Every man has his own methods, so don't let me criticize...
But I would say if you are scrubbing your bore hard enough to make scrapes from a cleaning rod a concern, you're probably over doing it. Naturally, the folks who sell bore guides would strongly disagree with me there, and I would expect them to.
Folks who sell solvents and patches have an understandably exaggerated idea of how much solvent and how many patches it takes to clean a barrel adequately.
Keep your cleaning rod clean, with a very light coat of oil on it. It won't pick up enough dirt to become abrasive. Run one patch heavily soaked with a decent solvent through to get the majority of the powder fouling out. Remember that as the solvent oozes from the patch, it will "carry" the rod across any portion of the throat that it might touch, similar to the way the hydrodynamic film of motor oil prevents your rings from abrading against the cylinder walls in your engine. If you scrub the rod hard against the side of the throat, you can of course break through this film momentarily--but I doubt you could do significant damage unless you deliberately set about to do such.
Then run a brush through, end to end, one time, and patch it out again. Leave some mild solvent (Hoppes 9, Kroil) in the bore to soak with the rifle's barrel level. After 24 hours (or more if you have time) run another solvent soaked patch through, chamber to muzzle (if possible) and switch the patch for a clean, dry one at the muzzle and pull it back through.
Resist every temptation to search for reddish "copper wash" in the lands. It'll be there. It's a barrel.
If heavy copper does become a problem which routine cleaining with Hoppes doesn't moderate, you have a rough bore and it will require a copper solvent. Keep in mind, though, that rough bores might scratch up your cleaning rod, but I think Sinclairs makes some bore guides which should protect your cleaning rod in these instances. /ubbthreads/images/graemlins/tongue.gif
I can't see where solvent running into the action of any rifle I've ever owned has been a problem. Hoppes number 9 is very mild, and wouldn't hurt anything if it did. You'd have to glob one HUGE amount of solvent on a patch to create enough flow from the chamber to then run into the magazine well and become a problem. Hoppes number 9 isn't a bad trigger lubricant if you happen to drip some in that area. /ubbthreads/images/graemlins/smile.gif
I'm not saying my way is best. I'm just saying this has worked very well for me for a very long time. I've yet to have a barrel rust, and I've yet to have one degrade so much in accuracy that it required more cleaning or more equipment that mentioned above.
