A dealer here in Calif sent me email today telling me he has an Army Navy 450/400 3 1/4.. I plan on calling him in the morning. Being very new to the double rifle world I have'nt a clue on value or what to look for, let alone cartridge performance and availability.. I need help fast and am relying on fellow NitroXer's to bail me out... BTW the dealer a specializes in hi end double rifles and shotguns.. He stands 100% behind all his sales.Thanks Guy's450
