Yank, considering the value of your prize, I would be purchasing about thirty brass hulls from Rocky Mountain Cartridge Company. They are ten bucks each, but you won't have to worry about a lot of the hassle of industrial shells. RMC hulls take the 209 primers and will last forever. I recomment smokeless loads to simplify the cleaning of the gun and the cleaning of the hulls. I have exactly thirty RMC hulls for my eights and don't expect they will ever wear out. These hulls are wonderful products and you will enjoy looking at them even if you don't shoot them. Bill Murphy
