Chet whitebread hands down makes the best bore guide i have seen or used. wonderful concept, and half the price of a nolen. lee
ps i have a lucas guide i can make you a heck of a deal on, if you need one quick.
I would like to add one more thing about my experience with bore guides. A while back i had some carbon issues in one of my ppc barrels so i selected to use some Remington 40x pumice type cleaner. While working my rod back and forth in the bore, i could hear the rod dragging across the throat with grit in the cleaner. It sounded awful!! It really opened my eyes as to how a bore guide needs to work. I feel like you really need a bore guide that centers and supports the rod in the center of the chamber so you dont have any rod drag across the ever so important throat area of the barrel. The Nolen and chet's guides are the only guides that i have used that actually do what they are supposed to do. Im sure there are others out there but i haven't used them. Dont go cheap with a 15$ bore guide. its a waste of time and it will ruin your 500$ barrel. Lee
