Obama to ban bullets by executive action, threatens top-selling AR-15 rifle
http://www.washingtonexaminer.com/article/2560750
As promised, President Obama is using executive actions to impose gun control on the nation, targeting the top-selling rifle in the country, the AR-15 style semi-automatic, with a ban on one of the most-used AR bullets by sportsmen and target shooters.
The Bureau of Alcohol, Tobacco, Firearms and Explosives this month revealed that it is putting the ban on 5.56mm ammo on a fast track, immediately driving up the price of the bullets and prompting retailers, including the huge outdoors company Cabela’s, to urge sportsmen to urge Congress to stop the president.
Yes, it’s the 40gr, green-tipped 5.56/.223 M855 round that he’s opening the back door with; then they’re going after every other round, for every firearm that they can get rammed thru, under the radar. Store I PT work for was sold out weeks ago, and none now in the pipeline. BP spiking... Glad I stocked-up on that one and selected others, years ago.
Is there a list of calibers?
