Check with out board sponsor and see what they can do for you.    I believe GBO Sponsor Ed Hart AKA Armorer77 said he makes moulds.  Look in the GBO Sponsor sticky at the top of the board for Ed's contact info.

That look like a good price for a jt-bullet brass mold. Can you pour zinc in a brass mold? If you get one of those molds let us know how it works.

I would think that would be OK as the melting points are much farther apart than zinc and aluminum.  However, I don't know whether there would be a problem of the zinc wetting the brass and not coming out.  You might have to smoke the cavity before using it.

Here is a discourse on casting in brass moulds.
