Mike,
From your description of the rifle, you have a Composite Stalker. Does the bolt have what appears to be horizontal flutes (original A-bolt) or does it have a non-rotating shroud covering the bolt(A-bolt II)?
If it's an A-bolt II, you done just fine on the price. They are no longer made and most folks are asking quite a bit of coin for them now or at least in my opinion.
I've owned more A-bolts than I have any other rifle and will tell you, that unless you've got a lemon, that rifle will do far better than 2" @ 100yds. I've never had a complaint with the accuracy of any A-bolt I've owned.
The cheapest and one of the best improvements that you can make to that rifle is purchasing a lighter set of trigger springs from Timney, they're available at MidwayUSA as well; this will help improve accuracy.
Congrats on your purchase. I love the Composite Stalkers and it's chambered in a great caliber. Enjoy your rifle.
