A week before the ATF was going to stop receiving public comments about its proposal to ban so-called 'armor-piercing' ammo the agency shut down the whole process, announced they were going back to the drawing board and, at some later date not specified, would revisit the whole issue again. The ATF received more than 80,000 emails and if you think some of them came from the International Bible Holiness Movement or another of the frontline anti-gun violence groups, think again.
And if you don't believe the NRA isn't celebrating, you're wrong on that one, too. They immediately posted victory statements from Wayne and Chris, sent news releases out to ever-welcoming Fox which featured their next President, Rand Paul, speaking out against the ATF, and of course went out of their way to label the ATF decision as a "defeat" of their arch-enemy and all-time best gun salesman, a.k.a. Barack.
Any time the gunnies can push back the U.S. Government on a gun issue, they'll celebrate their victory as yet another step towards enshrining the 2nd Amendment as the unquestioned law of the land. By the same token, the gun-sense folks will bemoan yet another defeat at the hands of a seemingly all-powerful NRA and try to figure out how to keep this embarrassing loss from happening again.
