One way to approach it is to only bump shoulders when chambering starts to get tight. Another way is to bump every time in order to increase consistency in case dimensions from firing to firing.

A Forstner neck size shoulder bump bushing die only touches the shoulder and the neck most dies people are bumping the shoulder with are also sizing parts of the rest of the case some.
