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."
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.
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."

(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
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

"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."
