My pick would be the M70, I have three a , 7x57 FW, .264 and 270 WSM. in extreme.
I think finding one New might be a problem, I see a couple of used ones up for sale on EE,
One thing about Model 70, is they have good resale value, and normally the used rack will have a dozen, rem, savages, brownings etc, and one lonely M70.
