I read a well written article not long ago that broke down the numbers on the ammo purchases by agency. It showed how, despite what seemed like large orders, these are large agencies and they will go through large amounts of ammunition every year just in training and qualification testing for their agents....."So see, nothing going on....nothing to be alarmed about."
The problem I have with that route of thinking, a problem which they have never answered when it was brought forth, is that these large purchases of .223 and .40S&W were secondary purchases done on top of their standard yearly contract demands.....and not even the Feds are wasteful enough with the money to be punching paper with hollow-points. That's what they bulk order FMJ for every year. As my grandpa always said, "They're armed for bear" and it would be nice to get an honest answer why.
