I've never been one to knock an exotic rifle or calibre if it suits the owner. At least you will have something different from anyone else. It certainly would be a usuable rifle, mild enough and still kill well.

Bullets would be easy to get. Cases I believe are the same as the 9.3x64mm (?) and those might be a little harder. I would price some cases before I got too committed especially if you are like me and plan to buy 200 plus for any rifle.
