[QUOTE="Charles A, post: 223036, member: 231"] Below is directly quoted from Dr. Roberts "As clearly illustrated in the relevant scientific literature over the past 20 years, kinetic energy or momentum transfer from a projectile to tissue is not a wounding mechanism. For that matter, neither is velocity. The amount of energy "deposited" in the body by a bullet is approximately equal to the amount transferred to the body when a person is hit by a fast pitch baseball. The amount of kinetic energy "deposited" or momentum transferred to a body by a projectile is not directly proportional to the amount of tissue damaged and is not a measure of wounding power. Wounds of vastly differing severity can be inflicted by bullets of identical kinetic energy and momentum. What the bullet does in the body--whether it yaws, deforms, or fragments, how deeply it penetrates, and what tissue it passes through is what determines wound severity, not kinetic energy or momentum. In assessing bullet terminal performance, important data is how deeply do they penetrate, how much tissue is crushed and stretched, how is the terminal performance of these loads after first penetrating an intermediate barrier? How have these loads performed during scientific testing by respected researchers, such as the FBI, IWBA, JSWB-IPT? What are the autopsy results from officer involved shootings using these loads?"
