After a federal judge rejected a class action settlement with Remington Arms Co. due to an “appalling” claims rate, lawyers in the case scrambled to reach out to more gun owners. They put together a targeted ad campaign on Facebook and radio that was estimated to reach 74 percent of class members.

More than a year later, their efforts paid off: The total number of claims jumped from 2,327 to 22,000. And on Tuesday, U.S. District Judge Ortrie Smith in Kansas City, Missouri, gave his final approval of the deal.
