Picked up a Master Caster and 24 sets of molds came with the machine, only one was a Magma. The Modern-Bond mold that was included is the first of these I have owned, maybe ever seen. B-358-742 double cavity is a 358 diameter cast 160 grain round nose from early 38 S&W days. The handles were over designed compared to Ideal/Lyman and will probably be a dream to use. The mold is not something I will need to cast, unless this bullet would work well in a lever 357 mag gun. Will these handles fit Ideal/lyman molds? The arms that go into the mold slots for the M-B and Lyman are both 0.312". The mold handle bolts appear to go completely thru the mold and are the sprue pivot and the sprue stop. It appears a long bolt from the end of the mold is used to lock the the two handle screws.
If these handles will not fit other molds, will probably leave together. Any one swapped these over?
