Was the 22-7.62 for the Salvo test made as a duplex and triplex loading or just one or the other? If they were made in both types how do you tell the difference?



The .22/7.62 was at least made in duplex version with an extended neck. There is a sectioned view of one in Journal issue 342 on page 6. I don’t know about triplex or, if they exist, how one could tell the difference upon external examination.
