WTF ??? It all boils down to is that a Wing Chun punch and a bullet's (projectile) ultimate goal is to end an confrontation quickly and effectively.After looking at Futsao's clip and Geezer's comment on "How to train a solid punch", I don't seems to remember anyone has cover the subject on the "terminal effects" of a punch, though I would ATTEMPT to give it a SHOT at it.
With limited knowledge and understanding of the subject matter, what outlined below is JUST my take, feel free to add what is relevant. If you think I had too many beers while writing this, you can present your own version, but PLEASE don't let this become another 100 page slam fest.
Without going into complicate scientific details, lets look at the moment of impact ... the fist or bullet hits the body parts, what is the effects of the generated power/force had on the target. There are many different way of punching to obtain an desired out come, lets look at the punch with and without the so called "push" as per Futsao and Geezer. It's an given that both will do damage to the intended target area, but to what extent?
#1 The "push" punch - at the moment of impact, part of the energy is expended in moving the target, leave what is left to do damage.
#2 Punch Without the "push" - very little energy is used to move the target, leaving the majority to do damage at the entry point and inside the target.
Mastery of #2 and the mechanics thereof, I'll defer it to the experts. I would like to see some one take this and run with it.
Here is where the bullet ... in relationship to terminal effect comes in. As with a punch, a bullet can do a little or do a lot of damage depending upon placement or design type, it could cause immediate or eventual death. Just an side note, I've been reloading my own ammo since the 80's, and still plenty left to learn.
The following are my simplistic views. Terminal effect of a bullet could be described as how much damage it can do, the damage it cause inside an target (body) is commonly called "wound channel or cavity". Different design bullet cause different wound patterns, lets look at lead (LRN) or full metal jacketed (FMJ) round nose and lead (LHP) or metal jacked hollow point (JHP), below are some of the breviate findings of some medicals examiners.
Using FMJ and JHP bullets:
#1 FMJ enter target, providing it did not hit any bone, may or may not deform and seldom expand more than its size, creates only an initial wound channel slightly bigger than its diameter, then taper off as it penetrate through and out the other side, taking all remaining energy with it.
#2 JHP by design will expand upon entering, some open up like a mushroom and some like a flower with razor sharp pedals, the larger size makes it harder to completely penetrate, therefore all available energy goes to create massive internal damage now called wound cavity. In cases where these pedals separate from the metal jacket and continues to travel, those fragments now will cause additional wound channels.
Just an side note, death can result from either bullet designs.
The common denominator of WC #2 and bullet #2 has to do with maximum damage by way of effective energy transfer into the target, some had referred this as energy/power dump (not the #2 we human do
).
