Licensed manufacturers, importers, dealers, and collectors are required to create and maintain disposition records on armor-piercing ammunition. These records are used primarily for law enforcement purposes and may be used to trace ammunition collected as evidence during a criminal investigation or court presentation. The records are required by 18 U.S.C. 922 and are necessary to support ATF's mission to enforce the Gun Control Act, particularly tracing ammunition used in crimes. Information Collection (IC) OMB #1140-0066 is being revised to change the title of the ICR to reflect that the record-keeping requirement applies to licensed manufacturers, importers, dealers, and collectors.
