180 RULE: When
on the firing line – either at a practice range or during competition –
the muzzle of the gun must be pointed downrange. The 180 rule
requires that the gun not be turned laterally more than 90 degrees left or
right (a total of 180 degrees, hence the name of the rule). All
organizations and ranges should observe this rule.
"Government" model 1911 .45 ACP semi-automatic handgun. Originally
this design came from Colt but there are now many manufacturers making
guns of this type. It is an extremely popular choice for action shooting
and self-defense in the United States.
22 LR: .22
caliber "Long Rifle" but this is also a pistol ammunition. 22 LR is
by far the most popular rimfire cartridge for handguns.
.222 MAGNUM: When comparing the 222 Magnum and the
223, the case size appears to be nearly identical. However the 222 Magnum
is about 1/10" of an inch longer and holds about 1/2 to 1 grain more
powder, 223 cartridges should not be fired in the 222 Magnum, as the case
dimensions are different and the cases are likely to rupture, possible

and arms that are caliber .233 Remington. Usage: My new rifle is a

.223 REMINGTON: The
caliber .223 Remington began as a military cartridge in 1957 (evolving
into the current 5.56 NATO cartridge used in the U.S. Army M-16 and many
other assault rifles) and was later introduced by Remington as a
commercial round. The cartridge is now chambered by numerous manufacturers
in a variety of firearms. Most popular of those being "Americas Rifle" the
AR-15 in its many forms and spin off model numbers. Because military
surplus brass is readily available and inexpensive, the 223 is more
popular than the 222 Magnum, and its popularity is still growing.

The 223 is an excellent choice for varmint hunters, plinkers, police
carbine and self-defense and the types of commercial actions in which this
cartridge is available, ranges from the AR-15 semi automatic to the
expensive bolt action rifles made by almost every gun company on earth.
Couple this wide assortment of firearms with a superb selection of 22
caliber bullets and the 223 is my choice for any 22 caliber use. Some
disagree and love to disparage the .233 - most of them have never been
shot at or used a M-16 in combat. See the Mouse that roared article below

