Oct 1, 2014. #9. I agree with what has been said, and also use a ballpark of 1500 ft*lbs as a minimum energy for elk. Although, I have never had the opportunity to test 1500 ft*lbs. My furthest shot on an elk still carried over 1850 ft*lbs at 630 yards with a barnes .338 210 gr TTSX.

Kinda not really. The old fuddy has like 30% more energy in a like for like load, with some real world loading figures getting up to 40%. Nothing wrong with a 300blk, and they kill deer just fine but the comparison to 30-30 isn't an accurate one, the old 30 hits quite a bit harder.At the end of the day, the question of draw weight doesn't matter as much as it once did to bowhunters — but 40 pounds is still a good starting point. Lighter than that will work, too, so long as you know the constraints and make the proper adjustments to your equipment. Get your camo fix at the Realtree store.The muzzleloader has 2,680 ft.-lb. of energy at the muzzle and only 1,180 ft.-lb. at 200 yards. At 243 yards, the bullet falls below 1,000 ft.-lb. of energy—the widely accepted minimum needed to ethically kill whitetail deer. With even a 10 mph wind, the 250-gr. Barnes will drift 10.91 inches at 200 yards.For example, our energy data showed that the .300 blk did not have enough energy to kill a deer just after 150 yards. Now I will not consider the 300 blk a great round for deer, but if the quarry is within 120-150 yards, you can give it a shot and be successful. However, the .300 blk is a perfect hog medicine.January 18, 2006 - January 5, 2007 RL33240. For some time, U.S. ballistic missile defense (BMD) programs have focused primarily on developing kinetic energy interceptors to destroy attacking ballistic missiles. These efforts have evolved over 30 years and have produced a significant amount of test data from which much can be learned.The 308 Win's .308" bullet is commonly available in 150, 165, and 180 grain weights, which are substantial enough to make short work of a great variety of game. In experienced hands it can hit a 1,000 yard target. Many have noted the 308 Win's shortcomings, often attributing a great deal of its popularity to mere tradition.

The term kinetic …Kinetic energy is energy in motion. A 150-grain bullet standing still has potential energy. Dropped, it has a bit of kinetic energy, and you’ll feel this should it land on your naked toe. Push this same bullet with about 50 grains of Hodgdon 4350 powder behind it, and you won’t want to feel it on your toe or anyplace else. It will be ...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.Oct 6, 2016 ... The larger number is recommended, but the lesser number will work on a smaller deer. To hunt for large game like a grizzly bear, you need ...Yes, the .223 Remington is clearly a more powerful cartridge than the .22 Hornet. Similar to the 10mm vs .45 ACP debate, the .223 Remington has more energy remaining at 200 yards than many .22 Hornet loads have at the muzzle. However, the body of evidence also indicates that both cartridges are very effective on predators, small game, and varmints.

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 …At the end of the day, the question of draw weight doesn't matter as much as it once did to bowhunters — but 40 pounds is still a good starting point. Lighter than that will work, too, so long as you know the constraints and make the proper adjustments to your equipment. Get your camo fix at the Realtree store.The .22-250 Remington will throw a 60-grain pill at least 3,600 fps. Sighted dead-on at 200-yards, it will drop just 5.4 inches at 300-yards and still be packing 816 ft. lbs. That's 300 ft. lbs. MORE than the 30-30 Winchester with a 150-grain flat nose. A .22 caliber bullet with enough energy down range is perfectly capable of killing a deer ...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.All but the .243 are still carrying the generally accepted 1,000 ft.-lbs. of energy necessary to kill a deer out to 500 yards, which I grant you is farther than we have any business shooting at deer-size gam. At the far more practical distance of 300 yards, which is still a long shot, every cartridge on that list will kill a deer, antelope or ...We would like to show you a description here but the site won't allow us.Oct 19, 2019. #1. Just an update for those interested in using this 6.5 Grendel on deer. My hunting buddy took his son out yesterday for our youth rifle season and he was able to harvest a young buck. He was shooting his dads custom built AR-15 using the Hornady Black ammo loaded up with the 123 eld-m. Shot was about 50 yards quartering to.An FPS of 300-350 is considered ideal for deer hunting with a crossbow. 2. Can I use a crossbow with a lower FPS for deer hunting? While it is possible to use a crossbow with a lower FPS for deer hunting, it is not recommended as it may not provide enough speed and power for a clean and ethical kill. 3.

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.

Dec 1, 2012 · 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. When chest shooting heavy game, a heavy but stout controlled expanding projectile driven as fast as the shooter can manage produces the fastest possible killing. As O'Rourke said, use enough gun. Use enough gun. The .338 Win Mag and controlled expanding 225gr Nosler Partition can be put to great work on bear. Someday I'd like to hunt bears with my crossbow.

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.For a small deer like a fawn you will need around 30 foot-pounds of energy to kill it. For a medium-sized deer like a doe you will need around 40-50 foot-pounds of energy. For a large deer like a buck you will need 60+ foot-pounds of energy. As for where you should aim it depends on what kind of weapon you are using.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.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).#2 · Jul 20, 2004. Will this set-up kill a deer with a well placed shot? Absolutely. Will yyou get a complete pass through? Doubtful. Most recommend at least 40 ft-lbs for a pass … The Deer Hunting is Located in 1017 Cambridge Court, Paris, AR, Arkansas, 72855.
