I had to buy two .431 sizer dies and send them to be modified to .432 and .433 to cover my sizing needs. I was told the largest commercial size available was .431. Lathesmith's Custom Dies on the Cast Boolet Forum offers this service. He can be found in the Vendor/Sponsor section. Good luck.

Still on the search
I might end up ordering whatever I can get and honing it up to size and making a punch to match - but I'd prefer to not have to spend bench time on this. My bench time is best spent working on guns for the clients.