About the "Mouse
Clarifying some popular gun shop and Internet fables
There has been a great deal of resentment surrounding the .223
Remington cartridge since its inception during the 1950s, and
continuing right up to this day with no less, and no more, an eminence
than Jeff Cooper disdainfully dismissing it as "a mouse gun round."
Formally introduced in 1964 as the military's Ball Cartridge M193
round for the experimental semi-automatic and light automatic rifles
designed by Eugene Stoner, L. James Sullivan and Robert Fremont of
ArmaLite Division of Fairchild Engine and Airplane Corporation, the
5.56 X 45mm (nee .222 Special) or 5.56mm NATO had evolved
along parallel lines with the .222 Remington Magnum (nee .224
Springfield) cartridge, but with roughly one grain less of case
(The "triple deuce magnum," a prototypal military round for use in
light combat arms, had itself been developed jointly by Remington Arms
U.S. Springfield Armory¹
in the mid-'50s as part of
Although the military had had its problems with the replacement for
its venerable M1 Garand, the M14 chambered in 7.62 X 51mm, hard corps
types, feeling that there was something unseemly about a fighting
rifle of anything less than .30 caliber, denigrated the 5.56mm at
practically every opportunity, and there is considerable evidence that
the Army Ordnance Corps³
(which had built the M14 itself) actually tried to rig the U.S.
Military procurement tests to the disadvantage of the AR-15/5.56mm
combination. That the 5.56mm/.223 Remington has succeeded as the
military's designated round for its infantrymen for as long as it has
may be viewed as something of a minor miracle.
The .222 Special, now renamed the .223 Remington so as to avoid
confusion with the other two "triple deuce rounds," was released
commercially as a sporting arms cartridge when the company for which
it is named brought out their Model 760 slide action rifle in that
chambering for the 1964 season. The gun writers of the day for the
most part gave it short shrift, arguing that it was "wimpier "than the
already established .222 Rem. Mag., and that the geometry of the
cartridge with its relatively short neck was violating a cardinal
As more carbines and rifles were introduced for
the .223 Remington, the .222 Remington Magnum has all but disappeared.
(So too, for all practical purposes, has the original .222 Remington,
once the standard for benchrest competitors who have abandoned it in
wholesale numbers for the fat little PPC cartridges of .22 and 6mm
designation which Ferris Pindell and Dr. Louis Palmisano introduced to
great acclaim in the early '70s.)
Undoubtedly what has solidified the .223 Remington's place in the
hierarchy of small bore rifle chambering has been the enormous
popularity of Sturm, Ruger & Company's Mini-14 (and subsequent "Ranch
Rifle" edition) and the many variations of the Colt's AR-15, the
semi-auto version of the military M16, the celebrated, ofttimes
notorious, but ubiquitous "black rifle" of Vietnam.
Background on the 5.56mm
In the aftermath
of the Second World War, the United States Military determined that it
had a requirement for a detachable-magazine rifle with a
fully-automatic capability. After a less-than-satisfactory honeymoon
with the 7.62 NATO/M80 (a commercial version of which was released by
Olin as the .308 Winchester), those involved in the Small Caliber/High
Velocity (SCHV) program at Maryland's Aberdeen Proving Ground agitated
for a lightweight, select-fire rifle firing... no surprise here!... a
smaller, mid-power, high-velocity cartridge. (Coincidentally, within
this same period, the military of many other countries were
experimenting with sub-.30 caliber guns that were controllable in
full-auto, and allowed more rounds to be carried.
Into the M1 Garand/M14 breech stepped small arms designer Gene Stoner
of ArmaLite. Having designed the 7.62x51mm AR-10 rifle, Stoner
listened when General Willard G. Wyman, Commanding General of the U.S.
Continental Army Command (CONARC) suggested that a scaled down version
might be looked upon with favor by the SCHV program. ArmaLite
engineers Jim Sullivan and Bob Fremont thereupon reduced the AR-10
around the hot varmint cartridge of the day, the .222 Remington.
In the early-to-mid-'50s there had been three .22 caliber cartridges,
all "stretched" versions of the popular "triple-deuce," which were
vying to be the next military round:
- .224 Winchester
- .224 Springfield
- .222 Special,
testing by the U.S. military, it was apparent that the .222 Remington
developed excessive pressures when loaded to meet the Army's ballistic
requirements. At the same time, the pair of .224s also fell by the
wayside. While the experimental .224 Springfield had the increased
power sought, it was felt that its geometry would have prevented
positive feeding in an automatic self-loading rifle. Stoner's .222
Special case was then simply lengthened into the 5.56x45mm cartridge
(a/k/a .223 ArmaLite) and released commercially as the .223 Remington
with virtually identical exterior ballistics as the .222 Remington
After U.S.A.F. General Curtis LeMay got a look at the scaled down
AR10, AR15, and was impressed enough to have the "black rifle" adopted
by the Air Force, the rest of the military gradually fell into line,
aided in no small amount by continuing problems with the M14 program.
Designated the M16, the Stoner-Sullivan-Fremont gun survived
everything from ammo-related problems (Winchester's curious selection
of propellants which caused reliability problems in the rifle's
finicky gas system) to invidious references by traditionalists to its
evolutionary plastic appurtenances ("Weapons by Mattel"), and went on
to become one of the most recognizable icons of the Vietnam war.
Not to be confused with the present day commercial enterprise in
Geneseo, Illinois which in the mid-'80s had appropriated the then
defunct Government arsenal's famous name.
².- Project SALVO, a precursor to
Special Purpose Individual Weapon [SPIW] project of the early
'60s, explored numerous schemes of enhancing hit probability such as
multiple barrels, multiple projectile loadings including flechettes,
and "small-caliber, high-velocity" (SCHV) cartridges the likes of the
.224" wildcats from G.A. Gustafson (a cut-down .222 Remington
chambered in a modified M-2 Carbine) and William C. Davis Jr. (a
necked down .30 Light Rifle [T65] case).
³.- Having fought so hard for the
7.62x51mm standard, the T65 cartridge and the T44 (M14) rifle,
Ordnance Corps officials could not afford to allow competing projects
to cast doubt on their decisions and usurp their authority. This is
why potential SCHV projects from within AOC were axed by Dr. Frederick
H. Carten. These included Gustafson's and Davis' proposed intermediate
.224" cartridge, along with the Springfield Armory prototype rifle
chambered in .224 Springfield. In contrast, Gustafson's work on the
modified M-2 Carbine had been allowed to proceed unencumbered by
politics since it didn't threaten the idea of a "full-power" infantry
rifle. Instead, it was to provide a replacement for the M-2 Carbine.

the SS109 name has stuck just like ".30-06" stuck in the U.S. Army.
"5.56mm NATO Ball" describes a specific cartridge, not a class of
cartridges. The projectile is roughly 62 grains in weight and is
projected at about 3100 fps at the muzzle. Lots of dimensional and
pressure standards, too. 5.56x45 describes a class of cartridges which
can be anything. U.S. M193 Ball is 5.56mm Ball, but it isn't "5.56mm
There is a difference between "5.56mm NATO Ball" and the commercial

