On the subject of strange/crappy shotgun loads, has anyone heard about the 'chain-shot' recently re-introduced according to the March edition of Australian Shooter. It was originally used against air ships and the sails of ships to tear the material. To quote the magazine

'From an American catalouge shown to me recently, it seems that 12-gauge chain shot is now commercially available. With the current scarsity of both Zeppelins and wooden line-of-battle ships, one could be excused for wondering why'

If anyone can think of a reason why this would exist would you please tell me. Also has anyone used them...
