Anyone familiar with the cartridge for the Wilson conversion? Apparently some of the converted rifles were used during the US Civil War. I recently received an email from a South African who is researching for a book on Thomas Wilson, and is looking for information on the cartridge.
As is usual for me when I get an inquiry about a cartridge (no one seems to ask about the easy ones) - I hadn’t a clue. I checked my usual resources and stumbled across a listing in Vol VII, No 3 of Butweiller’s catalog for a Wilson/Terry .577 cartridge packet. Could this be the cartridge he is looking for?
