Jon, two suggestions:
First is that I would never recommend spraying any sort of cleaner or lube in close proximity to unprotected lenses (scope). At least some scope covers should be used or if none are available some plastic wrap will do.
Second is a question - why not remove the firing pin assembly prior to spraying down the action internals? Give that a shot of the cleaner as well.
Nice videos though. If shooting BH209 powder, that breech plug is probably going to require a bit more than you show here.
