Ragsdale gunshot wound study
Pathologist Bruce D. Ragsdale conducted experiments in the 1980s to show the effects of different types of gunshots on human bone and tissue. He encased leg bones from cadavers in blocks of transparent gelatin and then fired different types of guns into the blocks. Each trial was filmed in slow motion so that the path of the bullet, shattering of bone, and shock waves could be analyzed in detail.
