I don't have a long action Savage to measure but the opening on the action on a Savage short action is only 1/16" shorter than my long action rifles made by Remington, Winchester, Ruger, or Tikka. My .308 Remington is about 3/4" shorter than my Savage .308. That is not really a bad thing but for some reason Savage does use actions where the openings and bolt throw are a good bit longer than others.
