right but the key words are depending on what caliber.
My Rem 700 6BR needs it as well as my 6PPC. These fellows tend to run on the higher end of the pressure spectrum. They must be bumped every time or the bolt close is, NO.
I set all my dies so they bump about 2 thou back. If you ever order a set of Harrells dies that is how they are made, to bump the shoulder a few thou back.
With my limited experience in different calibers I have found that the more taper in the case from base to neck determines how much brass flow and whether or not the shoulder needs moving back. When I had my 22-250 it needed constant bumping and I am finding that my new 243 Win needs it as well. Tapered cases.
My opinion and no one is going to change it.
I can tell you that my Sako TRG in 30-06 does not stretch at all. I have yet to bump the shoulders back on it. I just use a RCBS neck die and that is it.
