I asked a wildcatter to make a 400 whelen for me from 30/06 brass.That was his answer

also,Daryl,you said that I can make a 416 Taylor just necking up a 338 winchester case,but what about the shoulder position?I have the wildcat 416/338 winchester magnum,made simply by necking up a 338 case but it is similar but not identical to the 416 Taylor.
