Check out the book 'Cartridges of the World'. It's in there, with load data. I thnk you'll find it's not a whole lot different from a 25-06, 270, 280 Remington, and you can get factory dies and brass for them. I'm pretty sure that in a rifle, the ctge approximates the over-rated 264 Win Mag (it's very inefficient)I'm not trying to talk you out of though cuz it's one caliber that always facinated me too. One cannot have too many wildcats! I can't wait to hear out you like it.
