Military rifle temporary cavity effects

[gunnie]

time may be more of an issue than stretch cavity, amount of wound damage, potential for blood loss...etc

except a disruption of the central nervous system, NO weapon fired unsupported from a human being is a sure thing.

the reason is time. the difference between getting a heart and/or lung shot on a deer, or an armed hostile is time.

even with a mortal wound, many have ruined their adversary's entire day with aimed fire before they had time to realize they were dead.

HP, "dum-dum" FMJ, fragmenting, all non issue. it's either high placed CNS, or how much time YOU have to tag the target repeatedly until the threat ceases.

I understand that for the most part, stretch cavity effects will have little or no contribution to incapacitation.

I'm trying to get a general idea of the nature and extent of the damage that may result in elastic tissues (muscle, lung) from the stretch cavity that would be created by a yawing .30 caliber fmj projectile.

Would such a stretch cavity in elastic tissues amount to just a large nasty bruise surrounding a portion of the wound track (like the bloodshot tissue described by hunters)?

Will the permanent cavity end up being larger than the bullet's dimensions as a result of the temporary cavitation?

For anyone who has seen them, Dr. Fackler's AK74 photos (Deadly Effects DVD, also on the internet) showed the bullet next to the wounds in the lung and muscle shots. The wound appeared to be a little larger than the length of the bullet in the lung. In the muscle wound the difference between the bullet length and the wound was even more. Would this be because of tissue that was stretched and did not recover?

I could not tell from these photos how bruised the surrounding areas were.

Even though the stretch effects won't physically incapacitate, it seems they could still immediately contribute to impairment or loss of function.

I'll word my original post a little differently.

(1) FMJ round fired from an M1 Garand. Bullet is yawed to 90 degrees as it passes through a lung. With the permanent cavity and the stretching of the temporary cavity, what would be the most damage to the lung that might occur? Just a .30 caliber hole or more extensive (like entire lung turned to jelly)?

(2) FMJ round fired from an M1 Garand. Bullet is yawed to 90 degrees as it passes through muscle. With the permanent cavity and the stretching of the temporary cavity, what would be the most damage to the muscle that might occur? Just a .30 caliber hole or more extensive (fist sized area of pulped nonviable muscle)?

I know it is highly variable, but what would be an approximate result?
