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
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
The T2 bullet profile is specifically designed to enhance
function and feeding in M16/M4 variant guns and the cartridge’s
propellant technology is custom designed to enhance weapon operation,
and delivers phenomenal temperature stability. The 75 gr BTHP T2
bullet is designed to deliver
rapid incapacitation upon
impact. The cases are manufactured to mil-spec hardness and feature
staked and sealed primers and sealed case mouths. The T2 bullet is
not available from Hornady as a reloading component.
The closest military round is the Navy Mk262 Mod0. Both perform well
short barrel rifles (14.5 inches and under) and deliver
match accuracy for use by snipers with consistent
devastating tissue damage. These are not projectiles for
"For short barrel rifles (14.5 inches and under) and snipers there is
another round to fit the bill of large wound cavities and match grade
accuracy. This is the 75 grain Boat Tail Hollow Point Match T2 TAP.
Similar to the Navy Mk262 Mod0 round this round delivers match
accuracy for use by snipers with consistent devastating tissue
damage. This is not a projectile for barrier penetration."

"I spoke with a good friend with multiple combat tours in
both Iraq and Afghanistan. His experiences as both a Special Forces
sniper team leader and assaulter offered a unique perspective on ammo
performance. As a sniper, MK 262 was his preferred round (when he was
not using 7.62x51mm NATO), and he said simply, “It’s the
best, most accurate round the Army has ever issued.” When
carrying the shorter SBR, he ranked Hornady’s 75-grain TAP as
the most lethal..."
75gr T2 TAP is an OTM bullet. The main advantage of using a
heavy OTM is precision. A secondary advantage is fragmentation. It is
not designed for barrier penetration or expansion. 75gr TAP's main
wounding mechanism is violent fragmentation with an extremely early
neck length when impacting soft tissue. It will begin to fragment
within the first 2", penetrating well into the FBI's recommended
12"-18" ideal penetration depth.
"The top performers in the fragmenting, heavy OTM type category are
Hornady’s 5.56mm 75 grain TAP T2 , the Nosler 77 grain
Custom Competition and the new
Ammunition load utilizing the Sierra 77 grain Tipped MatchKing

"On unobstructed shots, the 75 gr OTM and Mk318 Mod0 will generally
offer similar tissue disruption, however the base of the SOST round
will likely exit the suspect while the 75 gr OTM does not."

"If a short barreled 5.56 mm weapon, such as the Colt Commando, LMT/Crane
Mk18 CQBR, HK416, HK 53, HK G36C, etc., is used with a 1/7 twist
75 gr Hornady OTM, 77 gr Nosler OTM, 77 gr SMK OTM, and 100
gr BH OTM loadings offer acceptable performance"
DocGKR on AR15.com
"For longer range engagements using precision weapons like the
Mk12 SPR or DMR rifles with faster 1/8 or 1/7 twist barrels, one of
the combat proven 5.56 mm (ie. 5.56 mm NATO pressure loads, not .223
SAAMI pressure loads which run about 200 f/s slower) heavy OTM
loadings are a good choice: the Barnes 70 gr TSX (Optimized
Hornady 75 gr TAP (#8126N) , Nosler 77 gr, or the
Sierra 77 gr Match King (Mk262 Mod1)."
Duty Loads" by Dr. Gary Roberts in pistol-forums.com
"...what is needed is a environmentally robust, thermally stable
combat rifle round with improved terminal performance, yet without
the need for the 600+ meter precision accuracy of Mk262 in the Mk12.
Such a carbine combat load needs to have a crimped and sealed primer,
sealed case mouth, cannelure, acceptable accuracy out to 300-400
meters coupled with good soft tissue terminal performance (early yaw,
good fragmentation, at least 12 inches of penetration coupled with
maximized tissue damage during the first 10 to 12 inches of travel in
The new Hornady 75 gr milspec OTM (#8126N) loading or
equivalent BH milspec 75 gr or Nosler 77 gr OTM loads are examples of
this type of combat ammo. Note, the Hornady 75 gr OTM load has a
proven combat record in use with certain U.S. SOF units for several
Also note that an ideal combat load should be relatively
blind to intermediate barriers, although at this time, no 5.56 mm
loads can fully meet this goal.
