My road to the .400 Whelen and .400 Whelen-B of 2013 included this from 2000 AD:
That would make a nice rebore to .458 WinMag. I wonder if JES can do a 1:10" twist .458 rebore ? I would shorten the barrel and thread it for suppressor if it could be re-bored with 1:10" twist.
That’s a cool Ruger!
And very neat about the bullet sizing. Never done it. I should though.
