In Australia check out the importers/dealers selling the Chapuis and the Merkel for the least costly doubles in .470. Krieghoff is also worth a look.

Heym are reportedly of very good value and quality but this is reflected in a higher price. I understand Chris (new_guy) from Heym USA on here has sold to Aussie buyers as well.

Do the rounds and check them out.

Searcy is an import job so you have to do all that work yourself. And if it needs sending back for 'adjustment' you have to export and re-import it yourself as well. The others have importers/distributors.

There are other makers from Italy, Spain etc whom make an attractively priced product as well. Blaser is another maker if you want to consider their double rifle.

If you wished to consider a 9.3x74R the price of such a double is considerably less, as is other medium calibres.
