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.And it uses the estimated energy for one shot kills on game. It uses a recommended energy and a minimum energy for each animal. On Elk it recommends 2000 ft/lbs and 1500ft/lbs as a minimum. this is at the Point of Impact. Deer are 1200 ft/lbs and 1000 ft/lbs minimum. These values are conservative but are a good place to start.At 50 yards downrange, a typical .357 Mag. bullet is traveling about 1,100 feet per second. That is 750 mph. Despite its power, recoil is more manageable with the .357 Mag. than with the .44 Mag., as the latter requires a bit of masochism if you are to enjoy even a half-hour shooting session.This requires power—kinetic energy—applied to the animal's body sufficient to cause massive, immediate trauma to its vital organs. ...

This balance of speed and weight provides the …A subsonic round and a 44mag throwing 240-300gr bullets kill in very different ways. "Power" doesn't even make sense, I don't care what the kinetic energy numbers say. A sub is essentially a broadhead, if you are smart enough to choose one of the few bullets that can expand at such velocities (IMHO a broadhead is better).Let's say you're shooting a heavier arrow that weighs 500 gr. That means it has about 64 ft-lbs of kinetic energy when it leaves the bow. During the flight, some of that energy will be lost to wind resistance. When the arrow makes the impact with the deer, all of the remaining energy is transferred to the razor sharp edges of the broadhead.For deer hunting, popular rifle calibers include .243, .270, .308, and .30-06, all of which offer sufficient power and accuracy for taking down deer. 1. What is the best rifle caliber for deer hunting?

You need to find out your arrow speed and then calculate K.E. The formula is: speed x speed x arrow weight / 450240., 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. , For instance, Hornady's popular 250-grain 20-gauge SST sabot slug produces 1,200 foot/pounds of energy at 100 yards, 983 foot-pounds (ft.-lbs.) at 150 yards, but then tails off to 815 ft-lbs at 200. Many state DNRs recommend 1,000 ft.-lbs. of energy at the target to anchor a deer, but there's no data that has shown that to be the benchmark., Max Speed: IBO arrow (5 grains/per pound of draw weight). Max Efficiency: arrow ~10-15% over IBO (5.5 grains/per pound of draw weight). Max Energy: arrow ~20% over IBO (6 grains/per pound of draw weight). Shoot three arrows and use the average of the three shots. Enter speed and arrow weight data into the calculator., For deer hunting, a crossbow with a FPS (feet per second) of 300-350 is ideal as it provides enough power and speed to effectively take down a deer without causing excessive damage to the animal. ... Using a crossbow with a lower FPS for deer hunting may result in an inadequate amount of kinetic energy, potentially causing the animal to suffer ..., 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., Summary. If you don't care about hitting a target, a powerful modern crossbow can shoot as far as 500 yards. If you want to hunt, up to 80 yards is possible for a very skilled shooter, however you should stick to a maximum of 60 yards, and preferably much less than that (30-35) if you are a beginner. For target practice, everything will ..., 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.

A fast arrow travels around 300 fps, but sound travels at about 1,225 fps. And whitetail's reaction ..., By definition, kinetic energy is the capacity to do work. It is the TOTAL ENERGY of a body in motion. K.E. is scalar, or non-directional, in nature. As applied to an arrow in motion, K.E. includes such things as: radial energy due to arrow flexion, rotational energy due to arrow spin, sonic energy due to vibration, heat energy due to friction ..., Max Speed: IBO arrow (5 grains/per pound of draw weight). Max Efficiency: arrow ~10-15% over IBO (5.5 grains/per pound of draw weight). Max Energy: arrow ~20% over IBO (6 grains/per pound of draw weight). Shoot three arrows and use the average of the three shots. Enter speed and arrow weight data into the calculator.
