I am saving now for a #1 in .405. I think I can have some fun with it shooting B.P and cast bullets, Shoot lighter bullets for deer size game and load it as hot as I can for moose and elk in the timber. And should I ever get another chance to do Africa I would haul it along just to see what it can do with the heavy bullets.

I think any of the rounds you spoke of would be a great choice. Good luck!
