I think the 480 Ruger is a very practical bigger bore cartridge. I like 475 Linebaugh, but think the 480 will do whatever I need with a bit less fuss.
I have only seen one of the Ruger Bisley in 480, and I liked it. Had intentions of buying it, IF it would have been there 2 weeks longer.
I do have a new version of Super Redhawk 480 at the gunsmith's. The barrel is being cut to 5".
Shot my new Ruger Bisley Blackhawk this past weekend. These are the 5 shot, 6½" barrel stainless versions.

Recoil was quite tolerable, and accuracy excellent. It probably will kick harder with the big 355 or 370gr WFN bullets, but I think it's going to work very nicely.
