Psh...please... I love crazy stuff ;-)
That's a good question, honestly I'd work up this load like I would any other. In your case I'd just need the bullet you intend to shoot. If you don't have a preference, then the bullet weight's you'd like to shoot. I'll run a generic bullet, probably a Sierra Matchking, or if your looking for a hunting bullet then a Gameking. If it's a copper monolithic then I'll likely use a Barnes bullet.
There will be a few challenges with this project, but I would love to see what you end up with.
Thanks,
Jay Andrew
