How much kinetic energy to kill a deer.

How much kinetic energy does an arrow possess? An arrow strikes with force determined by its weight and the bow's draw length. The maximum force that an arrow can generate is called the "max draw weight" and can be as high as 200 pounds. Arrows will only travel a certain distance before falling to the ground due to gravity.The list that follows is intended to suggest the relative killing power of various hunting cartridges and loads at 100 yards when those cartridges are used appropriately. ( Cartridge, bullet weight in grains, muzzle velocity in feet per second - killing power score at 100 yards.) .223 Remington (60 grain at 3000 fps) - 6.3.Aiming between that 30- and 40-yard pin for a 35 yard shot is much more precise when pin gap is smaller. I mentioned earlier that a light arrow with a high kinetic energy won't have the energy retention that a heavier arrow would after impact. This is true, but what about a heavier arrow with a high kinetic energy? It's commonsense really.The case length of a 243 is 2.045", while the Creedmoor has a shorter case length of 1.92". Some might mix these two rounds up because their overall length is close to the same, and rim diameter is the same. The 6.5 Creedmoor round is 2.825" long with a rim diameter of .473". The 243 Winchester is 2.71" long with a rim diameter of .473".

Kinetic energy is physics ke=.5 x mass x velocity squared. For shooting we have to add in the acceleration due to gravity to convert from weight to mass and convert from grains to pounds so the formula becomes Ke= grains x velocity squared/ 2 x 7000 x 34.17 The 34.17 is relative to lat/long and elevation but that number is the accepted one …

Nov 1, 2019 · Nov 7, 2019. #9. Those "rules" are from a long time ago. What you need is enough speed to cause the bullet to expand properly and enough energy to push that bullet through to the vitals. You definitely don't need 1200 or deer. 9mm kills deer just fine with 350 ftlbs of energy.

The typical .45cal ball only has about 300lbs energy at 100yds but if put through the heart/lungs will kill a deer as dead as if it was 10 yards in front of the muzzle. If you use the manufacturers recommended max or near max powder charge and place your shot, all but the small size round balls will get it done to 100yds.If the average person can punch at a 15 mph and v is in meters per second this means a punch is moving ~6.7 mps. This gives that punch 45j. Now the average man in the USA weighs about 200 pounds and the average male arm makes up 5.7% of the body. This gives the arm 11.4 pounds which is ~5.2 kg. That would give a punch force of 116j.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.A 500 grain arrow moving at 260 fps has a kinetic energy of 75.04 ft-lbs and a momentum of .577 slugs*. A 700 grain arrow moving at 175 fps has a kinetic energy of 47.59 ft-lbs and a momentum of .544 slugs*. *The slug is a measurement of force defined as the mass that is accelerated by 1 ft/s 2 when a net force of one pound (lbf) is exerted on it.The "best" deer bullet for .243 Win rifles is a 100 grain bullet in a cartridge containing enough powder to propel that bullet/projectile roughly 2900-3000 feet per second (fps). At that bullet weight and projectile velocity, enough kinetic energy is available to make clean reliable kills out to 400 yards. But this isn't the entire story.

40 According to the folks at GoldTip, it takes about 40 foot-pounds of kinetic energy to get a complete pass-through shot on a whitetail deer. About 50 foot-pounds is required for an elk.

There are, however, three popular myths. Myth: Crossbows generate outlandish amounts of kinetic energy compared to compounds. Fact: Math is math-The average crossbow generates roughly 80 to 100 foot-pounds of kinetic energy. A crossbow developing 300 feet per second (fps) with a 420-grain arrow generates 86.78 foot-pounds of kinetic energy.

