Yes, indeed. Good point. The newer brushes are nylon with coated "Springy wire" bodies. (Unlike the old ones that were bare metal and could scratch.) The new ones work well. I also went to the sporting goods store and got cleaning kits for rifles and shotguns. Those work well for the straight bits. I sometimes make my own swabs from those plastic cable ties used by electricians along with cleaning patches from the gun cleaning kits.
