Carbon Ring ?

[jelenko]

bronze brush, and stroking it up and back

This means reversing the direction of the bronze brush in the bore? If so, I'm assuming it needs to be a worn brush, yes?

Wow, now that is an eye opener! Turns out I've been concerned about a shadow

Here is a shot using the borescope from the other end...the "carbon ring" I could not remove was just a shadow (I also found other areas in the bore that were also shadows by going the opposite direction):

Another great learning experience for me today too, thanks to this great forum!

Excellent point. I figure cleaning the chamber and bore with the regimen that I follow, I'll never have a carbon ring build up in the leade area:

To me, this is a much better application and use for "weed-whacker" line than its intended purpose. I lathe turned a brass cylinder to 0.200-thousands Ø and then threaded a through hole in it. Ran the weed-whacker line all the way through until it pokes out the other end and then heat the brass cylinder until the line seizes up tight.
After shooting 25 rounds or so, one wet felt cylinder with some EEZOX and back to shooting. Quick, and I haven't had any build-up of any sort of gunk in the leade on any of my .22 rimfires. Can't remember when there was a need to use a bronze brush, and I do peer inside the bore frequently enough to notice anything like that with my Lyman bore scope. I just can't imagine some folks who swear they NEVER clean the bore(s) in their rimfire rifles and don't get that "dreaded" carbon ring.

If only I had a lathe. And knew how to use one. Seems like a fret idea and I like eezox. It does a good job of cleaning and lubing. Maybe a bore snake would work about the same.

Instead of a "bore snake" I'd recommend the Otis pull though system as a better choice. My aversion to bore snakes involves the weave of the material used. That weave will collect and become impregnated with gunk and some of the glass particles involved with the primer mix used to help ignite the primer. As the gunk builds up in the cloth weave, and then pulling the bore snake through the bore over and over again, especially on the shallow rifling of a .22 rimfire bore, I just don't think is a very good idea.
