Results of experimental research of wound ballistics of separate types and calibers of modern bullets

There was made the analysis of wound ballistics modern expansive bullets in comparison with shell on 25 blocks ballistic plasticine (ROMA PLASTILINA No. 1, Ballistic Testing Backing Material), USA, which one shot from an AKS-74 automatic firearm and carbine ZBROYAR Z-10 optical sight fired. The bullet speed highest 5.45x39 caliber cartridge a V-max bullet. – 1185 m/s, low .308 Win SP, 664 m/s. difference is significant at level significance ?=0.05. In terms size entrance hole, largest SP 10.0 cm, smallest - "PS" steel core mm, sample year 1974 (7H6) 1.2 cm. type "V-Max" shortgun hole 9.1 asterial shape having radial gaps turned edges outside. All cartridges did not have exit after shot. dimensions formed residual cavity were firing 25.0x5.0 cm., military mm 6.0x4.0 character for all bullets, contrast to (7H6), where no such changes are detected. considerable signs expansion properties deformation form "flower death" identified other showed fragmentation, location fragments both outside its borders different distances. Expansive differ significantly flight (m/s) BTHP due their structure, weight, caliber. Bullet has design properties. Common blind nature lesion presence large cavity, kinetic energy return 114.37 E, J/mm2 inside object lesion. Fragmentation occurs located A causes s by "death flower" causing damage.
