Exactly. I've seen increased accuracy many times with a little barrel shortening--and no, it wasn't due to the new crown, because the crown had already been "refreshed" in a search for better accuracy with the longer barrel.
As an experiment, I once shortened the barrel of a .300 Winchester Magnum to 22". Not only did it shoot better, but with published data it still got 3000 fps with 180-grain bullets. So it didn't exactly turn into a .30-06 or .308....
