They are referring to bullets that have different abrasives incorporated into the surface that are used to polish the bore of new/rough benchrest rifles. They might help a little bit, but I wouldn't expect much. A barrel with deep pitting is not something that can be polished out with out markedly increasing the bore diameter. They have to be handloaded into your brass, as far as I know. I believe that Brownell sells them, and most likely others. The actual name of them escapes me currently(that happens a lot with me these days).
I guess that I type too slowly!!
