I have the 500 with the 8 3/8" barrel and I love it. It is an absolute blast to shoot. I was surprised on how well the gun handles even when shooting the heavy loads. I shot pretty much every grain size made for this gun from 300 grain the the 500 grain Hornady rounds. I have never shot the 460 so I can't really compare the two. All I can say is the 500 is one of my favorites in my collection.
