When chest shooting heavy game, a heavy but stout controlled expanding projectile driven as fast as the shooter can manage produces the fastest possible killing. As O'Rourke said, use enough gun. Use enough gun. The .338 Win Mag and controlled expanding 225gr Nosler Partition can be put to great work on bear. Lots of opinions. Even the lawmakers in some states have one, as they put regulations around minimum draw weights for hunting - usually 40 pounds. And while it's an important factor in the equation, draw weight is not the only consideration a hunter needs to take into account to ethically hunt whitetails. There's draw length, arrow weight ...Rifle rounds on the other hand have more kill (kinetic) power. This is possible even at long ranges if you have the proper shot placement. Reasons attributed to the more deadly energy for 5.56x45mm NATO cartridge include; Gas Pressure. A 5.56 mm rifle round has higher pressure gas which results from the imploding and expanding powder. This ...Medium-sized game like deer, pronghorn, and sheep require an arrow with a kinetic energy range of 25-41 ft./lbs. When hunting large-sized game such as elk, black bear, and wild boar, it is recommended to have ammunition with a kinetic energy range of 42-65 ft./lbs.

Something else enlightening is retained energy downrange. At 150 yards the 95-grain .243 bullet is hauling 522 f-p more energy than the much heavier 30-30 slug. At 400 yards the puny, ineffective 243 is still packing more punch (1,077 f-p) than the 30-30 at 150-yards, what many consider "dead deer" distance for the famous 30-30.

The unofficial rule regarding minimum KE to push an arrow through a deer is about 40 foot-pounds. Lower-poundage bows are slower than higher-poundage models. So, let’s say the bow is pushing a 350-grain arrow at 265 feet per second. That setup is delivering roughly 54 foot-pounds of KE and .411 slugs of momentum.

Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass. The kind of motion may be translation (or motion along a path from one place to another), rotation about an axis, vibration, or any combination of motions. Translational kinetic energy of a body is equal to one-half the product ...A kinetic bombardment or a kinetic orbital strike is the hypothetical act of attacking a planetary surface with an inert kinetic projectile from orbit (orbital bombardment), where the destructive power comes from the kinetic energy of the projectile impacting at very high speeds. The concept originated during the Cold War.. Typical depictions of the tactic are of a satellite containing a ...In North Carolina, a 35 pound pull compound is legal for hunting. Recurves have to be 45 pounds. Compounds used to be 45# also but this was changed by the NCWRC after the NC Bowhunters Assn. showed them that modern compounds at 35# had as much kinetic energy as 45# recurves.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.

MO/KS state line. I think MO did away with their old minimum of 30# DW but if you calculate with one of the online calcs...a bow with a 325 IBO and a 324 grain arrow with a draw weight of 35# is only about 41 ft lbs of KE which is widely considered adequate to kill a whitetail deer.

“What is thought to be the minimum foot-pounds of energy required to dispatch anything from whitetail deer to moose humanely and ethically?” The most …Oct 27, 2012 · Accuracy trumps kinetic energy and momentum of the arrow. You could kill any whitetail deer with a 45 lb bow shooting a 300 grain arrow with a field point. But if you don't hit the vitals it wouldn't help shooting a 500 grain arrow with a 80 lb bow and a 3" head. You might end up with a dead deer but good luck finding him. Nov 9, 2005 · just wondering with all this speed speed speed what do you need to have to take a deer at say 25 yards how much kinetic energy is enough to kill swiftly. reading the ttb1 tim talks about howard hill with a 40 pound bow shooting a 450 grain arrow in the 140s the kinetic energy is about 20 foot pounds . so is that enough. i know all the spped equals better accuarcy but at 25 or 30 yards that ... 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.Oct 27, 2012 · Accuracy trumps kinetic energy and momentum of the arrow. You could kill any whitetail deer with a 45 lb bow shooting a 300 grain arrow with a field point. But if you don't hit the vitals it wouldn't help shooting a 500 grain arrow with a 80 lb bow and a 3" head. You might end up with a dead deer but good luck finding him. In order to be successful in taking down a deer you need to have a bow that is properly sized for the game you are hunting. As a general rule you will need at least 40 pounds of draw weight to kill a deer. This means that the bow must be able to pull back the arrow with enough force to penetrate the animal’s hide and reach the vital organs.

