DoP = maximum equivalent depth of penetration in calibrated ordnance gelatin (or soft tissue)
Wound Mass = total weight of tissue damaged/destroyed within the entire wound channel
P
[I/H] = probability of incapacitation per random projectile strike to assailant's torso/abdomen: 30-second Assault modality, (Dziemian US Army BRL P
[I/H] model)
ΔE
15 = amount of kinetic energy, in fpe, expended by the bullet from a penetration depth of 1 through 15 centimeters
The average predicted penetration of 11.387 inches for the Winchester USA .45ACP 230-grain JHP, which used to be part of Winchester's Super-X
[emoji768] ammunition line, is just shy of the F.B.I. test protocol recommended minimum penetration depth of 12 inches. Expanding robustly upon impact to ~1.625x its initial diameter and with terminal penetration approaching 12 inches, this JHP is capable of destroying nearly 2.4 ounces of soft tissue per strike with the entirety of that damage occurring within the typical human body assuming that the expanded Winchester USA .45ACP 230-grain JHP remains within an assailant's body. Weight measurements of the recovered test projectile were obtained using an RCBS Model 505 magnetically-dampened reloading scale. The test projectile's jacket and core remained together throughout the entire penetration event.
