Running through the Giraud after "sizing" new brass gains uniformity in length and chamfer.
The first pass through a die only trues up the brass, no shoulder bump of course.
Neck diameter gets the bushing massage.
After all that a mandrel makes sure holes are round and consistent.
I do fire new brass at least once on mild loads. May take another at full power to fully form it. I guess it depends on chamber size vs brass from the start.
