This is a thread for discussion of the article, Arrow Speed and Kinetic Energy, By Jon Henry. Ranch Rifle. Knowing how your arrow speed changes with the increase in arrow weight, you can now easily figure out the new kinetic energy: For instance, if you know your crossbow shoots your current 400 grain arrows with a speed of 400 FPS, our chart above tells you to expect 124. 006" straightness, Deer Crossing Archery's 100% pure carbon arrows are truly at the intersection of quality and economy. Momentum is more important than kinetic energy. Made and designed specifically for the whitetail deer hunter, Barnett's new Whitetail Hunter® STR features a compact, manageable profile that hunters of all sizes and skills can manage. In our example, the computed kinetic energy of the (5 gr/lb) 300 grain arrow was 49. The guy that sold it to me acknowledged the trend of heavy arrows for kinetic energy but preferred to get his KE from a light arrow speed combo that kills deer just fine. For bowhunters looking for a durable, hard-hitting, small diameter shaft that still provides unmatched straightness retention, the Kinetic family of arrows meets the challenge. This will likely kill the deer but make tracking and recovery a little more difficult since the blood trail will be lighter. into Kinetic Energy in the table below. Arrow Speed. The large plate dissipates the energy of the arrow quickly and results in a very shallow hit. They'll increase your bow draw weight max. Using this kinetic energy calculator, it produces 124 foot pounds of kinetic energy! That makes it one of the most powerful crossbows you can buy. FOC stands for Forward of Center balance point. The offseason is here. How much Draw Weight should I need for hunting. 10 Things You Need To Stay Warm While Sitting In A Tree. South Dakota whitetail deer bow hunts always bring a spare release. If your shooting a normal sized fixed blade head I dont see much of a problem shooting a lighter arrow. lbs of kinetic energy. i like as much speed as possible without sacrificing my k. Right now I am shooting a 396 grain arrow at 300 fps. Here are a couple non-hunting examples to help you grasp what momentum is. To use another African example, a crossbow shooting a 500 grain arrow at 350 fps developes about 100 foot-pounds of kinetic energy, sufficient go-power to hunt Cape buffalo or elephant in a compound bow. Constructed of three independently replaceable sections held together by a sturdy interlocking design. You can use 400+ grain arrows to achieve a little more kinetic energy, but keep in mind this will reduce shooting accuracy as the arrows will travel slower and hence experience more drop mid travel. - The bow must be powerful enough (shoot the arrow fast enough) to deliver a kinetic energy of min. into Kinetic Energy in the table below. This bow can shoot an arrow at the downrange of 260 FPS. The question is more related to kinetic energy and the ability of the arrow to penetrate efficiently. A carbon core provides strength without adding too much weight. The 22LR has momentum of 0. We've found it is fantastic for hunting deer. Regardless of what type of arrow you choose, you need to make sure it matches your bow. When starting out, most bowhunters are advised to shoot light arrows with light broadheads so they get faster arrow speeds, higher kinetic energy numbers, and flatter trajectories. It is an embodiment of accuracy and precision with a shooting which makes it one of the best arrows for hunting. But when a 600 grain arrow was fired from the same bow, its computed kinetic energy was 54. 24 foot-pounds of kinetic energy. In the Product Spotlight, Gary Cornum from Easton Archery shows. Its does not take a whole lot to achieve arrow penitration into the lung cavity. So if your new bow setup ultimately shoots a 400 grain arrow at a respectable 250 fps (a typical field-output for a modern rig), your actual kinetic energy or "power" will be:. Welcome To Archer & Angler Welcome to Archer & Angler. When it comes to bowhunting, kinetic energy gets all the love. Easy assembly and take down. 26 J/mm(2)) are similar to bolts discharged by pistol crossbows. When hunting bigger game, heavier arrows are preferred by some but speed is then sacrificed. Archery is a sport that is good for the mind and the body which benefits me greatly for my health and wellbeing. When the arrow compeletely stopped it would transer all it's energy to the deer, where the broadhead tipped arrow would have passed through the animal. If you search this question in a lot of online forums you will hear every answer imaginable. You need more kinetic energy – or knockdown power – than required for deer to bring a bull or cow elk to the ground. There are several factors that will determine the success you experience on a real hunt out in the field. Archery Message Boards. They also state 55 ft-lbs of kinetic energy would is sufficient for most popular North American game species. But it’s also got something for me in other ways. Kinetic energy The kinetic energy is as vital as speed when you were looking for the best crossbow to buy. We need to figure out the kinetic energy (KE) of the arrow. But, as this model has a draw weight of 55 pounds, it is enough to bow hunt at least a deer. The superior construction has the ultimate spine consistency, making it excellently accurate and durable. A bullet, because it is moving so fast, has incredible amounts. of Kinetic