On impact soft cored bullets are designed to deform. The interaction between core andjacket during the penetration process is of particular importance if bullet performance is tobe optimised. A bullets jacket serves several core purposes: (1) engagement with rifling; (2)inertial confinement, and; (3) cushioning on impact. In the latter two cases the jacket isprimarily acting to control the nature of the stress / shock loading within the round both onand post-impact. In order to further inform armour design, via both dynamic (flash X-ray)and post-mortem (microstructural and X-ray computer tomography) analysis of impact /penetration events and recovered targets, an attempt has been made to provide additionalinsight into the bullet penetration process and the influence of the jacket on the same.
