The only reason I own a 300 WSM is because of one of those deals you can't pass up. I found a SS 70 with a Burris scope that I was able to get for $400 also several years ago. I didn't do quite as good as you since someone had ruined the tupperware stock. I picked up one from CDNN for $50 that I used for a while.
It's been a gradual project, but it is now in an Edge stock with lighter bottom metal. With the Leupold 3-9X40 on it weight is 7.5 lbs.
I still haven't figured out why I need a 300 WSM, but I like the rifle.
