Sounds like an interesting conversion, the only drawback ( a major one to me ) is the case is a Bottle-Neck cartridge and as such it isn't as "easy" to reload. You will have to lube each case, I don't think anyone makes a carbide die for it.
And while not an answer about the 400 Corbon, you should mention the 460 Rowland to him. Check the " 460 Rowland" post. It is far "easier/better"... ( subject to your opinion...)
