I do a fair amount of gunshot wound research and I post cases on LinkedIn (mainly for clinical and forensic audiences). In many of my research cases the bullets were either imaged by X-ray or were retrieved at surgery and I got to photograph them.
I’ve noticed a significant variation in the appearances of the bases of these bullets, especially when it comes to how the jacket meets the core at the base of the bullet. I would like to know if there is a standard way of describing these.
Here’s an example of four unfired 9mm bullets:
They have various jacket closing features, from flush, to recessed to plated. Number 2 is a sort of rolled jacket that sits proud of the core.
I have asked this question on other boards and got a variety of answers. The AFTE guys put me onto the CartWinPro team and I got a very helpful reply from Renee Jousma and Marinus Knap. They have an extensive list of descriptions of bullet bases, shapes and jacket closing types. I am not going to post that list here, but you can find it within the CartWinPro program.
So my question is: other than the CartWinPro list, have there been any other attempts to categorise bullet bases styles?
If so, I would like to know about those descriptions so I can use those to describe the bullets in my cases, rather than reinvent the wheel.
