In my rifles and single shot pistol I have found FL sizing with a slight shoulder bump to be more accurate. I think but can't prove that if the case has the ability to center itself on the bolt face and the bullet in the throat you'll have better accuracy. I've tried neck sizing with bushings and without and could not achieve better accuracy. I shot some old LC Match M118 79 rounds at 200 yards three days ago and got a 1/2" group at 200 yards with 5 rounds. Everyone knows that LC Match brass is crap for concentricity in the neck and body, and the headspace is .005" smaller/shorter than the 1980 Rem 700 BDL Varmint I shot it through! Just some food for thought.
