Patent attributes
Projectile carriers are provided. In one aspect, a projectile carrier has a storage area with a breech opening and a bolt opening aligned with the breech opening along a first axis, a plurality of projectile drivers positioned in the storage area are biased to move in a first direction within the storage area along a path that passes between the breech opening and the bore opening. A stop is positioned to stop movement of the projectile drivers in the first direction when one of the projectile drivers is positioned substantially aligned at the first axis. The projectile drivers have a block that prevents a projectile from exiting the bolt opening. The projectile drivers are sized and can be moved in a second direction to allow a bolt to drive a projectile along the first axis through the breech opening.
