The facer cutter just cuts a 90º flat crown, no recess, the crown cutter cuts a recessed target crown also, it's made for 22 cal barrel, but works up to .30 cal. I've used it on the 38-55s with a jury rigged pilot, but it just makes a slight chamfer at the crown, the recess cutter isn't much wider than the bore, much the same as you'd get using a carriage bolt and grit in a drill.
