So, it is indeed legal to hunt Cape buffalo with a .45-70 Government in those countries. On the other hand, Zimbabwe requires a minimum caliber of 9.2mm and a minimum energy of 5,300 Joules (3,909 foot pounds) for hunting "Class A" game like buffalo, hippo, and elephant. Namibia has a minimum energy requirement of 5,400 Joules (3,982 foot ...As bowhunters, we have one goal. A well executed shot & perfectly placed arrow providing a clean passthrough. I want you to read that last line once more and...The military did not adopt the 5.56 to make humane one shot kills on a 180 lb man. It adopted it to allow soldiers and marines to carry hundreds of rounds to allow for better suppressive fire, more wounds and maims, and some kills. The urban legend is one enemy was killed in Vietnam per 50,000 rounds fired.For ethical deer hunting with a bow, it is recommended to have a minimum of 25 ft-pounds of energy. 1. How do you calculate ft-pounds of energy for a bow? You can calculate ft-pounds of energy by multiplying the draw weight of …

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 ...Ballistics Insights. The 7.62×39's typical 2,350 feet per second muzzle velocity is about 750 fps slower than the 5.56×45's. 7.62×39 ammo will therefore exhibit the same velocity at 300 yards that the 5.56 will at 500. The 7.62 may have a steeper bullet drop, but its heavier bullet delivers about 200 ft lbs more muzzle energy than a 5.56.Hunters aim to kill. In addition to being a Level 2 U.S. archery coach, Mark Beck is a hunter and an engineer with Plano Synergy who has experience in designing both arrows and crossbows. He makes no secret which side of the argument he's on. "I want more kinetic energy to drive that broadhead through," he said.

In a car crash where the occupant increases the speed by 10%, for instance (77km/h instead of 70km/h), the energy, and consequentially the extent of your injury, will go up by 20% per cent. Conversely, the same happens when you decrease your speed - reducing your rate by 10 per cent means decreasing potential injury in a crash by 20 per cent.

We would like to show you a description here but the site won’t allow us.Those weighing 20-35 lbs require 35-50 foot-pounds of energy to kill, and those weighing 50-75 lbs require 80-100 foot-pounds of energy.

We are not talking about 1 ft lb of energy, we are talking about 4800 ftbs. If most of that energy was transfered into thermal energy, it would blister your finger to touch the target or bullet.

Velocity is the main contributing factor to kinetic energy, which packs the punch that makes quick ethical kills. In a given calibre, the lighter bullet is faster and so it can produce more kinetic energy. ... many experts say to kill a deer ethically takes terminal energy of 1,000 foot pounds (ft-lb), some say 800 ft-lb, and others commonly ...

Kinetic and potential energy are both typically ascribed as forms of mechanical energy and can be interchangeably converted. Potential energy can be converted into kinetic energy a...

If you want a good balance of energy and flat shooting, you can use a 180-grain bullet that has the energy to kill a deer at 700 yards and elk at 500 yards. For 90 percent of shooters, 700 yards is too far to shoot. Most people think this much energy is a good thing, but if you are hunting deer where most shots are 100 yards with too heavy of a ...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.Feb 8, 2019 ... You have surely heard and may possibly believe that the killing power of a cartridge is represented by kinetic bullet energy.For 300 blackout deer hunting, supersonic 300 BLK rounds can be suitable under the right conditions. A projectile with the weight of 125 to 140gn has double the speed of subsonic loads at around 2,350 feet per second. Within a hundred yards, supersonic 300 BLK rounds will tumble reliably and transfer energy thoroughly into tissue — enough to ...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.

There's a lot more to it than raw energy. My recurve only generates about 45 ft lbs of arrow energy, but can kill a deer from massive hemmoraging in 15 seconds with a double lung shot. As you noted, a round ball sheds its energy rapidly. Shoot enough gun, get up close, wait for the right moment, pick a spot, give thanks for success.When hunting for big or small game, we need to look at the pellet's weight multiplied by the Velocity Squared, divided by 450395. Conventional wisdom has held that 1,000lbs foot-pounds of energy are required to kill a deer.

This means that the Kinetic Energy of a 400 grain arrow, shot from your specific bow using our example’s specific settings (50 lbs. and 28″ draw) will result in 51.17 ft-lbs of kinetic energy. Kinetic Energy Deterioration Rate. In our above example, we’ve calculated Kinetic Energy to be 51.7 ft-lbs.Car Energy Kinetic Kinetic energy Speed. In summary, the original speeds of the two cars were v1 = v2 and v1 + 8.5 = v2 + 8.5. This was determined by setting up the conditions properly, where one car has twice the mass of the other and only half as much kinetic energy. By increasing their speeds by 8.5 m/s, both cars then have the same kinetic ...How much kinetic energy is lost in the collision?

KE = (arrow weight / 450240) x (velocity x velocity) Usually the advertised fps rating is achieved using the lightest arrow recommended for the bow. For example, a bow that uses a minimum arrow weight of 350 grains achieving 305 fps would have. (350/450240) x (305x305) = 72.3 ft/lbs of kinetic energy.

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 ...
