Brush Research 08309 Revolver Chamber Flex-Hone, Silicon Carbide, 800 Grit, For 9mm Pistols (Pack of 1)

It cleaned and smooth the revolver cylinders really nice.

I have two of these. One in 357 and one in 44. I had been shooting 44 Specials in a 44 Mag revolver and 38 specials in a 357 Mag revolver. After a period of while, a crust will build up in the chamber just in front of the shorter cartridge. This crust is very difficult to remove with normal cleaning methods. These clean out this crust slick as a whistle. Not to mention polishing the chamber to facilitate smooth ejection of fired rounds. A must have item for Cowboy Action shooting.

Works well. I have a 454 Alaskan with tight cylinder chambers. No scrubbing with a bore brush would help. A few passes with this cleaned everything up. Make sure you use oil. If I were to do it again I'd get both grits.

I used this hone to clean up a rough finished chamber that was causing issues when dirty. I tried fixing the problem with just polishing but it was not enough. Since using the home and then polishing the chamber I’ve had zero issues.

I rated this item a 5 because it works great! The only negative is the short length of the shank. It makes it difficult to hone longer barrels. I had to purchase a drill bit extension to do my barrel.

good

I used the on a Ruger Vacauro 45 Long Colt, now the empty rounds drop out without using the ejector.

Honed out the cylinder on my 357. Make sure you use honing oil.
