    Nice pattern and foundry work.

    So, Jim.....does it work as you intended?
    Does it use a standard, over-the-counter sizing die?
    Will it accept rifle length, as well as pistol length dies?
    Is there any commercially available counterpart in that design?

    If the answers are in your favor, you just started a sideline business!
    Or get your patent, and license it to one of the big boys.

    Is there any commercially available counterpart in that design? Not really, whats out there sizes from bottom up not top down,
    bottom up makes collecting the sized bullets difficult, this will drop them in a pan below it

    Many years ago I worked with a bench rest shooter to build bullet swaging dies. He wanted to drop a lead slug in the die, then apply pressure to form the slug to the die cavity, there was a vent to allow excess lead to escape. The aim was to get super accurately sized and weight bullets. The dies were made with 7/8-14 threads so they fit his reloading press. Unfortunately he pass away unexpectedly so the project never was finished.
    What is that squeaking noise?

    It takes a LOT of force to swage bullets, his reloading press likely wouldn't have survived,
    and this little guy certainly isn't up to that task.

    Really nice work. Showcases what you can do with aluminum casting!

    Poured another set today, able to fit everything in one flask



    Made an attempt at adding name and location, worked well




    And, may have made a mistake, I got orders for 5 of these today :0

    Punished by success. May we all be that lucky. Looks great! Have you thought of adding a core where the die and plunger go through the main body of the casting? It may actually improve the as-cast strength of the final product, helping align the grain pattern better.

    I have not ventured into cores yet.
    This would be an easy one though, except for reworking the pattern a little

    This might be an excellent situation for a matchplate. Add the needed cores, and half the finish work is done. (Well, maybe a third.)

    And now that you've gotten eight advance orders, maybe you should re-think investing in a patent. Being as you've shown it around, you're open to design "theft" by someone who could get the patent, and file charges against you for infringement.
