How much kinetic energy to kill a deer.

velocity x velocity x total arrow weight (in grains) divided by 450,240. How much do your arrows weigh in grains. How fast (in feet per second) are your arrows. to calculate your KE (kinetic Energy) Your KE = How much KE do you really need? If you're hunting deer, you don't need much at all. As long as you make a good shot, that is.At 50 yards downrange, a typical .357 Mag. bullet is traveling about 1,100 feet per second. That is 750 mph. Despite its power, recoil is more manageable with the .357 Mag. than with the .44 Mag., as the latter requires a bit of masochism if you are to enjoy even a half-hour shooting session.The 308 Win's .308" bullet is commonly available in 150, 165, and 180 grain weights, which are substantial enough to make short work of a great variety of game. In experienced hands it can hit a 1,000 yard target. Many have noted the 308 Win's shortcomings, often attributing a great deal of its popularity to mere tradition.Some would call any problems death from infection or starvation cruel. Others may even call it or even a clean kill justice. It all depends on perception & truths which we won't get into. I'd personally want a custom .257, RAW .30 or .357 A .22-250 would be great & be sure to kill anything I mean to out to 400 yards with a good range finder.

Best Answer. It takes only 80 joules of kinetic energy in a bullet to kill a normal human being if it hits any of the unprotected vital portion of our body. Wiki User.

The .264 caliber 130-grain bullet has a G7 ballistic coefficient of .263, while the 200-grain .308 version has a G7 ballistic coefficient of .304. With Federal’s Gold Medal primers and specially formulated propellant, Terminal Ascent bullets have all the right components for accuracy. Field-Testing Ballistic Theory.Measuring kinetic energy is how most bowhunters determine an arrow's killing potential. The number is arrived at by multiplying speed squared by arrow mass and dividing the resulting figure by 250,240. ... you can't beat a whitetail to the jump. A fast arrow travels around 300 fps, but sound travels at about 1,225 fps. And whitetail's reaction ...

Normally a conical is fired at velocities between 1,200 and 1,600 feet per second (fps). A 370-grain .50-caliber conical with a 100-grain charge will have a velocity of about 1,450 fps. The muzzle energy of such a load is 1,727 ft./lbs., but at 100 yards, only 825 ft./lbs. My .58-caliber 260-grain round ball with a 100-grain blackpowder charge ...Kinetic energy is the only type of energy capable of killing a deer. The amount of energy required to kill a deer depends on a multitude of factors including the size of the deer, type of ammunition, and distance of the shot.

Even then, there's no guarantee that it will kill a deer because the skull can deflect the round. There's simply insufficient bullet weight, muzzle energy, or knock-down power to kill a deer.

An arrow or bolt’s kinetic energy is greatest immediately after being discharged from a crossbow’s string. This energy also dissipates rather quickly with each yard of arrow flight, meaning that a bolt or arrow strikes a target with much more kinetic energy at 20 yards than it does at 50 yards.

The .22-250 Remington will throw a 60-grain pill at least 3,600 fps. Sighted dead-on at 200-yards, it will drop just 5.4 inches at 300-yards and still be packing 816 ft. lbs. That's 300 ft. lbs. MORE than the 30-30 Winchester with a 150-grain flat nose. A .22 caliber bullet with enough energy down range is perfectly capable of killing a deer ...

