If you experience that this is dangerous incorrect information to say and so i will add to my previous mail that this is my opinion and not fact.
Cheers for the correction.

factors and the other physiological damage. People are oftentimes chop-chop
psychologically incapacitated by minor wounds that are not immediately
physiologically incapacitating. Psychological factors are too the
reason people tin receive severe, even non-survivable wounds and
continue functioning for short periods of fourth dimension. Up to 50 percent of
those individuals rapidly incapacitated by bullet wounds are probably
incapacitated for psychological rather than physiological reasons.
Psychological incapacitation is an extremely erratic, highly variable,
and completely unpredictable man response, independent of any inherent
characteristics of a particular projectile.
The caste and rapidity of any physiological incapacitation is
adamant by the anatomic structures the projectile disrupts and the
severity of the tissue damage caused by the bullet. Physiologically,
immediate incapacitation or decease can only occur when the encephalon or upper
spinal cord is damaged or destroyed. The tactical reality is that in
gainsay, opportunities for military personnel to have precisely aimed
shots at the CNS of enemy combatants is rare due to high stress
unexpected contact marked by rapid fleeting movements, along with
frequent poor visibility on the battlefield including utilise of cover and
concealment. Thus the reduced likelihood of frequent planned CNS
targeting in gainsay atmospheric condition. Absent CNS damage, circulatory system
collapse from severe disruption of the vital organs and blood vessels in
the torso is the but other reliable method of physiological
incapacitation from modest arms. If the CNS is uninjured, physiological
incapacitation is delayed until blood loss is sufficient to deprive the
brain of oxygen. Multiple hits may be needed before an individual is
physiologically incapacitated. An individual wounded in whatever area of the
body other than the CNS may physiologically exist able to continue their
actions for a short period of time, even with non-survivable injuries.
In a 1992 IWBA Journal newspaper, Dr. Ken Newgard wrote the post-obit about
how claret loss effects incapacitation:
"A 70 kg male person has a cardiac output of around 5.5 liters per minute.
His claret volume is about 4200 cc. Assuming that his cardiac output tin
double under stress, his aortic blood flow can reach eleven Liters per
infinitesimal. If this male person had his thoracic aorta totally severed, it would
take him 4.6 seconds to lose twenty% of his total blood volume. This is the
minimum amount of time in which a person could lose 20% of his blood
volume from one bespeak of injury. A marginally trained person can fire at
a charge per unit of two shots per second. In 4.six seconds there could easily exist 9
shots of return fire before the attacker's activeness is neutralized.
Note this assay does non business relationship for oxygen contained in the blood
already perusing the encephalon that will go along the encephalon functioning for an
even longer period of time."

whatsoever: the archway and exit holes were well-nigh 4 mm across, and
punctate. X-ray films showed intact bones, no bullet fragments, and no
evidence of significant tissue disruption acquired by the bullet'due south
temporary cavity. The bullet path passed well lateral to the femoral
vessels. He was back on duty in a few days. Devastating? Hardly. The
wound profile of the M193 bullet (page 29 of the Emergency War
Surgery—NATO Handbook, GPO, Washington, D.C., 1988) shows that most
often the bullet travels about five inches through flesh before
showtime pregnant yaw. Only about xv% of the time, it travels much
farther than that before yawing—in which case it causes even milder
wounds, if it missed basic, guts, lung, and major blood vessels. In my
experience and enquiry, at least as many M16 users in Vietnam concluded
that it produced unacceptably minimal, rather than "massive", wounds.
After viewing the wound profile, recall that the Vietnamese were small-scale
people, and mostly very slim. Many M16 bullets passed through their
torsos traveling mostly point forwards, and caused minimal damage. Virtually
shots piercing an extremity, even in the heavier-congenital Americans, unless
they hit bone, caused no more than damage than a 22 caliber rimfire bullet."

Annotation that many consider M193 to wound better than M855.
Then while having a stash of M855 is never a bad thing (I take at least a couple grand rounds at all times of the stuff), it definitely isn't my first pick nor would I recommend it first and foremost as a cocky-defense round. You can psychologically incapacitate someone with a .22LR or .25ACP but that doesn't brand it the best round either.
Carry on.
