I got a .416 rigby Encore barrel I will sell you. Not too many rhino stampedes here in Oregon but I had to have it. You could shoot with cast bullets. I have some brass as well it is the ported 28" pro-hunter stainless model.
With full house smokeless loads it will cross your eyes.
also another really good choice would be the 45-70 barrel
very straight forward loading proposition. Mine is not for sale however they are available often. The .35 whelen is a little touchy but once you get it dialed in it's a killer
