Jim.. If that pretty stock came off a 722, it will fit a short-actioned 700. The inletting for the barrel channel may (probably) have to be changed a bit, but the action itself will fit provided the new stock was not custom-bedded (re: glass bedded) to the original 722. If so, it can still be relieved some in tight areas and should drop into place. You probably should have it re-bedded. If the new stock comes with the floorplate assy. complete.. (re: spring, magazine box and follower), it too will work. If it does not come complete, these parts are available through various sources.. gunshows, gunsmiths, factory parts, Numrich Arms, etc..
Basically, I'd say go ahead and get it.. you will soon be enjoying your new love..
Guess I forgot to say that I have made this exact switch in reverse.. I put a beautiful custom blonde maple stock that came from a 700SA on a 722 in .222.. It worked out fine..