How much does it take for a pass through on a averageI've always suggested using Energy (lbs) thats (4 x the animals weight). Example a 200 pound deer needs 800ft.lbs. energy. deer: 700-1400lbs. "Energy". Elk: 1400-2000lbs. of course there is lots of varibles but this is a good rule of thumb.With that in mind, most hunters would agree that the max effective range of a .243 for deer hunting will be anywhere from 200 to 400 yards. Other external factors will also come into play, from the wind, weather, and shooting position. You also have to consider the skill level of the shooter, so really the maximum effective range will vary from ... As long as you make a good shot, that is. According to Easton, a 400 grain arrow traveling at the glacial speed of 170 feet-per-second has sufficient energy to harvest a mature deer. Heck, many kids bows can easily shoot such a light arrow faster than 170 fps, and I’ve seen such rigs do pass-throughs on deer! The rule of thumb for the minimum amount of kinetic energy needed to kill a mature elk is 1500 ft-lbs. The size of the "kill zone" on a bull elk ranges from 16 to 18 inches. Essentially then, any caliber and bullet capable of producing the required kinetic energy with a minimum drop of around 12 inches at specific distances should be enough ...Because projectiles launched with compressed air generate substantially less terminal kinetic energy than projectiles launched with gunpowder. ... any airgun – is all about precise shot placement. Thus, the limits of the practical range for killing big game like deer and hogs humanely with the most powerful big-bore airguns, is 60-80 yards ...

In order to kill a deer with a single FPE, it would need to be a very large deer. The average whitetail deer weighs between 120 and 200 pounds, so it would take at least 1,200 ft-lbs of energy to kill one. That’s equivalent to about 12 FPE. So, while it is possible to kill a deer with a single FPE projectile, it’s not likely.Kinetic Energy & Momentum Calculator. Find out the kinetic energy of your arrow or bolt using the following simple calculator. Your kinetic energy is [ field2 * (field4 * field4) / 450240 ] foot pounds, and your momentum is [ field4 * field2 / 225400 ] slug FPS. FormCraft - WordPress form builder.

In North Carolina, a 35 pound pull compound is legal for hunting. Recurves have to be 45 pounds. Compounds used to be 45# also but this was changed by the NCWRC after the NC Bowhunters Assn. showed them that modern compounds at 35# had as much kinetic energy as 45# recurves.Kinetic energy is energy in motion. A 150-grain bullet standing still has potential energy. Dropped, it has a bit of kinetic energy, and you'll feel this should it land on your naked toe. Push this same bullet with about 50 grains of Hodgdon 4350 powder behind it, and you won't want to feel it on your toe or anyplace else. It will be ...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.In both cases the Berger bullet totally destroyed the vital area (heart-lung) area. The damage I detected at this range convinces me that Berger is right, at 1800 yards the same bullet hitting the vital are would definitely work on deer size animals. Don't get hung up on Kinetic Energy.A 35-45 psi overpressure may cause 1% fatalities, and 55 to 65 psi overpressure may cause 99% fatalities. (Glasstone and Dolan, 1977; TM 5-1300, 1990) BTW, damage in Humans mainly occurs at the interface of areas of different density eg lungs and eardrums. It is essentially a spallation effect like Newton's Cradle in tissue.Energy gives us an idea of how much power there is to initiate things like bullet expansion and penetration, but does not guarantee that they will occur. It is generally recommended that a small bore (.24-.32 caliber) rifle bullet suitable for medium size (CXP2 class) game be carrying about 800 ft. lbs. of kinetic energy when it hits.Understand How Kinetic Energy Works in the Field. When it comes to actually hunting for game, the required kinetic energy is much less than most people anticipate. For example, if you use your crossbow to hunt for deer, you only need between 25 and 40 foot pounds to take one down. The larger number is recommended, but the lesser number will ...Oct 6, 2016 ... The larger number is recommended, but the lesser number will work on a smaller deer. To hunt for large game like a grizzly bear, you need ...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.The muzzleloader has 2,680 ft.-lb. of energy at the muzzle and only 1,180 ft.-lb. at 200 yards. At 243 yards, the bullet falls below 1,000 ft.-lb. of energy—the widely accepted minimum needed to ethically kill whitetail deer. With even a 10 mph wind, the 250-gr. Barnes will drift 10.91 inches at 200 yards.

