There are only two explanations possible for the decision to deliberately make policed military brass un-recyclable (1) to make ammunition more expensive and less available to both the military and the public, or (2) utter stammering dumb-assedness.

I would vote for (all of the above) since it is the clearly stated purpose of the administration to reduce U.S. military capability overall; it has also been the clearly stated policy of the Democratic Party for the last 4 decades to deny U.S. citizens the right to own firearms. Finally, those people are certifiable.
