    Wanted a hand operated casting machine that would use MP 4 cavity Brass molds

    I would like to find a Manual Bullet casting machine simular to a Magma Master Caster that would allow for 4 cavity molds. I already own over 20 MP 4 cavity brass molds, I hate the idea of going back and buying 2 cavity molds for such a machine.
    I would prefer to buy an existing machine but would consider the buld plans also. Since MP Molds are made in Europe I would consider a machine made in Europe.

    The closest thing to what you're describing used to be made by Polykilips, in Italy, and is now out of production. But it used a 6-bullet mold. Although I suppose you could retrofit one to use 4-bullet molds.

    The molds are different. It would require major modifications to work with a standard 4c mold
    Don't like being hammered by the Cast Boolits Staff, then don't be a nail.
    The rules are simple to follow.

    I too have a Master Caster. Have an assortment of moulds. Looking at the two cavity moulds; they are notched or machined between the top pour holes so the lead flows into both cavities. To fit up a 4-cavity mould the top fill holes would have to be cut with a ball cutter so the lead will flow and fill all four cavities. I think it could be done.

    Have you tried a mold guide on your furnace? I have quite a few 4 cavity MP hp molds, and yes they are heavy suckers.
