I read in an African hunting novel one time that "Owning a double rifle is God's way of saying you have too much money."
Yes, doubles are expensive. Most things that take that much time and attention are. Go to a GOOD gun store and look at their selection. Stores like Sportman's, and Cabelas often have several on hand. The wood to metal fit is usually top notch. The metal is usually engraved or inlayed with gold and silver. And my favorite part is the quality of the wood. Many are exhibition grades of walnut
The majority of guns today are $10,000+, with some ranging into the hundreds of thousands of $$$!
