Yeah, should be no reason to list or declare anything unless you are exporting or something. Other than the question about if you are shipping anything hazardous or liquid or such, no other questions should be asked.
I agree but there are so many uninformed postal workers it's always a crap shoot what you will be confronted with.
My local Post Mistress frequently ask me if I'm shipping a firearm and request a copy of the FFL. I always satisfy her request although I'm not required to. She's been very helpful and I don't want to ruin a good relationship.
