Did you clean your brass before you took the pics? If there was soot back onto the shoulder, it supports the light pressure concept.
Someone asked me if I cleaned them and I said no. That wasn't an accurate statement.
I didn't tumble them, but I did use some 0000 steel wool to wipe the necks. There was soot on the neck and shoulder, but not that much if I remember correctly.
