I work part time at at a sporting goods store. I can tell you that shipping fees are extremely high and that many older folks are buying lots of 22lr. I can also tell you that there is an algorithm that kicks in to the stacking software of many sporting goods stores. When employees buy most of the 22lr the float or profit margin is lower at that store so they receive less resupply that stores that make a higher profit. Some stores are getting less 22 or than others.
