A superior system. When you have a detachable box magazine system as good as the one found in the X-Bolt then it pays to have an extra along when you want nothing to risk your hunt's success. The X-Bolt uses a detachable rotary magazine constructed from a durable lightweight polymer.  The magazine feeds cartridges directly in line with the bolt, instead of offset as with traditional leaf-spring magazines, for a straight path right into the chamber.
