There have been changes and attempts at changes with the Obama administration.
For one, the republicans managed to attach a rider to the bill overhauling consumer credit that Obama signed into law. The rider makes it where federal parks, forests, etc now have the same rules regarding firearms as the state which those parks are within. For example, here in Georgia I am legal to carry in a state park. Because of the rider, I am now legal to carry on federal lands as well, whereas before that was not the case.
Eric Holder attempted to have all brass not used by the military sent to be shredded and then sold to China as scrap metal. This brass is a huge source of casings for both reloaders as well as ammunition manufacturers. When six senators sent letters to the Defense Department wanting more information, the order to destroy the excess brass was shelved.
