Zachary,
Hello to you, it's been awhile, if I' reading you correctly the stock that I have for my old Tikka Whitetail Hunter in 270 should fit on a new Tikka T-3. I would assume the new T-3 receiver is the same length as the old long action receiver, the only difference being that the new action as a spacer inside if you wanted a caliber that was suppose to go into a short action. Is that correct assumption to make on both counts.
