I have a ''Raging Lunatic'' and bought it used ... it is not actually that cheap a gun at all. I love it .. but do wonder when I poop off some hot 300 grain Hornady loads, just how well it'll stand up to the immense punishment. It is fine so far but I got a SRH also in .454 and being a fan of Ruger ruggedness and toughness .. feel a tad less bothered when shooting the biggest loads in that.
I think much depends on volume throughput ..... and I'd expect, round for round ... to see the Ruger staying tight longer than the RB. That said, yeah, the Taurus will take it ... it is still a tough gun.
