After 40+ years of cleaning my own and friends guns, I have come to really appreciate using the best tools available to perform care and maintenance on my firearms. I'm sure all of us at one time or another have stopped at the local big box store and grabbed whatever cleaning supplies were available on the shelf. Those days are long behind us. Thanks in part to the internet and companies spending the time and money to create some of the finest cleaning supplies on the market today. Tipton's Best Bore Brush Set is one of those products I'm speaking about. With 8-24 threading, they fit into most of the newer cleaning rods, the brushes are made to exacting standards and it takes less time down the barrel to loosen any and all materials left from our day in the woods or at the range. I highly recommend purchasing a Tipton's Best Bore Brush Set and attach them to the Tipton Carbon Fiber Cleaning Rods for a great cleaning experience the next time you are at your bench. I did use a Sharpie to write on the outside of the clear casing what caliber each brush was for. (It's easier than looking where you left your cheater glasses this time.)
This is all I did to find the correct size bore brush without having to look at the back of the packaging.
