Western Cartridge Co. added a 2 3/4 inch 16-gauge to their Super-X offerings for 1938. From 1938 through 1942 they called this 16-gauge 2 3/4 inch Super-X shell "Magnum", even though it was still a 1 1/8 ounce payload. By Western Cartridge Co.'s March 7, 1946, catalogue the term "Magnum" was gone from this 2 3/4 inch 16-gauge Super-X shell. In Western's January 2,1947, catalogue, the 2 9/16 inch 16-gauge Super-X shell was gone from both the chilled shot and the Lubaloy offerings, and their only 2 9/16 inch shells being offered were Xpert. This may have been an oversight, as the 2 9/16 inch 16-gauge Super-X shell with chilled shot is back in Western Cartridge Co.'s April 8, 1948, catalogue and price list, and the 2 9/16 inch 16-gauge Super-X loads remained until their last appearance on Western Cartridge Co.'s January 2, 1962, catalogue and price lists, where it is "available until stocks depleted." By Western Cartridge Co.,s January 2, 1963, catalogue and price lists the new Mark 5 was introduced and all the 16-gauge Super-X offerings are 2 3/4 inch. By the January 2, 1964, Western Cartridge Co. catalogue and price list the 16-gauge 2 9/16 inch Xpert shell is gone as well.