Max Speed: IBO arrow (5 grains/per pound of draw weight). Max Efficiency: arrow ~10-15% over IBO (5.5 grains/per pound of draw weight). Max Energy: arrow ~20% over IBO (6 grains/per pound of draw weight). Shoot three arrows and use the average of the three shots. Enter speed and arrow weight data into the calculator.Brain Injury 21 (7): 657-662, 2007. [1] Hydrostatic shock, also known as Hydro-shock, is the controversial concept that a penetrating projectile (such as a bullet) can produce a pressure wave that causes "remote neural damage", "subtle damage in neural tissues" and "rapid effects" in living targets. [2] [3] [4] It has also been suggested that ...Physics questions and answers. An air-track cart with mass m1=0.26kg and initial speed v0=0.90m/s collides with and sticks to a second cart that is at rest initially. If the mass of the second cart is m2=0.52kg, how much kinetic energy is lost as a result of the collision?Smaller calibers require great skill. When you increase the caliber size from .177 to .22, .25, .30, .357, .45 and upward, then the precision required for a humane kill decreases. There are some calibers that are very well suited for various types of game. The general rule in the airgun world has always been .177 for feathers and .22 for fur.The 223 Remington is an amazing cartridge that can accommodate bullets ranging from 35 grains all the way up to 77 grain bullets. In general, most big game hunting cartridges will have heavier bullets as these will pack on more kinetic energy and penetrate deeper. Typically, these bullets weigh 60 grains or higher.A 1 ms smack requires more acceleration to kill you than a 100 ms smack. Penetrating injuries to the head have a good chance of killing you. The army long used 58 ft-lbs as the energy of a projectile (bullet or fragment) needed to cause a casualty, but that just assumed a hit and not necessarily a hit to the head.

A 1 ms smack requires more acceleration to kill you than a 100 ms smack. Penetrating injuries to the head have a good chance of killing you. The army long used 58 ft-lbs as the energy of a projectile (bullet or fragment) needed to cause a casualty, but that just assumed a hit and not necessarily a hit to the head.bullittboy Discussion starter. 47 posts · Joined 2003. #1 · Oct 26, 2004 (Edited) I'm shooting a 332 grain arrow at 260 fps.. which gives me 50 ft-lbs of kinetic …Killing Power: Bullets and Arrows. The concept of impact energy and "killing power" are pervasive throughout the literature and come up in just about every discussion on cartridges. The size of the game animal also factors heavily in cartridge choice. People routinely shoot and kill deer (for instance) with a 400 grain arrow and a "muzzle ...The amount of kinetic energy required to cause a fatal wound will vary depending on the size of the deer, the location of the shot, and the type of arrow being used. However, as a general rule of thumb, a crossbow with an FPS of at least 300 is …The Spot You Need To Hit. With a quality bullet or slug, you can kill a broadside deer in its tracks by shooting through the near-side shoulder and into (or through) the off-side shoulder. And if you have the skills, gear and time to be extra precise in your shot placement, hit a bit high in the shoulder.Kinetic energy equals velocity squared, multiplied by mass, divided by 450,240. The sum equals the kinetic energy — a.k.a. KE in foot pounds — of an object in motion. ... Just as you can cleanly kill deer with a .22 Hornet, you can also kill elk with wide-cutting mechanicals and light arrows — if everything proceeds according to script ...

To calculate the kinetic energy, first convert km/h to meters per second: 40km/h = 11.11 m/s. Using the first kinetic energy equation above, replace the values for m and v and get KE = 2200 · (11.11) 2 / 2 = 135775.3 Joules or 135.7753 kiloJoules. Example 2: A ball which weighs 500 grams has a kinetic energy of 500 J.

Depending on the bow you use and the arrows you use, your kinetic energy could range from 30 foot pounds at 30 yards to almost 125 foot pounds at 30 yards. These numbers are dependent on the FPS of the crossbow. The higher the FPS, the higher the kinetic energy will be. As the arrow moves through space, the kinetic energy drops.For example, having 1,500 ft-lbs of energy to kill a bull elk is a decent barometer, but elk have also been killed with far less energy when excellent shot placement and good bullet construction are in play. ... If …Science. Physics. Physics questions and answers. One car has twice the mass of a second car, but only half as much kinetic energy. When both cars increase their speed by 8 m/s they then have the same kinetic energy.What is the original speed of the lighter of the two cars?How many ft lbs of energy does it take to kill? A commonly accepted threshold for the minimum amount of kinetic energy needed to kill an elk is 1500 ft-lbs. For whitetail deer, the minimum amount of kinetic energy is 1000 ft-lbs. We’ve all probably heard stories of hunters taking elk with a . 243 Win.Lot of people say 1500 ft/lbs minimum at maximum range. Any modern rifle in 30 caliber will do that out to 300 yards. Lots of people comment on 7 rem mag as being too fast. My friends that elk hunt in Wyoming, Colorado, and Montana use the same rifle for Mule Deer and Elk— 284 Winchester, 300 Win Mag, 338 Win Mag.A recent example that demonstrates this clearly is this video by DIY Sportsman. The data given spans arrow masses from 379.4 grains to 1163.5 grains. That is an increase in arrow mass of 207%—a tripling of arrow mass. The kinetic energy of the arrow leaving the bow increased from 73.3-77.9 ft·lb., a mere 6% increase.The 1,000 ft.-lbs. standard is not guaranteed to flatten a deer, but provided other factors (like adequate bullet construction) are present, this level of kinetic energy is required to get the bullet into the vitals. And, ultimately, adequate penetration into life-essential organs is the only way to kill game. Whelen's rule was for deer-size game.Anything comparable to .243 or above should have sufficient power to take any size hog at any reasonable distance with good shot placement. In Hawaii, the rule is anything greater than 1,200 ft/lbs ME, so .223's are legal. I personally use a 7mm rem mag on hogs, but my cousin uses a 30-30 and my coworker uses a .270.

