Ejecting.
Ejecting is throwing the
empty case from the rifle. As the bolt
moves to the rear, withdrawing the case
from the chamber, the round is held in
place by the chamber walls. When the
mouth of the empty case clears the cham-
ber, it is ejected up and to the right by
the expanding ejector spring and ejector.
Cocking. Cocking occurs when the ham-

mer is forced into the proper position for
firing the next round. This happens as
the bolt continues to the rear. The rear
end of the bolt forces the hammer back
and rides over it. The hammer is caught
by the sear if the trigger is still held to
the rear, but it is caught by the trigger
lugs if trigger pressure has been released
(fig. 31).
