I recently acquired a Remington Hepburn from the estate of an uncle ,old unk had been reloading most of his life and was really into wildcat loads.The Hepburn at some point had been re-barreled with a Bull barrel from the A&M rifle Co .Inc. in a " .17 A&M " I am trying to find all the info on this round as possible ! If any one can help it would be appreciated
