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

There's no way to tell the type of bullet used based on breechface impressions. Generally premium ammunition will have a laquer-sealed primer and nickel-plated casings.
Are you trying to determine if the casings in question were "hot" handloads?
Every handgun has its own unique breech imprintâ–¬Glocks have a rather distinctive breechface marking
