Mississippi. There is a lot of work to converting a Mauser action to sporting configuration. Just some of the tasks include grinding down the raised portion at the rear ring that supported the clip loading feature. Then the bolt handle had to be refigured either by cutting it off and welding on a new one, or by heating and reforging it to a new shape so that the handle will clear a scope. The action face has to be squared, and the action polished out for smoothness of operation. It has to be polished and blued. Drilled and tapped. Decent work such as this is highly labor intensive, and costs money. Excellent work is even more expensive.
The last mauser I had done up ran a hair over $2,800. Was it worth it. To me it was. Excellent work? No just decent.For excellence, go to David Miller in Tucson. Rifles based on Mausers start at $15,000 and go up from there, and you have a minimum of a 5 year wait. It it worth it? I'm not sure. At 15 grand, you have a basic plain sporter, albeit, made with the most meticulous care.
When I plan to build another custom sporter using a Mauser action, I cruise the gun shows looking for a J.C. Higgins model 50 rifle. A genuine F.N. Mauser action, stock and barrel by High Standard. Stock is rather plain walnut and somewhat blocky, but some judicious work with files and sandpaper will turn it into a rather nice feeling and quick handling sporter with classic lines. They are usually fairly accurate. The last one I bought did 3/8 inch with the first handload I put in it. Granted it was a match grade load with military match brass, hand weighed charges and a 190 gr. Hornady match hollow point.
If you want to go farther in customization, a lot of the work of fixing up the action will not be needed and money in labor charges saved there.
JMHO.
