It was just after they'd started using .40 S&W, but it sounded like they were still influenced by the success of the older .357 Magnum and its performance. As I recall, their FTU people weren't publishing stuff for outside dissemination like the FBI, and at the same time they didn't necessarily see their needs as being the same when it came to "ballistic performance" as being interpreted within the context of gel testing.
No link. No archived report. Sorry.
I'm not the only LE firearms instructor from that time period, though, so someone else who visits the site might have further info.
