I have recently acquired a half dozen assorted 14.5mm sub-calibre rounds and am struggling to identify them accurately. I have read Will Reuter’s excellent article in IAA Journal 470 and, although these two cartridges are pictured, the article does not fully explain the two very different projectiles. Can anybody help with identifying them please? I know nothing about these so any help would be appreciated!
This second cartridge has a removeable nose section which I suspect contains an impact fuse of some sort.
