What high-dollar ammo do they use?

The FBI has completed their testing process and awarded a 5.56 mm ammunition contract for up to $97 million dollars. This award is now public information and appears unique in several ways. Besides being perhaps the largest ammunition contract in FBI history, it is also the first time the FBI has mandated a true 5.56 mm pressure loading, rather than the typical anemic .223 pressure loadings that have generally been marketed to LE agencies. The 5.56 mm load offers approximately an extra 200 fps--helping performance out of short barrel weapons and enhancing function when rifles are dirty or in dusty conditions. The new FBI contract also required that the ammunition be packaged on stripper clips to aid in more rapid loading of magazines. Finally, it is the first multi-award carbine ammo contract for the FBI--both Federal Cartridge and Winchester were judged to offer ammunition which met the contract criteria. Numerous other Federal LE agencies are authorized to purchase off this contract.

The 5.56 mm Federal 62 gr Trophy Bonded Bear Claw (TBBC) bonded JSP load is XM556FBIT3.

The 5.56 mm Winchester 64 gr solid base bonded JSP is Q3313 on stripper clips/RA556B in 20 rd boxes.

Both of these loads are the best barrier blind 5.56 mm loads ever produced for LE use; they offer outstanding terminal performance, even after first defeating intermediate barriers like vehicle windshields.
