The Giraud, also like the Gracey, does chamfer at the same time so not total equivalent. My scheme on this is using a second station in the progressive the run a Squirrel Daddy expander down into the necks to size them on the way in instead of the way out, and part of my theory is that it will break the edge on the way in. Still not totally proven but it seemed to work on the first Qty500 300BO I did that way.
