Basically bumping back means adjusting the die so that it compresses the case more?

Do I have that correct please?
Yes. When resizing, the brass was compressed and pushed the shoulder up. All chambers are slightly different. It helps to have a comparator to measure the headspace, but you could probably bump it by trial an error if you adjust the die in small amounts and test in your chamber.
