I think it'd be worth that much just for the action alone. Buy it, get a barrel nut wrench and a make up an action vise. Then order a pre-chambered barrel from Shilen or Douglas in the short action cartridge of your choice that's threaded for the Savage action w/nut. You can rebarrel it yourself with just the above tools and a "GO" headspace gauge. Throw in a new trigger and voila, you've got a custom hunting rifle that will shoot darn near as well as a blueprinted Remington. If you want to go the extra step you can send it to Sharp Shooter Supply and have Fred time and true the action for $105 + shipping. There are also plenty of aftermarket stocks available for that era Savage Model 10 rifles, too for the full-custom treatment.
Or you could just take the good deal (and it is unless the rifle is beat to h*ll), and have a good shooting little .243 that you aren't afraid to put a few dings and scratches (read: character
) on.
