A study into the viability of Synbone ® as a proxy for Sus scrofa (domesticus) ribs for use with 7.62 × 51 mm Full Metal Jacket ammunition in ballistic testing

This study aims to determine if Synbone ® flat plates could be a viable proxy forSus scrofa (domesticus) ribs in ballistic testing with 7.62  × 51 mm Full Metal Jacket ammunition. 5 mm, 6 mm and 12 mm quartered Synbone® plates were embedded into 10% ballistic gelatin and shot using 7.62 mm ammunition. The models were then analysed to compare the Synbone® to a previousSus Scrofa (domesticus) rib study and focused on energy deposition, the number of fragments within the block, angle of deviation, onset of yaw, the temporary cavity, and the permanent wound channel. No significant difference was seen between theSus Scrofa (domesticus) and the 5  mm Sybone®. There were significant differences observed betweenSus Scrofa (domesticus) ribs and 6  mm Synbone® for the number of fragments, energy deposition and projectile tract diameter, and significant differences seen betweenSus scrofa (domesticus) ribs and 12  mm Synbone® for the depth of onset of yaw, energy deposition and projectile tract diameter. This study indicates that the 5 mm Synbone® plate is a suitable proxy forSus scrofa (domesticus) ribs for use with 7.62  × 51 mm FMJ ammunition in ballistic testing.
