Abstract
A loading tube for use in a perforating gun is disclosed which eliminates the necessity for utilization of plastic jackets to restrain shaped charges. The loading tube comprises a first tubular member and an engagement structure in the first tubular member in which the primer ends of the shaped charges may be installed.

In each of the disclosed embodiments, a detonating cord connects the primer ends of the shaped charges which are installed in the loading tube.
