I saw a new cleaning rod/system marketed online by Remington,
www.Remington.com . It's called the SQEE-GE(check correct title).
This new gun care product removes the lead, gunpowder, gunk etc in one pass. The website has a video clip. It works on nearly every caliber from .22LR to 12ga.
I had a few Hoppes BoreSnakes. They did ok & cleaned the firearm barrels with no problems. I use Ballistol & CLPs like LPX, Weaponshield & Slip2000 mostly.
Brownells,
www.brownells.com is a highly rated source for gunsmithing & cleaning items.
