just a quick recap why i posted in this thread .
jim said
"And I agree re .22 rounds, I'd rather be shot by a 9mm or 557 round, at least they'll pass straight through rather than bounce around and turn your insides to mush like a .22."
he actualy meant a 9mm or a 5.56mm round as he corrected in a later post .
i had the audacity to disagree with both statements
1 that anyone would rather be shot with either a 9mm or a 5.56mm round and
2 that a .22 round bounces around ( inside a body or head ) and turns insides to mush.
in his last post with reference to me he put a link to some information that would prove his point ,,,,so my answers will come from that site that he linked to .
he then went on to say
"A .22 will enter the skull (for example) but it won't have the power to exit the other side, it'll simply bounce around inside causing havok, shredding the brain and /or organs depending where it hits, where as a more potent round will pass straight through, giving you a better chance if survival (yes, people can survive a through and through head shot!). Same for chest cavities. Anyone who knows anything about firearms knows this, simple physics."
well this depends on a number of factors ,,,the type of .22 round ,the distance it is fired from and where in the head or body it hits ,jim used skull in his for example ,,,
a .22 long rifle when fired with the muzzle in contact with the head according the the link says
"the bullet often exits the skull , though it may be found underneath the scalp,adjacent to the exit in the bone" it doed not say if fired from a rifle or a pistol
it then goes on to say
" at distant range .22 lr bullets penetrating the head can produce linear fractures of the skull whether the weapon used is a handgun or a rifle "
now i will put my hands up ( well maybe just one ) and say ,that my understanding was that in general a .22 would enter the head ,take its course through the soft matter and then stop fairly quickly ,maybe on the other side of the skull ,,,but according to the link
"in many handgun wounds of the head ,the bullet is retained either in the cranial cavity or beneath the scalp" and " as the calibre of a bullet increases the likleyhood of it perforating ( exiting ) also increases ,"
therefore a .22 is more likely to stay in the head ,and i agree .
there is a table that shows that out of 60 homicides ,which are generaly more distant shots. 6.6 percent of the bullets exited the head .
it also goes on to say
"as a general rule ,internal ricochet is more commonly associated with lead bullets and bullets of small calibre .Thus ricochet within the cranial cavity occurs most commonly with .22 lead bullets "
so i concede that this is in line with jims version ,although it dosent say anywhere that the round flies about in the skull like a silver ball in a pinball machine with tommy on the side buttons .
jim also says that a 9mm will pass straight through ,again more likely that a round from a handgun will stay in the head but does depend on other factors .
so on the issue of the .22 round ,,,i would say that my version is nearer to the truth than jims ,,,,although the bullet does enter and move around or ricochet in the skull it is limited to a degree
now on to the round that jim would rather get hit by ( as opposed to a 22 )
the 5.56 mm is a .223 derived round ,,,been around for a long time , but according to wikkiwotsit used by nato since 1980 ,,it wasnt designed to kill and maim as jim tells us in his history lesson,( but im sure he'ill say its a fact ) find byker28i's post for its history .
cavitation ,,,or temporary cavity ,,,when a bullet is travelling around 2700 and above ,and it hits soft tissue it leaves a shockwave behind it ,the tissue undulates or wobbles open and shut after the bullet has passed through ,this temporary cavity or hole can be as much as 11 to 12,5 times the size of the bullet diameter, and
so a 5.56mm bullet for a very short time ( 5 to 10 msecs ) puts a hole of around 60 mm through the ( in jims example brain ) this in turn creates a lot of pressure in the skull which will fracture and break the bone the chances of survival are ,,,,,,fairly unlikely ,,,,so why jim would prefer to get hit by a 5.56 instead of a .22 is totaly ridiculous ( although we both did agree that we would rather not get hit by anything )
i still stand by my original post .
"Sorry donut, you know nothing about firearms, best not comment anymore if you're going to make remarks like that."
as for jim making the above statement ,,,,,,
i have three shotguns ,a 45-70 martini henry ,two airguns ,and a .44 revolver ,used to have a .22 rimfire on an open certificate .
