Like stated, you need a model 10 stock for a short action or the 110 for a long. There are two styles. The new one has a measurement of 4.4 for center feed short action in the detachable magazine model. I do believe the blind box model is also a 4.4" and center feed also. The older models have a stagard feed and the short action measures 4.27". Just measure as close to center to center of the action screws and that will tell you. As for stocks, you can go McMillian, Manners, and H-S Precision. There is also the XLR and McRee for really nice tactical aluminum chassis. But the best bang for the buck is the Bell & Carlson Medalist A2.
However... if you want a really good stock with pricing options that give you a Savage specific built product, then Stockade Stocks is the way to go hands down. Kevin Rayhill is top notch when it comes to Savage built rifles and his quality of products. My cousin uses his Prairie Dog/Tactical stock. It is a very nice stock. He just ordered another for his wife's F-Class gun he is building her. He offers three models. The money saver (need to skim coat with body filler, sand, prime and paint), Pre-primed, and finished stock which is about a $150 dollar difference from the money saver. He has many different options that can customize the stock to fit you.
Now don't get me wrong, the other companies can do that for you too, but I really admire Kevin for his customer service. If you call him to order, be prepared to talk for a while. He is a talker.
When I get around to building another rifle, I am going to use his Groundhog stock model or the benchrest model.
