Huck: Are you sure the inserts were chambered for .22 WRM? I am not aware of the factory ever doing that. They were always in .22 LR. It might have been done by an owner down the line. Anyhoo.......... if the revolver was in good condition the asking price is more than fair, but your 80% condition report doesn't support that asking price. The Jet ammo is available but not real common anymore. You would more than likely have to order it from one of the internet companies. The Jet is a literal pain in the left ear to shoot. Most people shoot them with ear plugs and muffs both. Jets are love/hate handgun. As usual, this is IMHO ...... Big Cholla