Location. MN. Mar 23, 2024. #33. Hit that North Dakota Buck with a nearly 2,288,000 grain slug ( 1997 GMC K-2500 Suburban ), that was traveling around 110FPS (75mph). A guy would think 61,468 ft lbs of energy would a stopped him, nope, not even a decent blood trail.

Feb 20, 2024 · For deer hunting, it is recommended to have a ballistic energy of at least 1,000 foot-pounds to ensure a clean and ethical kill. 1. What is ballistic energy? Ballistic energy is the measure of a bullet’s ability to penetrate its target. 2. If the car brakes over a distance of 50 m before coming to rest, what is the force of friction. Here's the best way to solve it. (a) (b) The energy gets dissipat …. Pkg 0.21 7. A car of 1200 kg is travelling at 20 m/s when it slams on the brakes. a.In terms of power, the airgun should generate minimum kinetic energy of 10 foot-pounds to be considered a legitimate hunting weapon. This minimum requirement is adequate for taking animals like rodents, most birds, and small game like squirrels and cottontail rabbits. Larger game requires more energy.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.A chronograph can be used to measure speed or can be obtained from the manufacturer. Once these figures are known, multi- ply velocity X velocity X total arrow weight in grains, and then divide that figure by 450,340 to obtain kinetic energy in foot-pounds. The weight of crossbow arrows is designated in grains.11326 posts · Joined 2010. #9 · Oct 5, 2021. It’ll kill a whitetail at whatever range you can hit with it, based on trajectory. Energy-wise you’d be good to at least 300 but you’ll be aiming a couple of feet high.The Swiss's kinetic energy is 1/2 times .05 kilograms times two meters per second squared, which is .1 Joules, or half the kinetic energy of the cheddar. So we can see that at the same speed, the cheddar has more kinetic energy because it has more mass. But when the Swiss has a speed of four meters per second and the cheddar still has a speed ...This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer. Question: A sledder has 500 J of potential energy and 250 J of kinetic energy at one point on a steep hill. How much kinetic energy will the sledder have at the bottom of the hill?Beretta and FN Herstal both developed less lethal shotguns, the LTLX-7000 and the FN 303, but neither brought the devices to the civilian market. Eric Bratten, who helped found the less lethal weapons company Mission Less Lethal and has worked at others, said the gunmakers were afraid of undermining their existing business.It's something one would use to stand against something like a grizzly. To get the energy of 70 ft. lb. it needs to travel with at least 250 fps (feet per second). We need to find a bow which can accelerate a 500 gr arrow to 250 fps. A Bear Archery Grizzly with 48 pounds manages to accelerate a 503 gr arrow to 140 fps.Question: The diagram below illustrates the collision of two balls over a smooth surface. The first ball (blue) has an initial velocity of 4.25 m/s and a mass of 5.0 kg. The second ball (red) has an initial velocity of 6 m/s with an unknown mass. After the collision, the second ball (red) has a velocity of 3.5 m/s in the direction shown below.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.

