a good read and link to keep, better have time though its long.

It's a hydraulic shock. It's the energy transfer from the projectile to the less dense softer tissue (IE. mussle tissue or organ tissue) in the body.

If you shoot it through the lungs, would it then be pneumatic shock?

It's the most important.. if something is possessing no KE, it wont create a wound channel. Penetration requires energy release..bullet runs out of energy it stops. Could be in the ground on the other side of the critter, under the skin on the exit side of the citter, or in the shoulder on the entrance side. This takes into account bullet design as well due to high weight retention still possessing intial energy.

Interesting the Theory's going on there but the author is very choppy and non consitant.

an arrow has about 60lb ke and tipped with a razor broadhead it will kill better than an fmj witt 1500lb ke so tell me how its the most important

I have a .243 and like it. Ammo is easy to find.

Fairly simple if the fmj hits a major attery like an arrow does same effect, except there will be more tissue damage cause by the speed of the impact by the bullet.

2 different methods of killing... or else you could kill a deer with that same arrow at 400yds like you could the FMJ.

i doubt it but lets say your right.
shoot a deer in the leg with a 300 mag delivering 3000 ft lbs ke,
so again hows ke the most important factor determining the lethality of a projectile

come on your reaching, the wound channell is the sole determing factor of the lehality of a projectile
hit a deer in the gut and your KE didnt kill squat

Don't have KE and you can't have a wound channel.

Anyways... I have both and have killed animals with both. Whitetail, axis, and coyotes with both as well as hogs and javelina with 7-08, and seen several nilgai killed with 7-08. My 7-08 does have noticeably more recoil and my 243 but from talking to others I think it has more to do with the fact that it is a Browning. I know for a fact that other rifles by different manufacturers makes a difference in recoil since other members of my family also have both calibers but both in Remington and I have shot them with less felt recoil. All that being said I can honestly say either one is fine for hunting in Texas and with a decent recoil pad for a kid just fine. I would want a larger rifle caliber if I knew I was going to Colorado to elk hunt or some other bigger than deer size animal.

hehehe that is true though

What's to doubt? anything hit in a major artery will die whether it's a knife or bullet. I never said knetic energy is so important but you need a fair amount to help penetration or a bullet built well enough to compensate. The KE will help poorly built projectiles to reaching the vitals and still being able to dispatch the animal.

An arrow typically kills from hemorage due to the cut made by the arrowhead be that watever material. A bullet on the though is more like a blunt force instrument tearing and bludgenoning its way thruough. Both take sufficient KE to cause enough damage to cause the death of the intended animal. Wether that is 40ft/lbs with an arrow or 250ft/lbs with a Hornet

What is also true is that it is hard to kill without a wound...

So which one is MORE important? Wound channel, no doubt. 22lr through the brain has much more potential to kill than a .338LM through a toe.

someone gets it

your correct but I like to say its velocity not KE,
KE is just a mathmatical derivative of velocity. Velocity on the other hand is measurable quantum

Both handguns and rifles have a temporary cavity and a permenent cavity. Handguns generally (unless talking about certain uber magnum) the temporary cavity doesn't damage the tissues that much, and the permenent cavity is the main mechanism of damage.

Rifles, on the other hand, mostly have enough energy to do damage with their temporary cavity. Thats why a good shot will turn the lungs and heart into mush. Its not that the wound channel was 5" wide.

Bullet construction determines how bullets hold together through tissue.

Knetic energy is not a derivitive it's the energy an object carries it works directly with inertia which all very with different velocity's.

can you physically measure kinetic energy of a bullet.
I can weight a bullet and i can measure its velocity
when we do the math isnt that realy potential energy
ahhh my head hurts this is mucho petho

Maybe you should specify that the "location" of the wound channel is the most important factor in the lethality of a projectile.

If you hit a deer in the gut with a .22 versus a .300 Mag I would bet the KE dispersed would be an important factor to the deer and would be much less likely to survive the shot from the .300. The size of the wound channels are related to the cavitation and hydrostatic shock delivered by the bullet, not just the size of the projectile.

No?

ΔK = W = FΔs = maΔs

v2 = v02 + 2aΔs ⇒
aΔs = v2 − v02

ΔK = m ⎛
⎝ v2 − v02 ⎞
⎠

ΔK = 1 mv2 − 1 mv02

ΔK = W = ⌠
⌡ F(r) · dr = ⌠

ΔK = 1 mv2 − 1 mv02

K = ½mv2

KE is determined by use of a mathmatical formula just like velocity.

They directly relate VG's wording to me points that it's not a real thing which it is, just takes a known formula to calculate.
