I just wanted to say that I received the .480 today. I took it home, took off the cylinder and grips to give it a look-see. What I saw was that the gun had been cleaned well and properly maintained and lubricated. This revolver seems to be exactly as R-71 described. I've had shotguns show up with rust on the rib, so I really appreciate his thoroughness in maintenance.
He was also a gentleman throughout this transaction! If I were considering buying another gun from him, I wouldn't hesitate. He's been very helpful and straightforward throughout, and he did everything he said he would.
I haven't had the chance to shoot it yet, but if it does as well as the targets he provided (and I believe it will!), then I will be thoroughly satisfied.
Thank you R-71, it has been a pleasure completing this very smooth transaction.