There are several factors that go into the arrow speed equation. When shooting a compound bow, all things being equal, they are: Draw weight: The more draw weight you pull, the faster the arrow will fly. The rule of thumb is that for every 10 lbs. of draw weight your bow is reduced, raw arrow speed is reduced 15-20 fps.There is no easy answer when it comes to the amount of draw weight needed to kill a deer. It depends on a number of factors, including the type of bow, the type of arrow, the deer’s size and weight, and the hunter’s skill level.Find the latest Kinetics Medical Fund (KRXAX) stock quote, history, news and other vital information to help you with your stock trading and investing.May 7, 2009 ... Energy needed for a clean kill for some of the following animals and not all classified too many to list, just a few samples: 1) Deer & Black ...Instagram:https://instagram. listen to gene autry peter cottontail To hunt a deer perfectly, one needs to ensure enough deep arrow penetration for a quick and humane kill. But how much arrow is needed to kill a deer depends on many factors. Generally, 40-60 pounds of kinetic energy and 12-14 inches of arrow penetration are needed to kill a deer in an effective way. candy montgomery crime scene photos 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. david venable net worth Michelle's Hoyt Trykon Sport, the one she used to kill the hog, is set at 40 pounds and has a draw length of just 23 inches. It launches a 320-grain carbon arrow/broadhead at 198 fps and produces about 28 pounds of kinetic energy. That's pretty light, but it's obviously enough to bring down a big hog and a whitetail. When it comes to bows, energy is stored in the limbs and cams when the bow is drawn, then transferred to the arrow shaft at the shot in the form of kinetic energy, or K.E. My 28½-inch Easton 4mm FMJ shaft tipped with a 100-grain broadhead weighs in at 380 grains – a medium-weight shaft that will produce enough K.E. and momentum when shot ... kenmore dryer model 110 capacity It carries 1,000 ft-lbs of energy out to 800 yards. The Shooter’s Responsibility. Another huge factor in successful long-range hunting is the hunter’s ability to hit the animal’s kill zone every single time. The dirty little secret that many who are promoting long-range hunting keep hidden is how difficult that can be under hunting ... ed sheeran las vegas ticketmaster MO/KS state line. I think MO did away with their old minimum of 30# DW but if you calculate with one of the online calcs...a bow with a 325 IBO and a 324 grain arrow with a draw weight of 35# is only about 41 ft lbs of KE which is widely considered adequate to kill a whitetail deer. how to install mare ffxiv Most recommend at least 40 ft-lbs for a pass though on deer. This set-up is around 28 ft-lbs. If your son understands the importance of a well placed short range shot on a broad side or quartering away deer, I would not hesitate in letting him use it. If you had asked this question several years ago, I doubt there would be very much discussion. cemu vs yuzu botw Calgary, Alberta, Canada. Jul 19, 2001. #1. Anyone have any thoughts on the amount of terminal energy required to cleanly kill game? I looked in a hunter-ed book and it lists the following as suggested minimums. Deer, Antelope, Sheep 900 ft/lb. Elk, Small Bear 1500 ft/lb.In fact, the average crossbow generates about 80 to 100 FP KE, or foot-pounds of kinetic energy. If you see a crossbow with a 300 FPS using a 400-grain arrow, then you’ll generate about 76 FP KE. If you are hunting large game, then your arrow has to be traveling faster. However, it’s really the FPS at the time of impact that matters. noritake china pink flowers 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. potato parade ideas A company spokesman said: An old rule of thumb is that it takes 1,000 ft-lbs of energy to kill a deer. The 20 gauge has plenty of energy. For example, the Winchester Supreme 2¾” 20-gauge Partition Gold load uses a 260-grain bullet with a muzzle velocity of 1,900 fps and a muzzle energy of 2084 ft lbs.The critical factor to consider is the kinetic energy (foot-pounds) your bullet will strike the coyote with upon impact. For simplicity, I use the often suggested minimum of 10 ft/lb per pound to create a lethal hit on a coyote. In the United States, the average weight of a coyote is 30lbs. At 10 ft/lb per pound, that means you should use a ... baylen levine tour what to expect A knock on mechanical heads has always been penetration and a loss of kinetic energy upon impact. Bowhunters get worried about the shoulder. ... speed and know the kinetic energy your bow/arrow combo delivers, you can kill any animal in North America with a mechanical head. When you shoot a SEVR, you get extreme aerodynamics and a swept-back ...The Homing Overlay Experiment used a metal fan that was rolled up during launch and expanded during flight. The metal has five times as much destructive power as an explosive warhead of the same weight. A kinetic energy weapon (also known as kinetic weapon, kinetic energy warhead, kinetic warhead, kinetic projectile, kinetic kill vehicle) is a … katie maskell A coffee filter of mass 1.2 grams dropped from a height of 4 m reaches the ground with a speed of 0.8 m/s.
