With inlines the Co2 system is not really needed as you can pull the breech plug and push the load out. Although I see no reason why it would not work. In a traditional rifle on the other hand, there is no breech plug to pull (unless you have a Firestorm, PA Hunter, RMC, or one of the custom ones). So here the Co2 discharger would work real good.
you gave me idea,i wonder if threads could be put inside a powerbelt hollow point bullet so you could pull it out at end of day.
