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.Physics. Physics questions and answers. A 3 kg toy car sits at the highest point of a 13 m high hill. The car is gently pushed forward until it begins to roll down the slope. Assuming the car coasts freely, without any friction or air resistance, how much kinetic energy (KE) and potential energy (PE) will it have at each of the indicated points ...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 ...

Feb 21, 2024 · 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. In order to kill a deer with a crossbow you need to deliver a minimum of 1000 foot-pounds of kinetic energy into the animal. This can be accomplished with a well-tuned crossbow shooting arrows that weigh at least 400 grains at a minimum of 250 feet per second.If an object is moving, it has kinetic energy. In fact, the faster an object is moving, the more kinetic energy it has. Muzzle Energy Calculation. You can calculate kinetic energy using the classic formula you memorized in Physics class. Here it is for those of us who have long since forgotten: KE = 0.5 • m • v 2. where m = mass of object

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.By Nahid August 5, 2023. The effective range of the 6.5 creedmoor for deer is approximately 800 to 1,000 yards.

This versatile round performs exceptionally well in terms of ballistics and energy ...

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 ...The killing power of an arrow is measured in Kinetic Energy. Think of it as the force behind the arrow that drives it. More force equals deeper penetration. ... the minimum KE required for deer-sized game is 25 pounds. Most modern bows with at least a 30- to 40-pound draw weight and a 24-inch arrow can achieve that. ... A stand over 15 or so ...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 ...Jan 1, 2004 · One other thing about comparing rifle cartridges to pistol cartridges, as far as ranges go, rifles usually carry way too much energy for their own good-what I mean by this is a .30-06 or a .300win mag can easily kill a deer at 1000yrds, but there are about 6 guys (non-military) in the world that could make that shot under hunting conditions ... 1. Baseball. A baseball has a mass of 145 grams. How much kinetic energy does this ball have when thrown at 42.2 m/sec?

One of the most confusing concepts for bowhunters today is the application of kinetic energy to their hunting rig. For example, a reader writes: "I have read that kinetic energy of 50 ft./lbs. or more is good for big game such as whitetail deer. Does the kinetic energy change at different yardages?

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 ...

A .22 rimfire typically pushes a 40 grain bullet at 1050 fps, generating 100 fpe. So if we look at the energy delivered by a 16 grain .22 pellet moving at 900 fps and generating 28 fpe, and consider the fact that the .22 rimfire didn’t always do the job, we might be forgiven for discounting the air rifle out of hand.Kinetic energy powers the bullet expansion and penetration that destroys tissue, and it is the destruction of tissue (vital organs if the shot is a good one) that kills the animal. All of the common revolver hunting cartridges (.357 Mag., .41 Mag., and .44 Mag.) are medium bore or big bore calibers. It is no secret that such calibers, primarily ...http://www.deeranddeerhunting.com Deer Talk Now.

My total arrow weight with the 125gr. Broadhead weighs 428 gr. Our shots have been perfect broadside shots, but only punching through one side and not both. I have looking at the Full Metal Jacket 400 @ 10.2 GPI. Which would bring m up to 465g or go to to FMJ 340 @ 11.3GPI and be at 497gr. Work is done on the object leaving it with 25 J of kinetic energy and 30 J of potential energy. How much work is done on the object? An object starts at rest from a height of 50 meters. Its total amount of mechanical energy is 500 Joules. The object begins a free-falling motion; there is no air resistance. When it has fallen to a height of 30 ...

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.What this data translates to is that while .410 slugs may provide sufficient energy within 50 yards, beyond that its efficacy begins to drop dramatically. In fact, according to some ballistician's recommendation of a minimum 1,000 foot-pounds of energy to ethically kill a deer, the .410 is inadequate even at the muzzle.All projectile weapons function by transferring kinetic energy from a weapon into the body of an individual. Ballistics data indicate that denser objects and faster projectile speeds increase the force of impact. 14 KIPs have a wide range of variables that can impact injury patterns and severity, including the material composition, ...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 ...Kinetic energy is one of several factors that can impact how far an arrow penetrates into it's intended target, foam or flesh. The formula for calculating kinetic energy reveals that there are two primary variables - mass and velocity, or in archery terms - arrow weight and arrow speed.Mar 3, 2019. Messages. 4. My total arrow weight with the 125gr. Broadhead weighs 428 gr. Our shots have been perfect broadside shots, but only punching through one side and not both.

In hunting, how much damage a bullet does is more important than its toughness. A bullet that sheds weight and deforms chaotically causes more damage. Conventional mono-metal bullets dump about 50% of their energy in the first 8 inches. Traditional cup-and-core and lead core dump about 80%. Somewhere along the way, the notion that you can ...The bigger the bear, the greater a bolt's kinetic energy needs to be to carry it through the vitals. If you plan to hunt a black bear, your crossbow needs to have at least 40 ft. lbs (kinetic energy). For grizzlies, it should range from 65 to 70 ft. lbs. When your crossbow has higher kinetic energy, your chances of a clean kill will increase.

