I don't have access to that over 1" in diameter, but my boss has broken drills around 2" in diameter and he's pretty much giving me the tapers. My reamer materials don't really cost me much.
That also looks like a simple reamer design, I was going to cut flutes in it and everything with an indexer.
However that should all be moot, as I'm designing two-part dies; they will look like a bullet mold, but the "second half" is the shoulder and neck area, that can be swapped out with the subsequent sizing. I can do all that with boring bars, since I don't have to work with an inside bore 5" long that goes to 0.587"; a half-inch diameter boring bar 5" long wouldn't cut much. With the two-part dies, I can cut the case body from the head, down to the neck, with a carbide boring bar from the wide end in. For the shoulders and neck, I can cut them the same way with a smaller boring bar, from the shoulder to the neck. I can prep the material first without too much trouble with pre-holes and dowel index holes, I've done that before, that part should be peachy.
That's the plan after the first fire, even if I'll be making them as close to chamber size as possible.

So that means I have more chances of seeing a gold-dipped CWO-5 orbiting Jupiter than ever sniffing a waft of that powder, carried along the breeze from the US to here. Because ITAR would block somehow.

Also, I am jelly of your quickload, can you post the data or something?
