I want to slug the barrel of my King Cobra, but I've never done it before. Do you put lube on the slug before you tap it through? Do you lube the barrel?
I am assuming you are slugging the barrel in preparation of shooting cast bullets. If that is the case my thought may go against some. I slug revolver throats and size bullets to that diameter.
I agree with that, but how do you slug the barrel throat? The throats in the cylinder seem fine. A cast bullet will easily pass through without them sizing down. But, I think there may be a problem with a constriction where the barrel fits the frame. I say this because the leading I get it right there at the forcing cone/barrel throat.
You're measuring to three decimal places and if you're doing it right with a tool that measures to four decimal places (micrometer not caliper) so you want to introduce something that will have a film thickness somewhere in the three decimal place range? Let that sink in a minute.
There is no reason to use lube with a pure lead slug in a steel barrel or revolver cylinder.
