1. A weapon for firing cased telescoped (CT) ammunition rounds, the weapon comprising:
a barrel;
a chamber member that defines a chamber configured to hold a CT round for firing from the weapon;
a carrier body; and
linkage that moves the chamber member (i) from a firing position in which the chamber member is aligned with the barrel for firing the CT round to an ejection/loading position in which the chamber member is not aligned with the barrel for ejecting a spent CT round and receiving a next CT round in response to the carrier body moving away from the barrel, and (ii) from the ejection/loading position to the firing position in response to the carrier body moving toward the barrel, wherein the linkage includes:
a linkage feature that pushes the chamber member from the firing position into the ejection/loading position in response to movement of the carrier body moving in a recoil direction away from the barrel and pushes 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 a carrier body travel axis, and
a chamber carrier having grooves that are 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.
