You're in Prineville? My grandparents used to live there as well as my Uncle and Aunt. I have cousin's in that area still.
Don't suppose you know any Halsey folks.
Don't know any Halseys but it is a familiar name for Prineville area -- school teacher or principal?. Looks like you'll get a chamber cast tomorrow and find out just what you have, though the profiles are similar enough it'll take some close measuring to figure for sure I would suspect.
You can find 30/30 cartridges or brass everywhere, and last time I looked both Midway and Grafs had 30 Remington and 303 Savage brass. A few years ago both would have been tough to find: this is a great time to own and shoot old Savages!
