If you could use some .432"d lead wire ( rod actually), I have some @$1.70/lb + postage, shipped via USPS Flat rate box not to exceed 65 pounds. 2 years ago I was selling this wire ( I make a lot of different diameters) for $.35/lb, but the market has gone nuts. I also have a used/excellent condition 3 barrel Corbin adjustable .430 bench mound mold @ $120 + postage. The mold is a much better option for this size diameter IF you have access to 99.99% pure lead if you intend to swage the cores in smaller dies.
