I keep threatening to buy a Ruger .416 #1, but the barrels are too heavy IMO, the "D" contour. Tempted at some point to get a .375 (the "C" contour) and rebore it to .416
Another way to lighten the barrel on the Ruger 416 Rigby RSM is to rebore it and rechamber it to 450 Rigby.
Just had one done and getting ready to develop some loads. Reloading data is pretty slim, though!
