Popis:	Bore quality of experimental 40 mm seamless gun tubes made from ingots cast in a standard 20 x23 ingot mold and in the same mold with carbon inserts in the bottom are compared. Previous work indicated that high rejections of the bottom tubes was not primarily due to non-metallic inclusions but rather to the inherent weakness of structure of this part of the ingot, assumed to be associated with the cone of solidification formed b solidification from the mold walls and bottom of the mold. The object of the carbon insert was to restrict this cone in the portion of the ingot which is normally cropped off. The use of the carbon insert was successful in greatly restricting the cone of solidification, and brought about redistribution of non-metallic in the bottom half of the ingot. The top half of the ingot was unchanged in this respect.
