Abstract:
This report covers the second and third series of firing tests of 40mm barrel Type A Mod. 14 Serial No. 17 with short molybdenum liner Westinghouse No. BL 338. The liner was of lined worm construction consisting of 33 segments. The second segment which begins at about 12.125 in. from the breech face is made from one piece of molybdenum without the supporting steel ring. The molybdenum rings contained 0.2 cobalt forged discs having improvement in mechanical properties over previous molybdenum liners. The purpose of this test was to determine whether or not the subject barrel could withstand extended rapid-fire bursts using a hot propellant.
