An adaptor (10) which allows a standard cartridge firing action to be used with a muzzle-loading firearm (100) is described. The adaptor includes a breech plug (12) and a nipple (16) and is configured to be inserted into the barrel (108) of the firearm adjacent the receiver (104). The breech end (16A) of the nipple (16) has a conical shape. In use, a standard ignition cartridge (150) with a casing (150A) and a head (150B) with a primer (154) mounted in the flash hole (152) in the head are loaded into the receiver of the firearm. Next, the ignition cartridge is moved into the breech end (108A) of the barrel such that: the casing extends into the center bore (14) of the breech plug and the breech end of the nipple extends into the end (152B of the flash hole in the head of the cartridge and is adjacent the primer. When the firearm is fired, the firing pin (114A) contacts the primer, which ignites the primer. The spark from the primer travels directly through the center bore of the nipple through the center openings of the propellant pellets (118) which ignites the propellant pellets which expels the projectile from the firearm.
