Yes it is useful, look at what all competitive shooters are doing. The best is to float the action and stock, using a barrel block, secondly, and much more doable, is to bed the whole reciever (except on some like savages where you float the tang). I just did this 45minutes ago. Either tomorrow I'll post about my new rifle, or a new post filled with explict words asking how to unglue an action from a stock
So far it's been a fun and satisfying activity.