5.56 NATO vs SAAMI
.223 REMINGTON CHAMBERS
We are often asked whether our rifles feature NATO (North Atlantic
Treaty Organization) or SAAMI (Small Arms and Ammunition
Manufacturers Institute) standard chambers, and whether it makes any
(SAAMI standard) and 5.56mm (NATO standard) rifle chambers are
almost identical. The difference is largely limited to the “freebore,”
the cylindrical space in front of the case mouth, and the “lead” or
“leade,” the the tapered region that eases the bullet into full
engagement with the rifling. NATO and SAAMI cartridges can
normally be used interchangeably with no problem.
The SAAMI chamber
features less freebore and a tighter leade, which normally provide
better bullet fit and match-grade accuracy than the NATO chamber.
It is wonderfully suited to match bullets.
rounds of NATO ammunition have been fired safely in Eagle Arms' and
ArmaLite’s SAAMI chambers over the past 15 years. Occasionally a
non-standard round (of generally imported) ammunition will fit too
tightly in the leade, and resistance to early bullet movement can
cause elevated chamber pressures. These pressures are revealed
by overly flattened or powder stains that reveal gasses leaking
around the primer.
The first few
rounds of ALL ammunition, from whatever source or lot, should be
checked for pressure and other signs of defect before firing large
quantities. If you have a problem, you can generally bet that
the ammunition meets neither SAAMI nor NATO specifications.
adopted a practice of using a special, modified SAAMI chambers in
its stainless steel match barrels. This chamber is better for
match use than the NATO chamber, but fires the NATO ammunition
perfectly. We use the NATO chamber in all moly (phosphated)
and chrome-lined barrels.
AR-10® rifles are all chambered with 7.62mm NATO chambers.
.308 Winchester (SAAMI standard) ammunition functions perfectly in
the 7.62mm chambers.

America's Great Guns
M4 Carbine shown with Trijicon ACOG
The M4 Carbine is a lightweight, gas operated, air cooled,
magazine fed, selective rate, shoulder fired weapon with a
collapsible stock. A shortened variant of the M16A2 rifle, the
M4 provides the individual soldier operating in close quarters
the capability to engage targets at extended range with
accurate, lethal fire. The M4 Carbine achieves over 80%
commonality with the M16A2 Rifle and will replace all M3 .45
caliber submachine guns and selected M9 pistols and M16 rifle
SPECIAL FEATURES AND PERFORMANCE
The M4/M4A1 carbines serves with American Special Operations
Forces, most notably the U.S. Army Rangers, Marine Force Recon
and the U.S. Navy SEAL Platoons. And the Army has begun
general issue of the M4/M4A1 to main force units, like the
82nd Airborne and 101st Airborne. The M4/M4A1 carbine is
replacing the M16A2 and sometimes the M9 Beretta pistol in the
troops' hands because the rifle gives up little to its larger
parent in terms of range and lethality while being much
handier and more compact.
After the military conflicts in Panama, the Persian Gulf and
Somalia, the need for a shorter version of the M16A2 again
appeared. Colt engineers shortened the barrel back to
14.5", and mill contoured the barrel to mount the M203 grenade
launcher and added a modified version of the collapsible,
sliding butt stock of the earlier XM177 series rifle.
They also created a new upper receiver using a modular sight
mounting system for use on a sub-variant. In August, 1994,
both variations were adopted. The United States Carbine,
Caliber 5.56mm NATO, M4 uses the new barrel and collapsible
buttstock, but was first issued with the standard M16A2 upper
receiver and sights to streamline production, though it now is
made with the new modular upper receiver.
The M4 could be fired either semi-automatically or with three
round bursts. The United States Carbine, Caliber 5.56mm NATO,
M4A1 uses the new barrel and collapsible buttstock and the new
upper receiver for mounting a wide variety of sights,
including night vision and infrared aiming lasers, as well as
the standard sights on a detachable handle, but it is also
capable of fully-automatic fire, like the M16A1.
The M4 and M4A1 have been produced by Colt Additionally, the
military has begun procuring both the M16A3 and M16A4. The
M16A3 and the M16A4 are identical to the M16A2, but both have
the modular upper receiver. The M16A3 is capable of fully
automatic fire, like the M16A1, while the M16A4 uses the
M16A2's three-round burst mechanism. Additionally,
several types of optical sights have been developed for
the modular upper. The new sights include a "red dot," close
combat sight, much like civilian IPSC-style competitors use to
quickly index to a target and an infrared thermal sight, to
allow a soldier to see a target at night from body heat.

M4 Sherman Tank: The M4 Sherman
was an American tank used during the Second world War. Many varieties were
made, but the most common was the M4A3 which weighed 31.57 tones and had a
crew of five. It was fairly thickly armored, up to 108mm and had a
75mm gun plus a co-axial machine gun in a fully traversing turret and an
extra ball mounted machine gun in the hull front. As with the M3 Lee
Tank an additional machine gun was usually fitted to the commander's
cupola. The M4A3 was powered by a Ford 450bhp V8 engine which gave it a
top speed of 42kmph and a range of 160km.

barrel and includes a folding stock. The M6 Scout is marketed by
Springfield as a survival rifle. It is issued to American Air Crews
and is integral to the survival evasion and escape equipment packaged in
the ejection seat and survival packs for air crew. It is not
designed as a battle field weapon, rather to use for acquiring small game
for consumption in a survival situation.
M9: The M9 is a full sized 9mm
semi-automatic pistol manufactured by Beretta, and adopted by the American
military in place of the M1911. The M9 is basically the same as the
model 92 Beretta.
