include a pre-packaged propellant charge and primer for providing efficient loading and unloading of the muzzleloader. The muzzleloader accepts in the breech end the propellant containment vessel that abuts against a constriction portion with a reduced diameter portion. The propellant containment vessel having an end portion with a tapered surface that conforms to the constriction portion surface. A projectile is inserted in the muzzle end and seats against the constriction portion. The propellant containment vessel may be received in a removable breech plug. The constriction portion may be part of the breech plug or a separate component secured in the barrel by way of the breech plug. The containment vessel further comprises a primer mechanism that may be integrated into the proximal end of the containment vessel.

First claim

What is claimed is:

1. A breech-loading muzzleloader propellant cartridge for loading in a breech-loading muzzleloader having a barrel with a breech chamber open rearwardly, a constriction portion at a forward end of the breech chamber, and a projectile bore portion with a bore forward of the constriction portion, the breech-loading muzzleloader propellant cartridge comprising:
a unitary polymer tubular portion defining an axial cavity, comprising
a distal end comprising an inward crimp,
a proximal closed end, comprising
a flange portion comprising a diameter greater than a diameter of the unitary tubular portion, and
a recess for receiving a primer,

propellant inside the axial cavity, and
the distal end further comprising a polymer disk, the inward crimp being configured to engage the polymer disk,
wherein the breech-loading muzzleloader propellant cartridge does not comprise a projectile.

2. The breech-loading muzzleloader propellant cartridge of claim 1 , wherein the breech-loading muzzleloader propellant cartridge does not comprise structure to retain a projectile.

3. A breech-loading muzzleloader propellant cartridge for loading in a breech-loading muzzleloader having a barrel with a breech chamber open rearwardly, a constriction portion at a forward end of the breech chamber, and a projectile bore portion with a bore forward of the constriction portion, the breech-loading muzzleloader propellant cartridge comprising:
a unitary tubular portion defining an axial cavity, comprising
a distal end,
a proximal closed end, comprising
a flange portion comprising a diameter greater than a diameter of the unitary tubular portion, and
a recess for receiving a primer,

propellant inside the axial cavity, and
the distal end further comprising a disk and a crimp, the crimp sealing the propellant and the disk within the unitary tubular portion,
wherein the breech-loading muzzleloader propellant cartridge does not comprise a projectile.

4. The breech-loading muzzleloader propellant cartridge of claim 3 , wherein the breech-loading muzzleloader propellant cartridge does not comprise structure to retain a projectile.

5. The breech-loading muzzleloader propellant cartridge of claim 3 , wherein the unitary tubular portion and disk consist of a polymer.

6. The breech-loading muzzleloader propellant cartridge of claim 3 , wherein the distal end further comprises a containment mechanism.

7. The breech-loading muzzleloader propellant cartridge of claim 3 , wherein the distal end further comprises a weakening structure.

8. The breech-loading muzzleloader propellant cartridge of claim 3 , wherein the unitary tubular portion and disk are unitary.

9. A breech-loading muzzleloader propellant cartridge for loading in a breech-loading muzzleloader having a barrel with a breech chamber open rearwardly, a constriction portion at a forward end of the breech chamber, and a projectile bore portion with a bore forward of the constriction portion, the breech-loading muzzleloader propellant cartridge comprising:
a tubular portion defining an axial cavity, comprising
a distal closed end,
a proximal closed end, comprising
a flange portion comprising a diameter greater than a diameter of the unitary tubular portion, and
a recess for receiving a primer, and

propellant inside the axial cavity,
wherein the breech-loading muzzleloader propellant cartridge does not comprise a projectile.

10. The breech-loading muzzleloader propellant cartridge of claim 9 , wherein the tubular portion is unitary.

11. The breech-loading muzzleloader propellant cartridge of claim 9 , the distal closed end further comprising a disk.

12. The breech-loading muzzleloader propellant cartridge of claim 11 , wherein the tubular portion and disk are unitary.

13. The breech-loading muzzleloader propellant cartridge of claim 9 , wherein the distal end further comprises a weakening structure.

14. The breech-loading muzzleloader propellant cartridge of claim 9 , wherein the distal end further comprises a containment mechanism.

15. The breech-loading muzzleloader propellant cartridge of claim 9 , wherein the distal end further comprises a crimp.

16. The breech-loading muzzleloader propellant cartridge of claim 9 , wherein the breech-loading muzzleloader propellant cartridge does not comprise structure to retain a projectile.

17. The breech-loading muzzleloader propellant cartridge of claim 9 , wherein the unitary tubular portion consists of a polymer.
