muley you should not be bumping the shoulders on new cases, just uniform the necks if necessary. On Nosler, Lapua or Norma the necks are typically good so they are ready to load without any prep. Once fired, the cases should not need the shoulder bumped back until the 3rd or 4th reload when they develop a crush fit. If you don't have one, I would highly recommend a Hornady Headspace tool

that fits on your caliper and hits the shoulder on the datum line
that will tell you how much the brass shoulder is moving forward on each firing. If you use Nosler brass then it will tell you if you have an older chamber by using it on new Nosler 280AI brass and some of your fired cases and comparing the 2 measurements.
If you are asking if the Nosler brass or your particular chamber will have an influence on this sequence, then no it will not. The Nosler brass will expand most of the way to the shoulder whether you have an older 280AI chamber or a newer SAAMI one.
In all likelihood you have a SAAMI chamber and should be able to use either the Nosler 280AI brass or any of the 280 Rem caliber brass.
