Thanks, 400NitroExpress,
You have cleared my mind muchly. I guess if shoe lumps are just as strong as monoblocks I might as well look for the smooth barrel. The 450/.400 sure is a sweet little round that shouldn't loosen my fillings. My only fear was being like Hemingway's wife Pauline, when she pricked her lion with the 6.5 Mannlicher, leaving EH and the PH to finish him off with the bigger stuff.
