Fragmenting bullets versus controlled expanding bullets

[MoeFaux]

Thanks for the article. It has good information.

I did a quick read and scan. Here is a picture of the x-ray they did of a .308 “lead core” bullet into ballistic gel containing a deer humerus.

Doesn’t look like the lead spread out very much even hitting bone.

The study doesn’t provide anything that would dispute my hypothesis that lead does not spread beyond the wound channel. And microscopic lead cannot travel further than visible lead pieces because it has less mass—so how could it physically pass through meat?

Can you point me to a specific passage that would help me understand your position?

I know I'm responding to an old post in an old thread, but thought this detail should be added for consideration. This quote appears several pages after the photo referenced above.

The existence of thousands of single digit micrometer-sized particles, comparable to mammalian erythrocytes [45], challenges the current understanding of the maximum extent that fragments may be distributed in a harvested big game animal. Though it has been shown that lead concentrations are highest in the immediate vicinity of the wound channel [42], bullet fragments have been previously observed up to 45 cm from the bullet pathway [17]. Typically, a big game animal is not instantly incapacitated, and during its final moments, micrometer-sized fragments could feasibly enter the bloodstream and be transported throughout its body. Ingestion of very small lead particles would explain the accumulation of lethal and sub-lethal lead levels in scavengers in cases where no fragments were found in a medical radiograph or biopsy​
