Eventually you will need to bump the shoulder back so why not full length resize with minimum shoulder bump and still headspace of the case shoulder.
The make of case and its thickness just above the belt may cause you problems. The case may bulge above the belt and the die may not size the case enough just above the belt.
If the case does bulge it can cause the case to bind in the chamber and hard bolt lift. Larry Willis makes a belted magnum collet resizing die the will size the case just above the belt.
