Found a Drilling gunsmiths' special and picked it up. I have included photos of the proofs and stamps. From best I can tell upon a quick inspection the rifle barrel is a 9.3X72R. I want to take it on a grouse and moose hunt (if I can ever get drawn again). Anyone out there have a good BP load for a heavier cast. I would happily trade range for knockdown. 250 grain+?