Greater speed increases kinetic energy, which can improve penetration and lead to improved recovery rates on game. That said, a well-placed arrow from a 300-fps bow will kill a critter just as ...The average deer weighs between 150 and 300 pounds so it takes a lot of force to kill one. Depending on the size of the deer it takes between 1.5 and 3.0 foot-pounds of energy to kill a deer. This means that it takes between 12 and 36 inches of penetration to kill a deer. How many Joules of energy are required to kill a deer?One foot pound equals about 1.36 joule, 0.32 calorie, or 0.0013 Btu. Not enough heat to significantly raise the emperature. We are not talking about 1 ft lb of energy, we are talking about 4800 ftbs. If most of that energy was transfered into thermal energy, it would blister your finger to touch the target or bullet.Mar 22, 2024. #1. I'd like to see a discussion on what is considered 'Enough' energy to effectively kill an Elk, Deer, Antelope...critter in general. I've seen folks suggest that anything over 1100ft/lbs all the way to a minimum of 1500. While looking at some Pistol data, I found that a .45ACP 230gn bullet has 369 ft/lbs of energy at the muzzle ...One foot pound equals about 1.36 joule, 0.32 calorie, or 0.0013 Btu. Not enough heat to significantly raise the emperature. We are not talking about 1 ft lb of energy, we are talking about 4800 ftbs. If most of that energy was transfered into thermal energy, it would blister your finger to touch the target or bullet.To calculate Kinetic Energy we can use the following basic formula. KE = .5Mass x Velocity². For bowhunters, we can take the total weight in grains of our arrow as Mass. Velocity can be speed of the arrow in feet per second. The final equation to calculate your arrow's KE will be. KE = (Mass)x (Velocity x Velocity)/450,800.Question: (13%) Problem 6: During an ice show, a 52.5-kg skater leaps into the air and is caught by an initially stationary 87.5 kg skater 5 % Part(a) What is their final speed, în meters per second, assuming negligible friction and that the 52.5 kg skater's initial horizontal speed is 4.25 m/s? v 1.59 Correct! 50% Part (b) How much kinetic energy is lost, in joules?

In general, an arrow loses five feet of its kinetic energy per 10 yards after impact. So for a 40 lb bow firing out a 300 grain arrow at 230 fps for 50 yards shot from this same bow will only have 28 feet-lbs left upon impact at impact. As such, less kinetic energy is required than many hunters believe to kill a deer.The kinetic energy formula works in classical physics, but it starts to deviate from true energy when the velocity approaches the speed of light (c). How to Calculate Kinetic Energy. The key to solving kinetic energy problems is to remember that 1 joule equals 1 kg⋅m 2 ⋅s −2. Speed is the magnitude of velocity, so you can use it in the ...Kintetic Energy Formula. The formula for K.E. as measured in ft./ lbs. is: Mass x Velocity-squared divided by 450,240, with Mass the total arrow weight and velocity is the arrow speed. So let's say you have an arrow that weighs 400 grains that flies at a speed of 290 feet per second. Your equation would look like this: 290 x 290 x 400 / ...Speed is a component in the equation, but mass affects MO and penetration much much more over speed. You will kill a deer with an arrow flying 50fps if it weighs 700, 800, 1000 grains, I don't know that number. I would be willing to bet you could get a PT at 10 yards. ... This is because kinetic energy determines the potency of the arrow being ...The .243 Winchester fires a 95 gr. spitzer bullet at 3100 fps in one popular hunting load, producing 2021 ft. lbs. of muzzle energy in the process. Many thousands of hunters arm themselves with .243 rifles and kill an inordinate number of deer and antelope every year. (Thereby demonstrating its effectiveness for such use.The minimum kinetic energy needed to bow hunt whitetail deer is 25 ft-lbs. This is the absolute minimum. Compound bows with a draw weight of 40 lb generally put out a 240-grain arrow with 30 ft-lbs of kinetic energy. To increase kinetic energy you can increase draw weight or arrow weight.

Physics questions and answers. Two figure skaters, one weighing 625 N and the other 725 N, push off against each other on frictionless ice. (a) If the heavier skater travels at 1.50 m/s, how fast will the lighter one travel? (b) How much kinetic energy is "created" during the skaters' maneuver, and where does this energy come from?One of its most popular factory loads features the 115-grain Nosler Ballistic Tip bullet with a muzzle velocity of 3,400 fps, which generates 2,952 ft.-lbs. of kinetic energy (K.E.)—comparable muzzle energy to the .30-06 and .35 Whelen. The .257 Weatherby Magnum shares the same cartridge case as both the .270 and 7mm Weatherby Magnums.

The initial K.E. generated at the shot is 71.53 ft./lbs. (To determine how much initial kinetic energy your own bow-and-arrow set-up has at the shot, the formula is which is arrow weight (mass) x velocity squared, divided by 450,240. Most experienced bear hunters I know believe that for averaged-sized bears taken at reasonable ranges — under ...Nebraska deer regs. requires 800 ft/lb at 100yd for rifle and 400 ft/lb at 50 yd for handguns. Nothing is said about energy at impact. Ranges where I am at can be really long. I believe they are minimum energies at points of impact (.22 cal) and an excellent guide/requirement.The problem aims to answer three questions: a.
