...But if you have factual information on the contrary, please post your source.
My source si myself, and factual information I can give you because my personal experiences give me this right: I've seen three - not one, but three -S&W revolvers in .460 Magnum blowing up in front of my eyes, and one of this, a 12" PC Hunter model, at no more of 10 inches from my nose, and no more of two minutes after I shot it myself! I can assure you my friend that in Italy is not so common to see someone with a revolver like the .460 Magnum: my country is really backward in this way!
But, you are right about one thing, I've explained myself badly, I admit: I
didn't want to say that
all S&W X-frames are not enough strong or safe,
but only ones chambering .460, because, I believe, of his high pressures and velocities. On the other hand, if I don't make a mistake, S&W X-frame was designed around .500 S&W cartridge, that work at very low pressures than .460. Correct?
Unfortunately, in Italy .500 S&W revolvers are not imported (neither S&W nor BFR), so about S&W fifty caliber I can't judge... "better for us", you'll think partners!
However I don't want argue for these bulls**t
