I think there might be a misunderstanding.

Just guessing here...OP is a new poster, perhaps a newbie to the world of Savage was told that appropriate bolt length depended on the stock, I took his response to be a question about what were the different stocks that required different action screws so that he could get the right length action screw.

He could have been asking what stocks MacMaster Carr sells, but I think not.

vczar1: Please try to clarify your question. It will also help you get a better answer.

Generally wood stocks need slightly longer action screws than factory plastic/composite ones. Best bet IMHO is to get a longer action screw and cut/file/grind it down until it is the right length for you.
