How much kinetic energy to kill a deer.
It’s only from 300 FPS and up that you get enough kinetic energy at all feasible hunting distances (up to 50 yards) to be able to comfortably hunt elk. As such we recommend that elk hunters stick to 300 FPS or more. For whitetail deer this requirement is lower – any crossbow 250 FPS and up will be a safe pick.
Mar 18, 2014 ... I know that for deer you want to be over 40 ... 68 momentum I don't really know how much power that is. ... kinetic energy. Sectional density and ...From there, a simple formula reveals the precise energy: Velocity (fps) x Velocity (fps) x Weight (grs.) divided by 450,240 equals Energy (ft.-lbs.). For example, let’s say you shoot 500-grain arrows at 250 fps. Using this formula, 250 x 250 x 500 divided by 450,240 equals 62.47 ft.-lbs.Watch on. View More Deer Hunting Gear. Calculate your own arrow's kinetic energy and momentum using this equation, and find out what's needed to kill deer and other wildlife.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?
Therefore, the heavier the missile, the more kinetic energy there is. Overall, it takes around 21 to 45 Joules of kinetic energy at the point of impact to pass through any large-sized animal. Body movement after a shot. There are certain telltale signs that show the hunter where the animal was hit based on the movement of the animal right after ...
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!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.
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.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.For example, any given body has kinetic energy if it is in motion.

New Hampshire. "Experts" will tell you anywheres from 1000-1200 ft/lbs. This, to me, is waaaaay overkill. One gentlemen, whos advice I trust completely, has a good formula. 3 times as many ft/lbs is needed than the games weight. Meaning if you want to shoot 200 lb deer then 600 ft/lbs should do the job very nicely.
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.
Kinetic energy (often referred to as KE) is the energy that an object possesses by virtue of being in motion. We find that by taking one half the arrow's mass times velocity squared. To simplify, think of it this way: KE is the energy an arrow stores while in flight. Momentum is the ability to maintain energy upon meeting resistance.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.Mar 3, 2019.
