A few things to note:
When dealing with Mauser actions, you need to be careful, as they are usually cheap up front, but more often then not, they can be more expensive to build up. You need to have the bolts turned down for scope use (Perhaps the mark X already is this way, some mausers are), you also need to drill and tap for scope mounts. Now, more specifically for the stocks: McMillan will only inlet a few of their stocks for mauser actions. But, you can always buy a "un-inletted" stock and have your gunsmith inlet it for the mauser. There are some stock designs that just wont work with the mauser, but I would suspect most of the McMillan stocks will do fine. I would recommend contacting McMillan and asking them directly. HS Does NO stocks for mauser. (though I know they do them for the CZ rifles, which are a mauser design, but the stocks are not offered to the public... kind of odd, maybe a call would reveal more details?). There are some other custom stock makers that just might do them for you. The problem is that there are so many flavors of mausers out there, that its hard to make a stock to inlet them all (and probably impossible....)
To be honest, since money IS an object, (and you didn't mention remington 700's) I would probably suggest a winchester 70 action, with a HS Precision stock with a custom barrel. This will probably be your cheapest route. (still gonna cost you a decent amount though)
Now, caliber choice. You must decide ahead of time because it effects you action choice. If you want a .300 Win Mag, you have to get a long action with a MAGNUM bolt face diameter. (.30-06, .270, 280, etc will NOT work). If you want .308, then you need the standard .30-06 bolt face diameter with a short action (.223, .17 Rem, etc will NOT work). So, be careful when you buy.
Hope this helped.
