I have a set of 8 Lyman 457125 500 Gr RN that have been converted by Magma for use on their Bullet Master casting machine. These moulds are lightly used, came from the estate of a gent that used them to feed his Trapdoor's and 1883 Gatling. These moulds are from the mid to late 70's. They are in very good condition, lite surface rust on the tops of the sprue plates, cavities are very nice and should cast very nicely. Asking $400 OBO for the set. Will consider breaking the set if there is enough interest in doing so. More pics are available to those interested. PM here or text me 225-324-4501 Payment via Postal money order , PayPal or Credit Card plus fees.
