So why is the velocity number there??? why is it they post when the bullet is at is magic velocity.. So the bullet does its job. Exspanding to its max potential to transfer all or the max energy to create the biggest wound channel possible to shut down organs asap.

So your velocity number is only one part of the equation. They don't need to confuse you with all of that. They just state were there bullet preforms best to do the job.

You are only rite to an exstent.  Also Jimmy is a great guy that has forgot more than most know. ;)

The velocity number is there becuase it gives you a range (min and max) at which the bullet performs the best. It is velocity that creates the wound channel, not energy.
There are many different roads that lead to the same place. Some are easy, some are difficult. Looking at velocity is the easier road.
No further comments about Jimmy and what he knows, or has forgotten...

Here is  a read on Energy and the effects .. i have done lots of Hydrostatic Shock shots over the years

enjoy link provided

Hydrostatic shock


From Wikipedia, the free encyclopedia


 Jump to: navigation, search


 



Average time until incapacitation decreases rapidly with pressure wave magnitude as magnitudes approach 500 psi (3,400 kPa). See: Links between traumatic brain injury and ballistic pressure waves originating in the thoracic cavity and extremities. Brain Injury 21(7): 657–662, 2007.
Hydrostatic shock or hydraulic shock describes the observation that a penetrating projectile can produce remote wounding and incapacitating effects in living targets through a hydraulic effect in their liquid-filled tissues, in addition to local effects in tissue caused by direct impact.[1][2] There is scientific evidence that hydrostatic shock can produce remote neural damage and produce incapacitation more quickly than blood loss effects.[3] Proponents of cartridges that are "light and fast" such as the 9x19mm Parabellum versus cartridges that are "slow and heavy" such as the .45 ACP round often refer to this phenomenon.
 
Human autopsy results have demonstrated brain hemorrhaging from fatal hits to the chest, including cases with handgun bullets.[4] Thirty-three cases of fatal penetrating chest wounds by a single bullet were selected from a much larger set by excluding all other traumatic factors, including past history.
 

In such meticulously selected cases brain tissue was examined histologically; samples were taken from brain hemispheres, basal ganglia, the pons, the oblongate and from the cerebellum. Cufflike pattern haemorrhages around small brain vessels were found in all specimens. These haemorrhages are caused by sudden changes of the intravascular blood pressure as a result of a compression of intrathoracic great vessels by a shock wave caused by a penetrating bullet.
 
— J. Krajsa[5]
 
It has often been asserted that hydrostatic shock and other descriptions of remote wounding effects are nothing but myths. A recent article in the journal, Neurosurgery, reviews the published evidence and concludes that the phenomenon is well-established.
 

A myth is an assertion which has either been disproven by careful experiment or for which there is no historical or scientific evidence in cases where it is reasonably expected. Belief in remote effects of penetrating projectiles may have originated with hunters and soldiers, but their reality is now well established in a broad body of scientific literature...

I see we are still having some difficulty with this. 45ACP vs 9mm in people? WTF?

This is as simple as I can make it.
A fella hits a block of balistic gel as hard as he can with a baseball bat. That action creates both velocity, and energy. In fact, the blow delivers a pile of energy to the block. The reslut is that the gel block deforms, and shakes, and returns to much of it original shape.
Now, launch a screwdriver, at the same velocity as the baseball bat, at that same piece of gel. This action also creates both velocity and energy. The screwdriver will pentrate the gel, and velocity will create a wound channel, and deform the gel. The result will appear fairly grusome, as the screwdriver will be burried completly in the gel.
Think of it this way: Velocity creates the wound channel. Energy deterimines how deep it goes, as does bullet type, construction, etc. The two are realated, but not linear. In a hunting sense, I can make up for a lack of energy, by shooting a lighter bullet, faster. This is the entire concept behind Barnes, and other solid copper bullets.
There are reasons why militaries selected the lighter, faster 5.56 round over the slower, heavier .308 round. The main one was the effectivness of the increased velocity at creating massive wound channels.
Another was just actual weight savings, meaning more ammunition could be carried.
Bullets companies publish a window at which their bullets will perform. Lets use a Nosler Accubond. Nosler does not list a Maximum number, so that really tells us that in the weights that are availible, it can't be pushed fast enough to fail. The minimum is listed at 1800fps. A quick refernece to my known (measured) velocity tells me that the bullet will perform out to 725 yards.
If it has enough velocity to expand, then it will have enough energy to kill. How much energy does it take to kill an animal? I don't know, and I don't care, because the velocity number tells me the bullet will work, and at what distance. It is the much easier, more dependable path to get the desired results.

I see you are still missing the target.  Velocity itself is the measure of speed.  It needs a something to measure and then that something needs some mass in order to do something with the velocity.  Some mass in motion with some velocity then has some kinetic energy.

