Welcome to ShootersForum, Chevelle699.
If you look up www.overbore.com
, you should find data for that cartridge.
( OK, that's not really a website, but it would be perfect for such a 'cat! )
I have done some diligent searching in my reference books and I can't find anything on that particular combination, although Quickload does list it. I'm sure it will take relatively large doses of slow-burning powder, but hopefully someone else on the forum will know where you can get some actual data. If not, Uncle Nick might help you get started.
