ABSTRACT:
In an explosive charge setting gun used for driving fastening elements into a hard target material, caseless charges are positioned in a magazine duct and are separated by spacers. A movable element in the gun picks up a caseless charge from the magazine and moves it into position to be fired. The movable member includes an ejector which displaces the spacer following the charge, from the magazine. The movable element can be a slidable barrel or a separate slide member. The ejector can be formed as recesses or cams on the movable element. The spacers are shaped so that they are not picked up by the movable element when a charge is moved into the firing position.
