연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

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.

1. A muzzleloader firing system comprising 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 system further comprising a muzzleloader propellant cartridge without a projectile therein, the propellant cartridge sized for being received by the breech end of the muzzleloader, the cartridge comprising: a cartridge cup portion comprising a polymer and having a tubular wall portion and a closed end of the tubular wall with a converging portion unitary with the tubular wall portion, the cup portion defining an interior;a head portion connecting with the tubular wall portion of the cup portion, the head portion having a primer centrally engaged in the head portion; andpropellant filling the interior and extending to the closed end;the system further comprising a projectile sized to the barrel and further sized to not pass through the constriction portion. 2. The system of claim 1 wherein the cup portion closed end has a conical portion and a portion extending perpendicular to an axis of the cartridge. 3. The system of claim 1, wherein the cartridge cup portion closed end is rounded. 4. The system of claim 2 wherein an angle measured in an axial plane from the outside surface of the tubular portion to the outside surface of the conical portion is from 115 degrees to 155 degrees. 5. The system of claim 1, wherein the cartridge cup portion is injection molded. 6. A muzzleloader firing system comprising a 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, a hermetically sealed propellant cartridge having propellant therein and not having a projectile therein and having a closed and unitary polymer cup sized for conforming to the surface of the constriction portion facing the breech end, the system further comprising a projectile for loading in the muzzle end, the projectile being received forward of the constriction portion wherein the projectile comprises a bullet body and a cup portion engaged on the body. 7. A muzzleloader firing system comprising a 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, a hermetically sealed propellant cartridge having propellant therein and not having a projectile therein and having a closed and unitary polymer cup sized for conforming to the surface of the constriction portion facing the breech end, the system further comprising a projectile for loading in the muzzle end, the projectile being received forward of the constriction portion further comprising a ramrod having two engagement portions, one for the projectile bullet body and one for the cup portion. 8. A muzzleloader firing system comprising a 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, a hermetically sealed propellant cartridge having propellant therein and not having a projectile therein and having a closed and unitary polymer cup sized for conforming to the surface of the constriction portion facing the breech end, the system further comprising a projectile for loading in the muzzle end, the projectile being received forward of the constriction portion wherein the propellant cartridge has a head portion that conforms and is secured to the cup portion, the head portion having an end flange and a recess for a primer. 9. A muzzleloader firing system comprising a 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, a hermetically sealed propellant cartridge having propellant therein and not having a projectile therein and having a closed and unitary polymer cup sized for conforming to the surface of the constriction portion facing the breech end, the system further comprising a projectile for loading in the muzzle end, the projectile being received forward of the constriction portion wherein the surface of the constriction portion facing the muzzle end is perpendicular to an axis of the barrel of the muzzleloader. 10.
