Greetings Joel,
As your die setting is providing good results right now I would just keep using it and see if any problems develop. I suspect that they won't. I have my FL die for my 6.5 adjusted and locked so the sized cases just chamber. My die just barely sizes the necks so is much in line with what you are achieving with your FL bushing die. It is possible that the fired cases you are using have been fired with light loads which makes the cases a little shorter to the shoulder as the case is driven forward by the primer and not expanded by the pressure. For me I would just work with what you now have and turn the die down a smidgen more if chambering becomes tight. If the case lengthens on sizing the shoulder moves with it. Put the comparator in a drawer for now.
Regards Grandpamac.