Energy, the Warhawk has enough power to take down any whitetail deer! Weighing in at just over 5 lbs. Kinetic energy of an arrow can be found by using the formula KE = (mv ²)/450,240 where m is the mass of the arrow in grains and v is the velocity of the arrow in fps. Here you can ask questions or make comments about the article. This is a crucial point especially for hunting, as KE ultimately determines how hard the arrow will hit the animal. I see the big mechanical broadheads recommend a bow with" high kinetic energy" to ensure penetration,but nowhere do I see what level is considered "high energy". It appears that you have a clear shot into the chest cavity, and if you were hunting with a rifle, it’s possible to land a fatal shot. Since those shooters have very low kinetic energy numbers they have to have as much momentum as possible out of their setups. In order to determine the kinetic energy, you must know the velocity of the bullet and the weight of the bullet in grains. However its been said and written that 25 KE should be a minimum for deer sized animals. The blades of a mechanical broadhead are deployed in flight, thus raising the level of lethality against the target. Both carry 100 ftLbs of Kinetic energy. Then going heavier helps with penetration. For the purpose of archery, we measure kinetic energy in foot-pounds (ft/lbs. Too low will lack penetration but too high will make the arrow awkward to shoot and will cut down your range. arrow will outperform a light arrow, even if the kinetic energy number is the same between the lighter vs heavier arrow (when all other factors are equal). Easton Beman ICS Hunter Patriot Factory. At the end of the day, you have to assess your bow and arrow setup to decide what the best choice is for you. Its velocity will assure you good groupings as good at 70 yards. Kinetic energy is more important to me than speed. Now we do the math. Rage is the world leader in lethal broadhead technology. This is because the lighter weight allows for faster acceleration, which also causes the arrow to hold its trajectory better and lets off a faster shot. 06 with a normal load and 9g bullet and a muzzle velocity of 800meters per second) is 2880 joules. Kinetic energy is the work that the arrow will do. Momentum, by comparison, is the genius, recluse cousin few people talk about, but who has a cult following. It is related to power stroke and draw weight. Kinetic energy is used to measure the mechanical efficiency of a bow. The problem is that they often also get poor penetration and start losing animals. Kinetic energy? Discussion. 55 Foot Pounds for: Medium Game such as Deer and Antelope. Totally retarded. 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. Spin 400 carbon arrow. 950-1000 grains are preferred. speed gives you a flatter shot (allows more distance errors). Momentum is MUCH more important than kinetic enenrgy.

Mass Weight 3. However, with its ability to fire bolts up to 400 fps behind 140 ft. The kinetic energy, that is, the force of impact, is about 58 foot-pounds. We need to figure out the kinetic energy (KE) of the arrow. Think of kinetic energy as the amount of punch your arrow has when it hits the target down range. Don't think it happens? Watch nearly any hunting show, and you will see deer running off with over half the arrow sticking out. You can use 400+ grain arrows to achieve a little more kinetic energy, but keep in mind this will reduce shooting accuracy as the arrows will travel slower and hence experience more drop mid travel. Momentum is more useful for hunting purposes because it is based on mass. 5 inches power stroke, the Ravin R29 measures 29 inches in length and weighs 6. In preparing for a moose hunt, I took Gold Tip carbon arrows and inserted weedwacker plastic string into the shafts. Its unique, high-performance carbon construction is lightweight and fast, and delivers the kinetic energy needed to drop a whitetail deer. Consider the power of your crossbow. So both speed and mass matter. Most current bows which are tuned can shoot an arrow as close as possible to the 5 grains per pound of draw rule and still have plenty of kinetic energy to kill a whitetail deer. If you're shooting well above the recommended kinetic energy and have a deep penetrating arrow & broad head combo, your arrow may still reach the vitals but stay in the deer. It looks like the regs Jerome posted are speaking of minimum arrow weight and kinetic energy, and do not mention draw weight of the bow. pronghorn and white-tailed deer. Thus, it may. Lighter arrows will increase the speed at the expense of momentum, making it harder to bring down bigger game like a buck deer or bull elk. 380 grain arrow at 308 fps, with a foc of 11. Total kinetic energy depends upon two variables: the mass of the object and the speed of the object. If you are interested in calculating the kinetic energy of your bow and arrow setup, I highly recommend using this calculator from BackcountryBowhunting. Whitetail deer require a broadhead with a cutting diameter of at least 1 inch and larger deer, such as elk, require heavier broadheads with larger cutting diameters. Recommended Kinetic Energy for Hunting Whitetails. Note this is especially helpful when having the precise speeds of your setup at the yardage your shooting. To discover the AMO Speed a bow is set at 60 pounds, with a 30-inch draw and shooting arrows that weigh 540 grains. How fast the bow shoots.

