Savage has made 2 different short actions. The earlier 4.27" staggerfeed and the newer 4.41" centerfeed. This is what the 10 stands for and is the short action. The long action is called the 110 and measures 5.062". The inch numbers are the space between the action screws.
What type of stock are you looking for? I have a few of the choates with the aluminum bedding block and they are nice , but heavier. ce61
