Howdy,

Will it hurt the cylinder walls of my Blackhawk if I use the approppriately sized Hoppes bronze brush (.357 ) attached to a Dremel Tool to clean the cylinder? There is a great deal of buildup within the chambers after firing .38 special wadcutters.

Thanks
Jack

It won't hurt a thing so long as it is a bronze brush and not stainless steel. To clean the body of the chambers a .375 rifle brush driven by power will work much better than a .38/.357 pistol brush. It will not be damaged (the brush) by using it in the throat either.