Rage built their name on the unique and patented SlipCam™ Technology, rearward deploying mechanical blades that deploy and cut unlike any other mechanical broadheads ever. I have been thinking about bumping up my arrow weight, but am wondering if I even need to. Compound Bow Kinetic Energy Kinetic Energy (KE for short) is described as the energy stored within a moving body. 24 foot-pounds of kinetic energy. You will need to provide total arrow weight and initial speed for the calculation to be effective, as well as some other optional info (see below). Velocity simply is the speed in which your arrow travels. with a draw length of 29″. The added weight keeps more of the kinetic energy pushing the arrow in a straight line upon impact, especially when impacting a non-uniform target (think deer). Everyone is so caught up in the speed of the chronograph that measures the bow; he or she lose an idea how energy produces a lot of kinetic penetration and arrows. This measurement results from the relative weights of the components used in the arrow: shaft, insert, head, fletching and nock. KE is a useless number and it drives me nuts that the archery industry has adopted it. The Barnett Penetrator crossbow arrow flies with a speed of 350 feet per second and has a kinetic energy of 109 ft lbs which makes it strong enough to penetrate the thickest target. Most crossbows produce plenty of kinetic energy to use all Swhacker mechanical broadheads. In order to start moving, they had to get that energy from somewhere. Lots of hunters swear by KE, and they do whatever they can to maximize it with their bowhunting rigs. Since the introduction of the Injexion (4MM) ultra-micro-diameter hunting arrow, the field reports have been compelling—the friction reduction increases. The new R29 is an incredible 5. Kinetic energy. The professional hunter should assess arrow placement and determine if the depth of penetration is lethal. You can find scads of articles extolling its virtues and charts describing its professed impact. 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. A lighter arrow that shoots faster out of your crossbow may be a great arrow to use for competitive target shooting, but it may not be the best one to use for hunting. A 60-pound short draw bow might lob a 650-grain arrow at low speeds, but with a sharp broadhead that arrow will zip through. The kinetic energy will be based on the draw weight and length as well as the weight of the arrow and the height of the brace. All game except moose can be harvested by bow and arrow. Early season goose hunting opportunities for North Dakota Sportsmen. We have practical how-to's, hunting tips, exciting stories, and related ways to maximize your primitive experience. You will regret it. Your xbow manual should tell you your xbows k. Heavier bolts have more kinetic energy, are quieter, and more resistant to wind drift. This is important because a projectile with greater momentum is more likely to penetrate bone and flesh. The longer the power stroke and higher the draw weight, the more powerful the arrow becomes because of the energy transferred to it. Kinetic energy is calculated by the following formula: Kinetic energy = ½ x Mass x Velocity^2. Maybe an elk, tooor even a moose! How much kinetic energy do I need to get that done? This is not a channel about shooting big bucks. All of the passthrough shots I have seen the arrow is just lying on the ground or stuck very loosely, having expended most of the kinetic energy passing throught the animal. Thus, it may. These arrows are the best for hunters that are after the accuracy. Momentum is it's persistance to remain in motion and is what an archer needs.

Here you can ask questions or make comments about the article. of kinetic energy 125-grain, 2 1/4-inch cut 60 ft. Used to build things like high-performance fighter jets, carbon’s strength-to-weight ratio is unrivaled. This is because energy is proportional to the mass of the arrow but also the square of the velocity. In the world of physics, kinetic energy is described as the energy stored within a body in motion. Arrow configuration: Carbon/aluminum/wood, arrow diameter, broadheads/field points, bullet point vs. The Rampage by Black Eagle Arrows is an exceptional hunting arrow with no sacrifices to durability. This will affect kinetic energy. Mass and speed= kinetic energy. In our example, the computed kinetic energy of the (5 gr/lb) 300 grain arrow was 49. Rage is the world leader in lethal broadhead technology. For example, if an arrow takes a nosedive soon after leaving the bow, the kinetic energy won't be delivered with the broadhead straight on, and the momentum can also suffer. Easy arrow removal. Momentum is calculated by P=M*V where P represents momentum, M represents Mass (weight) and V represents velocity aka speed. This is a thread for discussion of the article, Arrow Speed and Kinetic Energy, By Jon Henry. This is not anecdotal. Maybe an elk, tooor even a moose! How much kinetic energy do I need to get that done? This is not a channel about shooting big bucks. Mass Weight 4 LBS. 280 (speed) x 280 (speed) x 423 (weight) / 450,240 = 74 (lbs.
