I almost always fl size my hunting rounds,but only bump shoulders enough to chamber nicely,although not really sure if you have to worry as much with a belted case but it can't hurt.

IIRC belted cases were developed as a way to reduce the rim dia on straight or slightly tapered large bore cartridges. The belt is not required for a case that has a shoulder large enough to control forward movement and headspace. Modern magnum designs do not have belts.
IMHO bottleneck belted cases will likely have better accuracy and MUCH better service life if the belt is ignored and NOT used for headspace control. The proper minimum shoulder bump will allow the case to headspace on the shoulder.
FL sizing a belted case to SAAMI minimum can be justified, to aid reliable chambering of dirty ammo or in a dirty chamber, when dealing with dangerous game.

Good luck
Or use the proper over-height Redding Competition shell holder from their 5 pc set. They eliminate the need to adjust FL dies or to even tighten the die locking ring.
Some suggest allowing the die to float slightly to improve body concentricity, by using a loose die nut or an O-ring under the nut, (but I have not tested this and have my doubts), I use the Comp Shell Holder set because it is fast, easy, repeatable, and consistent even when using different presses.
Unfortunately, they are not inexpensive.

Good Luck, YMMV.
