Maybe a short subject for the fireside chat.
When you complete a new build, what methodology do you go through at the range to test the new piece?
Do you plan on shooting a certain number of rounds? What kind?
Are you looking for functionality, reliability, accuracy?
Do you chronograph the shots?
What do you take notes on, if any?
What are your expectations?
What actions do you take when you return from the range?
This is an awesome subject. It is surely on the list as a follow-up to the Top 5 Mistakes: "Operations" editions show.
