Grab any of the Savages, long or short, and do what you want. $250-500 for the gun (sell what you don't use), $325 for bbl, $100 for wrenches and parts from NSS, $100-1000 for stock/chassis, $100 for trigger. Scope, base and rings and gonna cost ya if you plan to go long, but that's the way of the world these days.

If you drop $15 for a membership on Savageshooters you get access to their classifieds. Between that and cruising the other forums (Snipershide, Snipercentral, Calguns, Long Range Hunting, Accurateshooter and AR15 - those two have horrible search functions, but huge communities), you can find some good deals and good guys to help you with your build.

If you go the Savage route, you give up a little in parts selection, but you can do all the same stuff with a Remington and a CBI Remage (Savington), either way, call Jim Briggs at NSS (on the telephone as he's a small shop).