They penetrate well and stay together. I do ascribe to the 1500 ft-lbs delivered energy for Elk but the 2500 ft-lbs is perhaps now disproven for moose. In my opinion, deliverd energy should at least be 1500 ft-lbs or greater, ideally in the 2000 ft-lb range. After the shot, immediately reload and prepare to shoot again.Question: 21. Two balls of equal size are dropped from the same height from the roof of a building. One ball has twice the mass of the other. When the balls reach the ground, how do the kinetic energies of the two balls compare? A) The lighter one has one fourth as much kinetic energy as the other does. B) The lighter one has one half as much ...Here are the values for 70 mph (31 m/s) and 85 mph (38 m/s) Ok, I am happy. First, this is the acceleration at the maximum compression for a spring. However, my special spring doesn't bounce back ...What makes the .223 potentially deadlier than the .22 is its velocity. When the .223 exits the barrel of a gun, it flies at more than 3,200 feet per second, and is still going 1,660 feet per second after traveling 500 yards. The .22, meanwhile, leaves the muzzle at 2,690 feet per second, and slows to 840 feet per second at 500 yards.Speed alone is not a good indicator of a bows ability to harvest an animal. The question you should be asking is "how much kinetic energy do I need to humanely harvest a deer?" The general answer to that is something around 45 ft/lbs. Kinetic energy is a factor of the speed and weight of the arrow. The amount of KE produced is easily …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.Mark the 8-inch kill zone on your target. Shoot at the kill zone from 20 yards with your 20-yard pin. Your first arrow should hit dead-center in the 8-inch zone, since your pin is sighted in for 20 yards. Now move forward 1 yard and shoot again. Keep moving 1 yard closer to the target with each shot.

At least when these arrows hit the deer they have a decent and more lethal amount of momentum. Let’s review my advice: 6 grains of arrow weight per pound of draw weight for bows in the 70-lb. range. 8 grains of arrow weight per pound of draw weight for bows in the 60-lb. range. 10 grains of arrow weight per pound of draw weight for bows in ...

I have killed a few elk at 60lbs and prefer to shoot 60. My arrow varies from 430-460gr. 29.5 in DL. With elk i always shoot a fixed but deer i shot a mule deer last year with a Rage hypo and it was devastating. I just worry …

May 24, 2021 · This action robbed the arrow of kinetic energy and somewhat reduced overall penetration. On top of that, it was felt that when used on tough quartering-away shots that the blades on one side of the broadhead would be forced to fold back before the others, thus, creating a “cartwheel” reaction that would end in a wounded and lost animal. A .22 rimfire typically pushes a 40 grain bullet at 1050 fps, generating 100 fpe. So if we look at the energy delivered by a 16 grain .22 pellet moving at 900 fps and generating 28 fpe, and consider the fact that the .22 rimfire didn’t always do the job, we might be forgiven for discounting the air rifle out of hand.General Archery Discussion.

The second stone has 4 times as much kinetic energy.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 ...A.30-06 rifle has a hefty 21 fps of recoil. The recoil, which can be felt as bruising on the shoulder, is the result of a large amount of kinetic energy being transferred to the shooter. When hunting deer in Kentucky, this amount of recoil is necessary to kill an animal with enough energy to kill the animal.This weight is more appropriate for whitetail deer and other small-medium sized game. The 243 Win's muzzle velocity hinges on its bullet weight. At 55 grains, its bullet achieves 3,910 fps; at 100 grains, 2,960 fps. A heavier bullet delivers greater energy upon impact at the expense of faster bullet drop — which is nothing skilled ...They penetrate well and stay together. I do ascribe to the 1500 ft-lbs delivered energy for Elk but the 2500 ft-lbs is perhaps now disproven for moose. In my opinion, deliverd energy should at least be 1500 ft-lbs or greater, ideally in the 2000 ft-lb range. After the shot, immediately reload and prepare to shoot again.Physics questions and answers.

Big energy and velocity numbers sell ammo and ego. But marksmanship matters much more than ballistics charts. Consistent 1.5-2″ accuracy at typical ranges translates to reliable kill shots in the field; A poorly hit deer with a .44 isn't better off than an expertly-placed round from a .357; My .357 shoots just as tight as many deer rifles.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.This Demonstration is a model of a real slingshot, which is based on certain idealizations and omissions of features of the real world. A model's reliability depends on the extent to which its assumptions are valid. We have made three key assumptions: 1. All of the energy stored in the elastic bands is transferred to the stone as kinetic energy ...For example, TenPoint's Wicked Ridge Invader 400 crossbow has a 13.5" power stroke, a draw weight of 185-pounds, and shoots a 370-grain arrow at 400 feet-per-second. TenPoint's Wicked Ridge Rampage 360 crossbow utilizes the same stock, flight rail, and bow assembly configuration as the Invader 400, giving it the same 13.5-inch power ...Instagram:https://instagram. optimum mlb network channelw2 publixarrowhead credit union redlands calas vegas caesars palace colosseum seating chart Minimum remaining kinetic energy at impact: 800 ft. lbs. If a cartridge fails to meet any of these minimum requirements it should not be considered an adequate deer cartridge. Based on this, the .25-35 (introduced in 1895) would be about the minimum acceptable 100 yard deer cartridge that is still factory loaded today. heritage funeral home weddington nckim castro khou 11 Doesn't take much to kill a deer at 30 yards. Well tuned bow/arrow, good foc and sharp cut on contact broadhead as well as shot placement will determine success. Sent from my DROIDX using Tapatalk 2 . AT motto,if you can't dazzle em with brilliance,baffle em with BS :darkbeer: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. walgreens dairy ashford and bissonnet 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 ...johnhames. Recurves effectively kill deer with 35 to 45 ft.lbs of KE. But that is getting close to the bounce off level of energy. One of the first deer I ever shot at was with a 50# recurve, 600 grain arrows and a cut on contact broad head at 10 yds. I unluckily hit a rib, I assume crosswise.Imagine that much kinetic energy concentrated into an object the size of a bullet, or a pellet, or a super cool .50 caliber arrow. Now imagine 350 foot pounds in a bullet, or a pellet, or a super cool .50 caliber arrow, and then remember that many PCP’s intended to hunt deer and other types of bigger game will exceed that number.
