Tend to agree with this.
I'ld just choot'it!
FYI: You mentioned the goal of firing a 1st bullet on a clean dry bore.
Some very knowledgeable folks prefer to fire their first bullet on a lightly lubed bore, after a thorough bore cleaning. Kirby Allen and David Tubb being two of them. They'll run a low viscosity oiled patch through their bores after a thorough cleaning. They believe the lubed bore reduces bore abrasion and wear and tear compared to firing a 1st bullet on a squeaky clean, dry, non-lubed bore. After the 1st bullet fired, some carbon residue is deposited on the bore walls which helps reduce bullet abrasion on following shots. Just what I've read over the years...
Just don't load the bore with axle grease. Use a light coating of low viscosity lubricant.
