Higher energy living tissue SRAP impacts will also result in less probability for over penetration.
With respect to increased velocity SRAP bullet performance variables when impacting ballistic gelatin, there is no specific data. The 9mm CQB SRAP bullets which dramatically fragment in living tissue do not demonstrate either bullet core expansion or fragmentation when penetrating ballistic gelatin. I would guess that unlike conventional hollow point bullet designs, higher velocities achievable from functional duty weapons would not alter the bullet characteristics of those specific rounds.

Thanks very much, Stan. Seems to me there has to be some characteristic in ballistic gelatin that responds very differently than live tissue at these high velocities. Query whether there is a significant difference in terminal effects of lower velocity rounds in gelatin and live tissue as there is with the high-velocity LeMas rounds -- do we know this already? If not, I think it would be useful for someone (ideally swatsurgeon) to perform the same live tissue analysis on lower velocity rounds to see whether there also is difference between terminal effects observed in gelatin vs. live tissue.
Of course, I am not an expert. I hope no one is bothered by my lay analysis.
