Check theother firearms forums and you'll find a LOT of folks having not so positive things to say about thier Taurus firearms. Do you really think the dealer, the person selling the gun, would offer up negative comments about what they sell? If you're really needing the .480 chambering, look for a Ruger SBH.
Also, remember that this sin't a widely popular chambering so ammo might not always be readily available. If you're to reload that's a whole different story.
