How are bullet molds made? For the lube grooves and whatnot to be features of the mold, a simple drilled or killed hole wouldn’t work. Seems like an EDM might work, but more likely a custom ground sidecutting endmill would do the trick. That sounds expensive and would make molds somewhat expensive. Last option would be for the plates to be cast around an item to make the shape. All seem fairly expensive for manufacturing and I can’t figure out how molds are as cheap as they are.
Does Anybody actually know how a set of molds are made?
