Home Forums Hunting & Shooting Hunting Rifles Speed vs Energy?

EVERY bullet shot at game has a specific mass at the time of impact. And a specific velocity, specific momentum and specific energy. It isn't the speed that kills, it is the momentum or energy (take your pick - they are inextricably related) transferred to the target that kills by disrupting vital function. If speed alone killed, we would all be dead already.

One reason we are not dead is the 100 trillion neutrinos passing through our bodies at near light speed each second have such low momentum/energy levels (approximately .00012 ft-lbs each).

The other reason is that so few ever interact with your molecular structure, meaning they fail to transfer any momentum or energy to your body. If all of the 100 trillion neutrinos interacted with your body, you would be destroyed by about 12,000,000,000 ft-lbs of energy every second.

With respect, and not meaning to pick on you, if all your bucks were shot with the one calibre, using one of two bullets, all at more or less the same velocity, that may give you a data set which is perhaps deep (if you've shot enough bucks), but very narrow. If you haven't tested, for example, a range of velocities, how could you really say that velocity is a factor?

the small frequency of collisions is seen as genetic mutation. mutation rates are higher in high radiation areas. deserts etc.

as said momentum is the first derivative of energy, it is not energy itself, it has the same relationship as torque does to horsepower, torque gets you started and hp does the acceleration (a second order)

Not really the energy or the momentum, but the work. Specifically the damage done to vital organs. Energy alone won't do it, nor will momentum alone. For example, the momentum of the rifle in recoil is actually greater than that of the bullet, but the buttplate doesn't kill you. Concentrate that momentum in a smaller cross-sectional area, and have it delivered by a projectile which has edges to tear tissue rather than push it out of the way, and that will do the business.

According to STICK yes it will!!! Because apparently energy is a meaningless number so all bullets have ZERO energy. Energy is something Einstein made up that doesn't really exist. Even if it did exist once you break the 800 mph sound barrier it would than turn into light speed.

When you contradict yourself you can expect that it will be brought to peoples attention.




rest assured post mortem forensic specialists around the globe, don't abide by your CF definitions of trauma.

There are lots of neutrino research projects in the Alaska.

Rest Assured there isn't a Dr in the world that can cure your stupidity. But by all means please carry on.

a large part of the difficulty in this discussion is the intermixing of scalars and vectors.

scalars have magnitude, vectors have magnitude and direction

May the Force be with you

i have shot many bucks some real giants i have used different cartridges too some cartridges work as well like 264 Win.Mags and 270 Weatherby mags and i am sure some others are fine too. the recoil of these 3 cartridges i listed is low and all 3 do get the job done well at farther distances .believe me or not i don`t really care i know what works well easy,and at 66 years of age and plenty bench competition i do understand ballistics and done plenty reloading for over 40 years . but go ahead and use what , do what you want that`s your choice period !

I've been far more impressed by speed than any other factor

CB shorts kill pigs better than LR. How can that be?

Killed a big ol' boar once with a load of #3 neutrinos...DRT.

French fried velocity is one of my favorites. Big assed chunks of soft lead seasoned with bees wax is the other.

SPLAT.

In physics, work is a measure of energy transferred when an object (think flesh and bone) is moved.

As I said, "... it is the momentum or energy (take your pick - they are inextricably related) transferred to the target that kills by disrupting vital function."

I don't think they are talking about that kind of speed

I have shot deer with small and fast bullets, big and slow and big and fast bullets. They all kill the deer. The big fast ones do it before they run.

Neutrinos interact only through the weak force. They are non-ionizing, unlike alpha and beta particles and gamma rays (photons) that cause mutations.

My point was that, because they don't interact with the molecules in your body, there is no energy transfer, no work performed, no destruction of vital function - in spite of their near light-speed velocity.

As to momentum or energy, my point is that if you know one and you know the mass of the object (bullet), the other is a specific, knowable number that can be derived from the givens. Some people prefer to use momentum, others energy. Both are conserved entities. Once you specify the mass, I don't give a crap which people use.

Of course not. Anything with 0 ft lbs of energy either has no impact velocity or has no mass. The same reasons why your neutrinos are not the proper tool for the job.

What I do know is that when a proper tool for the job is used, energy really doesn’t mean much. For example, if we take deer as evidence:


I’m rather certain that if he’d shot the deer with a tiny little 100gr TTSX out, say, a .257 Roy instead of using the 300gr bullet in a .416 BEE, that smaller bullet with way less than half the energy wouldn’t have been less lethal. In fact, there is a good chance it would have been more effective. If energy mattered much, this could not be true.

yes, I was making a poke about all the parodies around 2000 about making neutron bombs and making neutrino bombs to neutralize them, guess no body remembers. sorry

I rorr on froor and raff too much. You crazy GI's!

I do know one thing, deer sized critters, speed really impresses them...
