ATF fails to respond to FOIA request
So, Judicial Watch is suing them:
The ATF is reportedly reconsidering its February 2015 proposal to revise the 2014 Regulation Guide regarding the reclassification of certain ammunition. In March 2015, more than 200 members of Congress wrote to former ATF director Todd Jones expressing their serious concern that the proposal might violate the Second Amendment by restricting ammunition that had been primarily used for sporting purposes. The letter asserts the ATFs move does not comport with the letter or spirit of the law and will interfere with Second Amendment rights by disrupting the market for ammunition that law abiding Americans use for sporting and other legitimate purposes.
Judicial Watch filed the lawsuit after the agency failed to respond to a March 9, 2015, FOIA request seeking information on the ammo ban effort
