But there is nothing wrong with that method. You have provided photographic evidence that it works. Well done!
Also, if you are going to truly evaluate a bore, you need to cast a soft lead slug, lube the bore lightly, and force this chamber slug into the bore. This involves hammers and brass or steel rod if you are confident in your skills and is NOT for the 'faint of heart'. What you are 'feeling' for is tight or loose spots within the bore. You have to push the slug to and fro in the bore, feeling for abnormalities. It takes a bit of experience to know what feels 'even' and what does not.
But unless you're interested in precision shooting and minimizing copper fouling, then this stuff is of less importance. I've been hangin' around on a benchrest forum and things are 'different' over there. Easy to forget.
Anyhow, best of luck to you Sir!
Again, I hope you get a 'long' straw instead of a 'short' one next time.
