I recently acquired a beautiful Remington Hepburn from an uncles estate.Being an avid and excellent reloader,dear uncle had re-barreled the Hepburn.and I need help finding out what to load for this thing.The barrel is from the A&M rifle Co. Inc. and chambered in .17 A&M My delima, Just how much trouble is .17 A&M to load as I know it is probably an Ackley wildcat load.Any help with this would be appreciated.I have considered getting it re-barreled to a chamber that can be easily purchased and hand loaded but I have been told I will have to stay with a rimmed cartridge like the 30-30 due to the shell extractor design, so that being said ,Is there a cartridge ,rimmed,that would lend itself to long distance target and varmint shooting?The Hepburn has a bull barrel so plenty of meat to play with.
