Ammunition can be found through Ammoseek for $129 per box. Just because the Model 8 became famous for being used in the Bonnie and Clyde massacre, doesn't mean it is worth the price. It will still depend on condition as to the collector price. I have had the opportunity to shoot one of these, along with the Model 81. The recoiling barrel gives it a unique feel, but it is still very uncomfortable. I, also, saw the same rifle during a complete strip and clean. Rust between the barrel housing and barrel. It looked like it had not been cleaned since it was new. All said, it is a very good caliber to hunt with, but you better be a good shot.
