"Bad Ammo"
According to Obama administration the 223 is bad ammo, but considering its never been used to kill a police officer, why all the sudden need to take it away from us. Literally a police officer has never been killed with this type of round.
For starters the 223 is a widely used round used for sporting and hunting enthusiasts. Its the most common form of ammo in civilian and military sectors and the cheapest round to fire.
The fact that this round needs to be ban now because Obama could not ban the Ar-15 is unconstitutional.
