When using bushing dies, one has to go all the way with reloading, meaning one has to measure and record the wall thickness of your cartridges. The bushing sizes the neck from the outside, so that means the inside diameter will change with the wall thickness. Yes, different size bushings will accommodate this IF there is no variance within each lot of cases you are reloading. If the wall thickness varies from side to side, then it has to be turned down to create a uniform wall thickness. Once one starts to turn the material off the outside, Hornady suggest to only turn down to the point of only seeing about 2/3 to 3/4 of the neck being cut around the circumference. The reason is if you continue advancing the depth of cut to where it is a clean cut around the whole circumference, there is a good chance one has turned down the thickness too much to where the wall thickness is on the thin side or too thin.
When a case is initially made at the manufacturer, they start with the amount of material that is needed to make the final dimension. If the process is out of adjustment and creates an eccentric cartridge, being thicker on one side than the other, then the thin side ends up being thinner than it was meant to be.
Also if the walls are not uniform, any die will force the resultant inside diameter to be off center if the final sizing is from the outside.
There are some that will discard non-concentric shells for the eccentricity has a tendency to occur through the entire length so if the neck is fixed, then the inside diameter would not be concentric with the cavity inside the total cartridge case.
Information to think about as possibilities,
