As far as the marks on the shell casings of the .45 WCC and TZZ, would the breechface impressions on the casings be any different if one was a FMJ? My understanding is that the impressions vary on the pressure exerted on the bullet itself as it leaves the chamber-is there anything about a FMJ that would make the breechface impression different?

And do any of you know an expert who would be willing to email me privately about these questions?

I am an attorney preparing for trial.
