Military switching to "green" bullets (Military.com)

Still need some sort of fuel for the combustion, and I would think that gel would have a hard time compressing to 300psi...could be wrong. It can't be just air, or there would be no need for big oil.

Is is some sort of chemical reaction with the gel? Is the same thing happening in flesh/organic tissue? I would think you would see some sort of cauterizing in the permanent wound cavity.

This phenomenon was discussed some years ago, perhaps in a different forum. My recollection -- which may or may not be accurate, so take it FWIW -- is that it was explained thusly:

The test medium is not ordnance gelatin, which is yellow and translucent, not clear and transparent. The chemical composition of the gel substitute is what fuels the brief combustion.
