I'll post this and pass on a conversation I had with a Cabela's store manager last spring. Lead long gun metal is now imported. The dollar is strong relative to most export nation's currencies. Ammunition manufacturers have opted to put most of the expenditures into rounds for calibers that will generate better return. As a portion of the .22 caliber production has dried-up, hoarders have made a point of jumping on any shipment, buying it up and either reselling it on-line at extreme mark-up, or sitting on their supply. He shared with his own analysis of a shipment his store received. When the .22 rounds were placed on the shelf, several folks showed-up and purchased all of the existing inventory, literally overnight. He said he tracked a couple of on-line sites and monitored the location of the folks posting new .22 round quantities for sale at, what he called extreme mark-ups. He said he saw his shipment for sale on-line, that's right, nearly the entire shipment up for sale on-line.
