The Model 70 Classic and later Winchesters M70s will make great 404 Jeffery rifles, I have one made from a .300 RUM re-barreled.
No doubt they would make a great .460 G&A or .450 G&A Short Magnum.
Either one will do fine.
After trying
.460 WBY X 2
.450 Dakota X 1
.458/.338 Lapua Magnum X 2
.450 Barnes Supreme X 1
.458 Lott X 2
.458/.416 Ruger X 1
.458 B&M X 1
.458 Winchester Magnum X A BAKER'S DOZEN ...
I choose the .458 WinMag, happily ever after.
