The same steel is used in the 454C, 480R, 44mag, and 45colt barrels. That's not conjecture, that's a fact. Those revolvers aren't designed to be a safe factor over 14,000CUP, and that's why you see so many reloading manuals with Ruger Only load recommendations - proven safe in Ruger Revolvers.
I might not have moss on my back yet, but I've been rebuilding these things into Super Magnums through top end revolver smiths for a decade, and have burned about $30,000 getting conversions put together. This is the first time I've ever heard anyone say that the barrels need to be changed. If it were an issue, I reckon Hamilton Bowen would have mentioned it before now.
