Since you're relatively new at this let me suggest the simplistic solution...are you sure you even need to bump the shoulder at all? I have one rifle I need to bump every 2-3 loadings, and another that I'm on the 7th reload and have not had to do more than neck size yet.
The rule I follow with bolt guns is not to bump the shoulder unless you have to -- be kind to your brass. My full-length dies are rarely used. Get a neck sizing die and it will be simpler for you.
If you have to bump, start small and test the brass in the gun. If you go all the way back to SAAMI this will really be over-working the brass for a lot of guns. If the shells are being reloaded for a specific chamber there is no reason to do this.
