Abstract
In an explosive charge driven setting gun for inserting fastening elements into a hard receiving material, caseless charges are positioned in an opening in a holding member prior to being inserted into the firing chamber. A feed member in the gun displaces the charges from the holding member opening into the firing chamber and a plunger located on the opposite side of the firing chamber from the feed member is movable through the chamber for clearing an unfired charge or any residue of a fired charge. The holding member can be a magazine or a separate slide movably mounted in the gun housing. Preferably, the opening in the holding member, the feed member, the plunger and the firing chamber all have the same cross sectional shape viewed transversely of the firing direction of the gun.
