When Fackler evaluated the 5.45 round it showed that when the bullet was yawed as it passed through muscle, lung and bowel the only damage was the size of the bullet, there was no damage from the temporary cavity in these tissues. The temporary cavity would not damage these tissues without fragmentation.
If this is so, then why is the temporary cavity considered so significant in rifle wounding?
Why is it such a big deal to measure temporary cavities and develop the wound profiles if these large temporary will cavities have so little effect on most tissues?
The wound profiles show that a fmj rifle bullet (like the 7.62 NATO or a 30-06) has very little temporary cavity until it yaws. It could often exit the target before yawing. Yet these rounds are reputed to hit like a bolt of lightning and cause devastating unsurvivable wound damage.
