I have read some articles where they talk about chanber-ringing but never once define the term. The way they were talking it sounded bad and, if so, how does one guard against it? reindeer

    Perhaps you are referring to the famous "crud ring" that forms a little bit in front of the bullet when shooting 777.

    this happens when reloading older straight walled cartriges (.38/55, ect.) with light loads of smokless power and using synthetic filber fillers (k-poc, dacron, ect.). on firing the filler is compressed and heated and turns into a semi liquid and puts hydralic pressure on the base of the bullet (which doesn't want to move), this results it side pressure on the case wall (and chamber) and can leave a 'ring' in the chamber at the bullet base. this is not good[xx(]

    "Mike, thanks. Is the ring crud or is permanent damage to the chamber?"...this is pernanet damage (like a ringed bore). the single shot exchange had a very good right up on this a bunch of years ago with pix's of a nice stevens that had to have fired cases rodded out. The ring always is at the bullet base, inside the case.