If the something is a bullet and the velocity is 2800 ft/sec cased by the bullet being shot from a gun then there is kinetic energy with it. (lets call it foot/pounds of energy)  When that hits ... lets say an apple then the energy is imparted to the apple as the bullet makes a hole through the apple.


To say it is all or only velocity is like saying a car is all about its engine and the transmission and wheels are not important.

I am disapointed.
Do any of you know how to read? Read my post again, carefully.

I am going to ask some questions. Please, actually read, then answer them.

Exactly how much energy does it take to kill a 200 pound deer?
Exactly how much energy does it take to kill a 1200 pound moose?
Does the amount of energy it takes to kill the above mentioned animals change, as their weights change?
If the above answer is yes (hint), how do you propose to get said animals on a scale before shooting them?

Another hint. I seldom miss, and I never guess. I am very aware of what velocity is, and what it does. Why do you think I am trying so hard to explain it to everyone?
I clearly stated in my last post that velocity and energy are related. I tried my best to explain how, using an example, I thought, that should be understood by anyone with opposing thumbs, and the wherewithal to pull a trigger. I see that I have failed. This is what disapoints me.
As a hunter and a shooter, velocity should hold far more value to you than energy does. It is the easiest way to predict results. You can do it with energy numbers, of course, but it is a much more difficult thing to do, and far less accurate. This is why bullet manufactures do not post up recommended energy numbers, and do post up recommended velocities.
Can I suggest that it may be time to start reading, and perhaps asking some questions, instead of sitting on the couch reflecting about how hurt your feelers are? Please feel free, using facts and data, to prove me wrong.

Just for "fun" see below:


I see you are still missing the target.  Velocity itself is the measure of speed.  It needs a something to measure and then that something needs some mass in order to do something with the velocity.  Show me a calculation of speed, that has anything to do with energy?Some mass in motion with some velocity then has some kinetic energy.

If the something is a bullet and the velocity is 2800 ft/sec cased by the bullet being shot from a gun then there is kinetic energy with it. (lets call it foot/pounds of energy)  When that hits ... lets say an apple then the energy is imparted to the apple as the bullet makes a hole through the apple. It is not energy alone that puts the hole in the apple, it is the speed at which that energy is delivered. I can put just as much, and more energy on that same apple as that bullet does, and never manage to put a hole in it.


To say it is all or only velocity is like saying a car is all about its engine and the transmission and wheels are not important. Bulldozers deliver a lot of energy, but I don't see them winning very many Formula 1 races

Again, usings facts and figures, please feel free to prove me wrong. More importantly, put your mind right, and try and learn something that will only help you understand better what exactly is happening when you pull a trigger.

How do you calculate kinetic energy? This will prove your own theroy incorrect.

I was hoping not to go there, but again, there may be learning afoot!!! ;)

Lets have a look at what Wiki tells us, the underlined bits are important:

"In classical mechanics, the kinetic energy of a point object (an object so small that its mass can be assumed to exist at one point), or a non-rotating rigid body depends on the mass of the body as well as its speed. The kinetic energy is equal to the mass multiplied by the square of the speed, multiplied by the constant 1/2.
 
When you throw a ball (or shoot a bullet from a rifle), you do work on it to give it speed as it leaves your hand (rifle barrel). The moving ball(bullet) can then hit something and push it, doing work on what it hits. The kinetic energy of a moving object is equal to the work required to bring it from rest to that speed, or the work the object can do while being brought to rest: net force × displacement = kinetic energy.
 
Since the kinetic energy increases with the square of the speed, an object doubling its speed has four times as much kinetic energy. For example, a car traveling twice as fast as another requires four times as much distance to stop, assuming a constant braking force. As a consequence of this quadrupling, it takes four times the work to double the speed."

Fairly serious stuff eh fellas? Start factoring in surface areas, bc numbers, and a whole bunch of other stuff, and things can get more than a little sporty. As I said before, and as above, I can make make energy with speed. There is no energy in a speed calculation.

I don't think anyone is arguing with you,, well other than the intense conversation you are having with yourself.. Some are just trying to explain to you,, they are tied together,, you can't have one without the other. Again,, energy creates the velocity and in the end the velocity delivers that energy to the intended target. Just the velocity on its own does nothing in the end it's the energy created by that velocity that kills. Again,, what has more energy a 22-250 at 4000 fps or 300 rum at 3200 fps.. See the velocity does nothing on its own it has to be applied to some mass which in turn delivers the energy. The more mass combined with the velocity creates more deliverable energy.. Again one is nothing without the other.

But I'm done with this one you are starting to take this one sideways,, too bad it was a good topic..

Good luck with this Rman.

Thanks!

