I've read in previous posts, people taking about using the JB method in their barrels. Could somebody tell me what this is? Where do you get the JB. Thanks
SEWER, I am assuming they are referring to the use of JB Compound to clean or polish up the bores of their rifles. You get JB Compound from Brownell's.

It is a paste containing a very mild, non-imbedding abrasive. You use it on an oiled tight-fitting patch, and it will remove any lead, plastic, or other fouling from your bore. In addition, it will also polish up the steel that the barrel is made from, after removing the crud from the bore.
It will NOT damage the bore. But you have to be careful how much poishing you do to a ML barrel. Don't polish up the bore of a round-ball gun-they shoot better with a slightly rough bore. The patch material alone will smooth up the bore until finally accuracy goes down the tubes. But this takes literally thousands of shots!
