Claim 12:
13. A method of operating a weapon for firing cased telescoped (CT) ammunition rounds, the method comprising:
moving a chamber member, which defines a chamber configured to hold a CT round for firing from the weapon, from a firing position in which the chamber member is aligned with a barrel of the weapon to an ejection/loading position of the weapon in which the chamber member is not aligned with the barrel, at least in part by a linkage feature pushing the chamber member from the firing position into the ejection/loading position in response to movement of a carrier body moving in a recoil direction away from the barrel;
after the chamber reaches the ejection/loading position, moving the chamber member from the ejection/loading position to the firing position in response to a non-rotating carrier body moving toward the barrel along a carrier body travel axis during firing of the weapon, ejecting a spent CT round, and receiving a next CT round in response to the non-rotating carrier body of the weapon moving away from the barrel, at least in part by the linkage feature pushing the chamber member from the ejection/loading position into the firing position in response to movement of the carrier body moving in a counter recoil direction toward the barrel, the recoil direction being opposite the counter recoil direction along the carrier body travel axis; and
wherein grooves of a chamber carrier are maintained in constant mechanical communication with the linkage feature, the chamber member being retained by the chamber carrier and moving along a vertical axis that is perpendicular to the carrier body travel axis.
