You continue to avoid addressing my query: Can you provide a satisfactory source that shows that larger calibers and/or heavier bullets alone produce significantly more grievous wounds than smaller calibers and/or lighter bullets, especially for through-and-through shots? This is a keystone of the GPC theory, and I've not seen a shred of evidence to support it.
Alone? No, because nothing in ballistics and wound mechanisms works alone.
Shot placement. Angle of incidence. Target size. Target physique. Target cover. Target clothing/armor. Impact velocity. Bullet construction. Bullet size. Bullet weight. Sectional density. Bullet shape. Gilding material. Tissue structure. Tissue density.
All are percentages. I would have assumed that would have been clear, I'm not sure why you're asking for citations on this because it's basic internal ballistics is wound mechanism. Larger bullets make larger wound cavities, this is basic physics. Period.
Since you want some citations to this effect, I'll direct you to Hollerman, Fackler, Coldwell and Ben-Menachem's work on the subject.http://www.ajronline...r.155.4.2119095
"Two major mechanisms of wounding occur: the crushing of the tissue struck by the projectile (forming the permanent cavity), and the radial stretching of the projectile path walls (forming a temporary cavity)."
"Crushing of Tissue
A missile crushes the tissue it strikes, thereby creating a permanent wound channel (permanent cavity). Yaw is theangle between the long axis of the bullet and its path of flight. If the bullet is traveling with its pointed end forward and its long axis parallel to the longitudinal axis of flight (0° of yaw), it crushes a tube of tissue no greater than its approximate diameter. When the bullet yaws to 90°,e entire long axis of the bullet strikes tissue, and the amount crushed may be three times greater than at 0° of yaw.
Temporary Cavitation (Tissue Stretch)
"The maximal size of the temporary cavity occurs several milliseconds after the bullet has passed through the tissue [1 1]. Because forces follow paths of least resistance, tern- porary cavitation is likely to be asymmetric and spread out through tissue planes .
The temporary cavity caused by common handgun bullets is too small to be a significant wounding factor in all but the most sensitive tissues (brain and liver) . Center-fire rifle bullets and large handgun bullets (e.g., .44 magnum) often induce a large temporary cavity (10-25 cm [4-10 in.] diame- ter) in tissue. This can be a significant wounding factor, depending on the characteristics of the tissue in which it forms [4, 13]."
Why do you think a .223 is going to be better at making wounds at it's longer ranges than a heavier bullet?
Is .223 even effective to the ranges we're talking about here?
"Ballistic Properties and the Wound Produced
Recent controlled animal experiments with military rifle bullets  have clearly disproved the assertion that all tissue exposed to temporary cavitation is destroyed. These studies also show that not only does the 14-cm-diameter temporary cavity produced by the AK-74 assault rifle not destroy a great amount of muscle, but the sizable stellate exit wound it causes in the uncomplicated thigh wound ensures excellent wound drainage, which assists healing [1 4, 18, 19]. This is consistent with the pathophysiology of wound healing and the history of the treatment of wounds received in war [18, 19]. A history that the wound was caused by a “high-velocity bullet” does not mandate radical excision of the wound path.
The characteristics of the wounded tissue, the thickness of the body part, the point in the path of the bullet at which yaw or fragmentation occurs, and other factors strongly influence the wound produced. Bullets of equal wounding potential may produce wounds of quite different severity, depending on which tissues they traverse. Teh heavier, slower bullet crushes more tissue but induces less temporary cavitation. Most of the wounding potential of the lighter, faster bullet is likely to be used up forming a larger temporary cavity, but this bullet leaves a smaller permanent cavity. The heavier, slower bullet causes a more severe wound in elastic tissue than the lighter, faster bullet which uses up more if its potential producing tissue stretch (temporary cavitation). This tissue stretch may be absorbed with little of no ill effect by elastic tissue such as lung or muscle. In nonelastic tissue, such as liver or brain, the temporary cavity produced by the lighter faster bullet can produce a more severe wound."
So far, you have shown nothing to back up these claims, and when pressed you divert to topic to external ballistics and handgun cartridge choice.
Handgun bullet choice? Sorry, no, I've been talking about bullet wounding mechanisms. It's the same mechanisms across the board with differences based upon the differences involved. Handgun cartridge choice in some respects is specialized but overall it's the same mechanism. Rifle bullets that expand are going to create larger wound channels due to greater energy and penetration depth. Rifle bullets are going to be more effective because you can reliably hit targets with the faster bullets than with even injury optimized pistol bullets. This is why pistol caliber sub machine guns are poor weapons for ranged combat. You have a great wounding capability but a poor hitting capability.
Hitting the target is the first step in making a wound. Getting good terminal effects is next. If you're firing 5.56 at long range and it's not yawing because of typical target profiles and it's certainly not fragmenting due to insufficient velocity then it's not working is it? A larger bullet, fired at the same target at longer range which hits will create a larger wound profile.
Hey, E5M, when you guys went out sniping did you prefer 7.62mm or 5.56 for your sniping? Why?