The list that follows is intended to suggest the relative killing power of various hunting cartridges and loads at 100 yards when those cartridges are used appropriately. ( Cartridge, bullet weight in grains, muzzle velocity in feet per second - killing power score at 100 yards.) .223 Remington (60 grain at 3000 fps) - 6.3.

Here are a couple home remedies you might want to try to keep deer away from your lawn or garden. Expert Advice On Improving Your Home Videos Latest View All Guides Latest View All...

Here are the equations: Momentum = Mass x Velocity. Kinetic Energy = (1/2)Mass x Velocity^2. Notice that you can't have one without the other. Each is defined in terms of the same variables - Mass and Velocity. When the author of your book said that energy is not a factor in a kill, something got lost in translation.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 ...My pronghorn/mule deer arrow is an Easton HyperSpeed Pro branded with a .400 spine and a gpi of 7.4. Total arrow weight is 387.4 grains. My fps (feet-per-second) with this shaft is 296. When you crunch the numbers, I get a kinetic energy rating of 75.28 foot-pounds. I blow through pronghorn, mule deer and even elk with this arrow.Dec 1, 2012 · To score an instant kill with the usual deer rifle, exact bullet placement is required in a vulnerable area. The required degree of bullet placement will vary almost directly in proportion to the size and life tenacity of the animal, but will be somewhat inversely proportional to the striking energy and momentum of the bullet provided that expansion and penetration are uniformly balanced. A recent example that demonstrates this clearly is this video by DIY Sportsman. The data given spans arrow masses from 379.4 grains to 1163.5 grains. That is an increase in arrow mass of 207%—a tripling of arrow mass. The kinetic energy of the arrow leaving the bow increased from 73.3-77.9 ft·lb., a mere 6% increase.Max Speed: IBO arrow (5 grains/per pound of draw weight). Max Efficiency: arrow ~10-15% over IBO (5.5 grains/per pound of draw weight). Max Energy: arrow ~20% over IBO (6 grains/per pound of draw weight). Shoot three arrows and use the average of the three shots. Enter speed and arrow weight data into the calculator.Anything comparable to .243 or above should have sufficient power to take any size hog at any reasonable distance with good shot placement. In Hawaii, the rule is anything greater than 1,200 ft/lbs ME, so .223's are legal. I personally use a 7mm rem mag on hogs, but my cousin uses a 30-30 and my coworker uses a .270.In an experimental technique for treating deep tumors, unstable positively charged pions (π + , elementary particles with a mass of 2.25×10−28kg) penetrate the flesh and disintegrate at the tumor site, releasing energy to kill cancer cells.If pions with a kinetic energy of 12 keV are required and if a velocity selector with an electric field strength of 1.5×10 3 V/m is used, what must be ...3,567. Location. Falls Church, VA. Sep 12, 2010. #3. Although I agree with bigngreen that 1000lbs of energy and a well placed shot will take elk, the conventional wisdom says you need 1500 pounds of energy. So I ran your load in exbal and found that you have 1500lbs of energy at 500 yards and 1000lbs at 800.Yes, the .223 Remington is clearly a more powerful cartridge than the .22 Hornet. Similar to the 10mm vs .45 ACP debate, the .223 Remington has more energy remaining at 200 yards than many .22 Hornet loads have at the muzzle. However, the body of evidence also indicates that both cartridges are very effective on predators, small game, and varmints.#1 · Jan 29, 2011. I just wanna know peoples opinions on recommended kinetic energy for elk. Ive got some shoulder damage and cant pull 70lb bows anymore. Any ideas? Like. …A 2.0-kg object moving with a velocity of 5.0 m/s in the positive x direction strikes and sticks to a 3.0- kg object moving with a speed of 2.0 m/s in the same direction. What is the final velocity of these two objects? How much kinetic energy is lost in this collision? 2. An 80-g particle moving with an initial speed of 50 m/s in the positive x.