I almost always put myself in a position to make my own luck.
This won't be any different.
Hopefully some learning can get done, and people will have a better understanding of why shit happens the way it does, and why some shit gets done, that most think can't be done. I have been doing "impossible" for quite some time. It is never not entertaining, and I'm not even that good.

I don't think anyone is arguing with you,, YOU, are arguing with me. You don't understand what I am trying to explain. I can't draw you crayon pictures to explain it to you. You have to READwell other than the intense conversation you are having with yourself.. I thought I was talking to you?Some are just trying to explain to you,, they are tied together,, you can't have one without the other. I have already said this, several times. Yes, they are related, but not how you think. Also, there is zero energy in calculating speed. NONE. There is however, a speed caculation for energyAgain,, energy creates the velocity Energy does not create speed, speed creates the energyand in the end the velocity delivers that energy to the intended target. Just the velocity on its own does nothing in the end it's the energy created by that velocity that killsThis, is wrong. Think of it this way, speed does the killing, energy determines how dead stuff gets. Again,, what has more energy a 22-250 at 4000 fps or 300 rum at 3200 fps.. Did you read the example of the bat and screwdriver? The RUM has more energy, yet it will not punch a hole in the steel plate, as shown. Yet the 22-250 will. This is esentially why speed is far more important than energySee the velocity does nothing on its own it has to be applied to some mass which in turn delivers the energy. The more mass combined with the velocity Again, you have it backwards. The more speed that is appiled, the more energy can be createdcreates more deliverable energy.. Depending on the surface area, sometimes less is more, this is one of those times.Again one is nothing without the other. You are correct, almost. I can make energy with speed, I can't make speed with energy

But I'm done with this one you are starting to take this one sideways,, too bad it was a good topic..

It is a great topic. It is too bad that you can't take a moment and actually learn something. You are not correct in your assumptions. Math does not lie, nor can it be made to distort facts. I didn't make this stuff up, it is fact, whether you choose to accept it is your choice. You are not supporting your argument, you are not answering any questions, and you are not showing me where I am wrong?

You say you can't make speed with energy,, you are forgetting one very important thing,, it's energy that created the speed.. The explosion in the cartridge is pure energy no speed to it at all it's pure energy. So we go back to basics,, for every action there is an equal and opposite reaction.. In this case I wouldn't call it equal but none the less the more energy applied at one end results in more energy delivered at the other..

But I'll make it easy on you before you have an aneurism,, Your Right..

Elk Cartridges

By Chuck Hawks


A generality is that around 1200 ft. lbs. of energy on target is necessary for humane elk kills. I think that bullet placement is much more important than kinetic energy, but this can serve as a rough guide to the maximum range at which a given load should be used.

You better get in touch with Chuck and tell him that velocity kills and energy is not a big factor.  It is velocity that creates the wound channel, not energy. See one of your statements above.- See more at: http://albertasportsman.com/alberta-guns-and-shooting/energy-and-what-it-does-to-game/msg25290/#new


I don't see any relevance in you questions about the exact amount of energy for the exact weight of the animal you are shooting so I will not bother commenting.

Wow!

The explosion is the case creates the speed. And yes, while it is energy, it is not the kinetic energy we are discussing.
You want to go back to basics? For every action, there is an equal and opposite reaction. This is correct. This means that the energy that bullet delivers, can not be greater that the energy that the butt of the rifle delivers to your shoulder, under recoil. You explain to me how that is enough energy to kill an animal, and I'll give you a gold star you can put on your fridge.

You can't make this stuff up! Now you're just getting silly, and obviously still can't read.
I did not know that simple mathmatics has now become a "radical opinion"? You still must think that the earth is flat.
To quote the king of all do nothing couch riders, Chuck Hawks, is pure comedy gold!
Around and generality? Really? Sounds a lot like a guess to me. Why would you take a guess at energy, when you have an exact velocity number to work with?
You don't see the relevance in my questions, because you would not have even half a clue as how to answer them, so it makes perfect sense that you wouldn't bother to comment.
Get back on the couch, and look out the window at the flat earth.

No you asked me to prove you wrong and I did,, you said you can't create speed with energy as I stated its energy that created the speed and again the more energy applied at one end results in more energy delivered to the other,, what part of this do you not understand.. If you want to get really into it,, all speed is is energy. The energy is trapped in the projectile causing it to speed across gravity..

Holy crap!
Did you even go to school? Now you don't even know what you're on about!
So me an eqaution for speed, that involves kinetic energy? You can't, because it doesn't exist.
You haven't proven a damn thing, except how ignorant you are.
It is the speed that creates the energy. Look it up. You must a speed variable in the eqaution to calculate kinetic energy. Again, there is no kinetic energy variable to calculate speed.
The only thing that will give me an aneurysm is your stupidity and stubbornness not to look at a couple of equations.
You fellas carry on in foo foo couch rider land. I'll stick to the math.
