If I had a mold for a good 300 gr. WFN I would probably shoot them just because. Think I will wait til I stop one of the 429421 bullets though before I buy one.
If you can stomach Lee moulds, the Lee 44 310 is pretty slick. And comes in a 6-cavity mould for less than $50 bucks. One good casting session, and you've paid for it several times.
