![]() Understanding Kinetic Energy Kinetic Energy FormulaĪny moving object creates kinetic energy. You certainly do not want to rely solely on luck to save your life. 22 rim-fire out of a short revolver, hitting the head or heart in a scary, confusing, fast moving altercation is not easy. While you may be able to consistently hit the “10” ring on a paper silhouette or the head on a paper figure, that is not the real world. If you plunk the thug in the heart or cranium it will take the fight out of them quickly. Shot PlacementĪll things considered, shot placement is what will get the job done quickly with any caliber of bullet. The weight and size of the bullet is key to determining “stopping power.” The type of bullet: hollow point, frangible, ball/full metal jacket (FMJ) or plated determines how the projectile acts when it hits the target. And the kinetic energy directly correlates to the severity of the injury and how quickly the shitbag is incapacitated. The release of kinetic energy into the violent thug is the most important of these five factors and depends wholly on each of these factors. The closer you are to the bad guy the more damage a well placed shot will do. Distanceĭistance to the bad guy correlates directly to how much kinetic energy is slammed into the thug’s vital tissue. But it is a proven fact that a larger caliber (diameter) projectile will create a larger wound channel. 22 short rifle to a 50 BMG, can dispose of a bad guy. ![]() The placement of the shot determines the amount of kinetic energy absorbed by the target’s tissue. The size/weight/type of the bullet + the distance to the target determines the kinetic energy the projectile will deliver. Type, size and weight of the projectile/bullet.There are several things which need to be understood to understand what creates “Stopping Power.” Key Factors Determining Stopping Power 380 ACP in its place, I am guessing it may have changed the stacked rankings a bit.īut one comment on my poll caught my attention: 357 SIG cartridge was included because it is my favorite caliber. 38 Special/.357 magnum would have done well also, but since I no longer carry revolvers, I only included the semi-auto calibers. 9mm is by far the most popular cartridge in semiautomatic pistols. These results do not surprise me in any way. The poll is now closed and the final results are: 357 SIG – the latter of which is my favorite caliber. Twitter polling does not allow a lot of choices in their polls, so the options I provided were. So yesterday, I posted a poll on Twitter asking everyone what caliber pistol was their favorite. While I am by no means an expert on ballistics and the physiology of a mortal gun shot wound – I am very well read on both. Additionally, I have shot both pistol and rifle competitively for many years. I have trained in self-defense for many years including the following disciplines: Close Quarter Combat (CQB) with firearms and fixed blade knives, batons and Krav Maga. So, besides having ridden millions of street miles on two wheels, I am very proficient and knowledgeable about firearms and self-defense. Many of your are aware that I write self-defense/Second Amendment articles each month for several widely read publications.
