Bullet size: The larger the bullet, the more resistance and the larger the permanent tract Bullet deformity: Hollow point and soft nose flatten out on impact, resulting in a larger surface area involved. Expansion and Penetration. Its as if the damn thing was DESIGNED to ricochet. dont worry, i have a good reason for asking. They are more durable and withstand rough handling on the battlefield. Hollow-point and soft bullets are designed to flatten and spread, creating a wider area for their tracks and increasing the damage caused by shock waves and cavitation. So, hollow-points are designed to expand, causing their diameter to increase as they pass through the target. The latter refers to a round tip, ball, target ammunition. Wound Ballistics: Medium and High velocity wounds It is ammunition with a hole at the tip. Its purpose is to slow down the journey of the bullet and expand itself once it hits a barrier such as a wall or flesh. Because FMJ bullets do not expand, they are more effective at piercing armor. As the bullet enters the body it crushes and shreds tissue in its path this creates a permanent cavity the bullet hole. this is not any cry for help or anything like that. In addition, the energy of the impact is dissipated in a shock wave that radially flings surrounding tissue away from the path of the projectile, creating a cavity larger than the diameter of the bullet https://www.pbs.org/newshour/nation/what-a-bullet-does-to-a-human-body What Is a Hollow Point? Update: what im really curious about is, would the bullet go "straight through" as they say in the movies or would it blow a hole in a person. Contrary to popular myth, hollow-points do NOT expand while flying through the air! Unless a hollow-point bullet strikes something hard, its unlikely to fragment. There are also soft point bullets which fill a gap between full metal jacket and hollow point ammunition. https://www.targetbarn.com/broad-side/jacketed-hollow-point The hollow point bullet, by contrast, has a nose that is literally shaped like a cookie-cutter. Hollow point bullets have a concave center that is usually lined with lead or similar material. Based on this information, we can make some conclusions about the areas you might least like to take a bullet Their rounded tips permit proper transit up the feed ramp, whereas the usage of hollow point bullets can cause failures to feed. Both hollow and soft point bullets are designed to expand upon impacting a target while fragmenting inside. how much damage would a .38 caliber revolver with hollow point bullets do to a human body or head? While any bullet can ricochet on an extremely acute angle, the supposedly more humane round nose non-expanding bullet is MUCH more likely to do so.
