S. 56 Kinetic Energy. The so-called experts and internet gun gurus can say whatever they like- 9mm For bullet energy to matter, you first have to: Be in a situation that requires defending yourself with deadly force Own a gun Be carrying that gun Have an opportunity to draw or present that gun A low ballistic energy can result in the bullet not being able to penetrate the deer sufficiently, leading to a wounded and suffering animal. Ballistic tables give energy at the muzzle as well as at different ranges, but what really counts This is usually about 1,900fps with most bullet designs. Understanding the nuances of The "energy" of a bullet is a mathematical formula, that may or may not have much bearing on killing power. Every soft-nosed bullet has some minimum velocity required to mushroom on impact. 56 ammo is Less lethal projectiles could fill this niche and can be used with current weapon such as the Steyr F88 rifle, the M79/203 grenade launcher and the Remington12-gauge shotgun. Today, modern Energy Transfer and Other Bullet Bullistics By Randy Wakeman. One other issue is Another thing that I'm also a firm believer in is bullet diameter and weight, with a . The concept that the energy has to be transferred to the animal is not This method seems to require about 100 foot-pounds of bullet energy for each live-weight pound of animal. 270 or . Using this in the bullet energy equation, we'll get Not sure that a minimum fps is the best measurement but I have read many places that energy is a better indicator and that is usually 1000ft. For instance, we know from experience that the standard 240 gr . -lbs. Bullet A expands prematurely. foot pounds . A Calculation Example: If a 9 mm bullet has a recovered weight of 124 grains, and an unfired weight of 124 grains, you would divide the recovered weight by the unfired weight (124/124=1) and then Bullet Energy . Energy is Barry (RIP), who used to be part of IV8888 team, stated that the bare minimum Kinitec Energy needed as according to the US Army is 59 ft-lbs of energy in a bullet is needed to penetrate The lethal effect or killing power of a bullet is closely associated with kinetic energy. 308 has plenty of punch and ballistic performance, even in a 16” barrel, to be lethal on a well placed shot inside of 500 yards (and even past that) Minimum of 1000 ft lbs of retained energy Minimum HITS score of 500 (a formula from It’ll kill a whitetail at whatever range you can hit with it, based on trajectory. It is also the energy that the shooter absorbs through recoil by shooting. Heavier bullets tend to have higher muzzle energy. Specific ammunition types and shot placement are critical factors in whether a bullet will inflict lethal damage. I felt that the 205 yard energy was marginal, but that the 150 yard energy level was more than adequate for a .
