Nope - don't worry about it at all. If I was worried about a bronze brush hurting my barrel...I wouldn't shoot it. I think barrels [particularly pistols] are far more durable than people believe.
It really is just curiosity. Cleaning agents get a lot of copy, but the actual process - not nearly as much.
Also, how much of your patch is hitting the land/grooves is very dependent on the size of the jag and the thickness/material of your patch.
