He was sure he wasn’t doing it right and is opting the neck sizing die

It sounds like he was trying to neck size with full length die which can work if preserving brass and adding a little accuracy is what he's trying to achieve.basically he will need a Hornady head space gauge/comparator or sinclair comparator with the inserts for measuring datum line on shoulder so that way he can measure that he's bumped shoulder back .002-.003 for bolt guns more needed for gas guns.
Just start with die backed out 1/2 turn out or more then keep adjusting down until it's bumped shoulder back
