Company's like Federal, Winchester,Remington, make large amounts of certain calibers, then stash the dies for a few years. Once the demand gets great enough, they'll make more. I'm sure with metal price's going up, the major company's are going watch, real careful, how much excess brass there is. Their certainly not going to make a run of a million cases, if they don't think they can't get sell it to the distributors in short order. gypsyman
