Ok, no fotos but I got the reamer hardened and sharpened, then drilled the die to size and reamed it out. Worked pretty shnazzy, but I learned one important thing that I'd wondered about: tool flex. It made sense to not relieve the trailing edge so it would drag and keep the cutting edge pressed against the work (like a following rest in a way), and I tried not to touch it when cutting the relief....but got carried away and ground off a few thousandths anyway. Oops. So the reamer went all the way in and barely cut at all. What I had to do was choke up on the reamer with the tailstock chuck, leave the quill lock fully loose to give a little lateral wiggle, and apply pressure to the side of the chuck with a bar (no hands! Stuff that can break, dig in, and suddenly spin like an MT chuck is no-touchy territory) to flex the reamer to the side to get it to bite. Fortunately I managed not to bell the hole doing that and it turned out just fine.
I ran out of time to make an "I" ejector, so no finished bullets yet, but I sized a few with vise, hammer and punch and they turned out almost exactly as intended. When sizing 21 BHN heat treated bullets, the nose band is about half a thousandth large at .2191", the taper is spot-on, and the base is a little small at .2256". I might hone out the base a little more on the lathe with a rod and sandpaper since I got a little trailing-edge leading with bullets smaller than .2265".
The die also works very well to uniform and slightly re-shape the 75-grain, powder-coated silhouette bullets that I use for subsonic loads. That will ensure that the noses will chamber reliably in my ARs. The powder coating introduces enough thickness variable to jam occasionally and the odd elliptical bullet can get stuck in the throat. The air-cooled ww bullets sized out at .2185" on the end of the nose, just perfect for my rifles.
