I think a few of your responses thought that you were asking about a .460 Rowland rather than the Model 460 Taurus which is a Tracker chambered in .45 Long Colt.
I picked up my M460 Tracker today. I'll let you know how it shoots after I get it to the range but for now I can tell you that I own several Taurus revolvers and they are all quality firearms. They also provide you with a lifetime warranty.
As far as shooting heavy loads goes, I don't see any reason why the M460 Tracker would have any problem with them. This very same model is also chambered in the .357 magnum and .41 magnum. If you are loading your .45 Long Colts to pressures greater than these then I would suggest getting a .454 Casull.
As far as the Hogden manual I wouldn't consider the firearms mentioned to be the only ones capable of handling those loads. People have been hotloading .45 colts for ages. It is also worth mentioning that this is a fairly new revolver so I doubt Hogden even tested one before printing their manual. But most importantly I can tell you that Taurus had produced a Raging Bull model in .45 Long Colt which Hogden didn't mention in their manual either, it would be rediculous to assume that since it is not mentioned in the Hogden manual that it therefore cannot handle these loads.
Anyway you had not mentioned reloading or shooting any heavy loads in your original post so if you just wanted an opinion then I personally prefer the Taurus. They have excellent quality and I personally feel that they look nicer but that is just my opinion :grin:
And if you are going to reload then just remember when working any loads up to start with a safe load and build your way up slowly from there. I don't see any reason why this gun wouldn't handle the loads mentioned but I could always be corrected
