Former member from years ago, I now sell Guns for a living. I had a customer from Minnesota who had a firearm his now deceased father in law gifted to him. We are having some trouble figuring out what exactly it is. It is a Dan Wesson frame rebarreled to a cartridge called the 458 ultracolt. On the other side of the barrel it is marked ultra arms. He is wondering value and where he would find brass dies and load info for it. Any info would sure help. Thanks much.
