Oh yeah, almost forgot...
Everytime you fire your rifle you cause bore wear. Every time. Cleaning the bore between firings slows this process dramatically, but if you want to wear out a centerfire rifle barrel quickly, just keep shooting it without cleaning. The guilding metal coating on typical bullets (soft like brass or aluminum) in combination with carbon particles--plus heat as one poster here has pointed out--cause bore wear, just like any other abrasive backed by metal run back and forth through the bore. Of course there's no human hand shoving that bullet back and forth after the round is touched off so the wear is generally consistent the length of the bore--but it is wear, nonetheless.
