A good chamfer also helps on the inside of the case mouth.
I Go one step further, After I size them, I trim them to length and turn the outside of the necks
just enough to clean them up and then weight sort them to look for culls.
This lets me start with "Good" brass and makes working up loads easier, saving time and components. It also assures good fire forming to my chamber and for 4 or 5 loads I don't have to
do anything to my brass
Just the way I do it.
