It’s started. 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.
