IN STOCK NOW! Federal XM556SBCT3 5.56 NATO 62 gr Tactical Bonded Softpoint Cartridges

100 rounds of Federal XM556SBCT3 62 grain Tactical Bonded Softpoint cartridges in caliber 5.56 NATO. Packaged 20 Rounds per carton. Made in USA by Lake City Ammunition Plant.

We also offer 200 rounds and a factory-sealed 1,000 round case of this cartridge.

This is the same ammunition as the FBI contract XM556FBIT3
. It was given a different SKU# for a non-FBI contract, which would be done for any agency other than the FBI. This is the real deal, and is not labeled as a "second" by the manufacturer (XM556FBIT3M) because it failed the FBI's accuracy requirements. Nor is it the "reclassified" ammunition
(RXM556T3). It comes fresh to us from the manufacturer through an intermediary. It is the 5.56mm version of the Federal Trophy Bonded Bear Claw (TBBC) Bonded .223 JSP (LE223T3).

The round is known for its reliability, and ability to defeat tough barriers with minimal deviation while maintaining accuracy and terminal performance.

"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." DocGKR

Many rifles chambered in 5.56 NATO are not realizing their full potential when shooting 223 Rem ammo. To get all the performance 5.56 NATO can deliver, you need a 5.56 NATO load. 5.56 NATO chambered rifles were designed to take advantage of the higher pressure of the 5.56 NATO cartridge — higher pressure translates to increased velocity, higher energy and harder-hitting performance. CAUTION: Firing 5.56 NATO ammunition in 223 Remington chambers will produce a dramatic rise in pressure which increases stress on the weapon, risking wear, permanent damage and/or injury. NOTE: NOT for use in 223 REM chambered guns!

"The new Federal 5.56 mm 62 gr TBBC bonded JSP (XM556FBIT3), as well as the older .223 55 & 62 gr TBBC bonded JSP's ( LE223T1 & LE223T3), the new 5.56 mm Win 64 gr bonded JSP (Q3313/RA556B), and the new 5.56 mm BH 50 gr TSX are the BEST general purpose loads available for LE use today." Dr. Gary Roberts

(Regarding Duty ammunition for Colt M4A1 with 11.5" barrel) "Your best bet is a 5.56 mm (not .223) loading of a barrier blind projectile. The 5.56 mm Federal 62 gr Trophy Bonded Bear Claw (TBBC) bonded JSP (XM556FBIT3) and 5.56 mm Winchester 64 gr solid base bonded JSP (Q3313/RA556B) developed for the FBI are optimal solutions, the Black Hills 5.56 mm 50 gr TSX loading and Hornady 5.56 mm 55 gr GMX are also acceptable options. Speer Gold Dot 62/64 gr 5.56 mm loadings would also work well." Dr. Gary Roberts

"The original law enforcement designation (government contract number) was XM556FBIT3 for the FBI. Then the number XM556SBCT3 appeared that was either the new/current contract number or the civilian number for the same round. More recently, the number RXM556T3 appeared which seems to be contract rejects/seconds for the XM556SBCT3 number. My understanding is RXM556T3 represents production lots that didn't meet the contract specs, but otherwise fit for use."

"The barrier blind, FBI issued, ATK/Federal 62gr bonded Tactical load on top has completely upset within the first 2" of gel penetration, demonstrating good tissue crush and stretch:" Dr. Gary Roberts
