Actually, if you fire form a belted case and only neck size, you no longer have a belted case in reality because the case, head spaces on the shoulder and the same rules that apply to non belted cases now apply to the belted case.
The belt becomes non functional if sized this way. so you can full length size the belted case and it will function the way it was designed, or you can neck size only and it negates the function of the belt and acts just like a non belted case because when fired, the case moves back to take up the few thousandths headspace and the front of the belt no longer comes in contact with the chamber belt recess and now has zero head space because the shoulder is the new contact point.
When I head space belted cartridges that I intend to size the necks only
I wont go over .002 thousandths for head space. For dangerous game I like .002 to .003 and full length size for trouble free chambering.
Just my way
