I have asked the same questions! I finally got a straight answer. As my wife, daughter and I were in the factory Blaser store in SA during the world skeet finals. I ask what makes these 3 shotguns so expensive. They were the same receiver and barrels. One was 5300, 9300, 15000. He looked at me and said the wood! I said what!!!! He told me that the wood was from a 300 year old tree in some forest in Europe that I had never heard of. It was pretty but not 10000 dollars pretty! My daughter's shotgun coach told me one time that for some people the look of the stock was everything!
