.433" or .434" if I powder coat

I have a 44mag Rossi 92 rifle that needs .434" bullets (slugs at .433"). I will be powder coating and am undecided if I should I order a .433" or .434" mold.

edit: never mind I guess, just realized the molds offered by NOE are either 432 or 434, nothing listed for 433.
