470 is the biggest Chapuis makes and the only chambering you want among those offered. Google Chapuis Armes and choose English. They're good utility grade guns. The Cabela's gun is $10,999 and has a wood upgrade from AAA to AAAA wood and upgraded enhanced engraving. Most dealers sell the base guns in 470 for retail, $11,775-11,999. The Cabelas Chapuis is a decent deal, if they still have one and you must have new and must have it now. Heirloom Armes has the best prices on new Chapuis but you have to order it. I'd say look for one used but there are too few about.
