How are you getting cleaning solvent on your stocks? Limit the amount of solvents you use to avoid drips and spills. I just use my off hand as the bore guide. I always clean the chamber area when I'm done and even wipe out the area between the lugs and barrel breech to make sure there is no debris or solvent left to gum anything up. Make sure to grease your bolt lugs when finished. There are lots of posts on cleaning and lubing here.
I only use the 3 piece rods on shotguns and have given up using them on rifles. Too many broken threads or bent ones. One piece is the way to go. I doubt you have damaged anything internal. Crowns can be damaged with poor cleaning techniques.
