Patch Out: Recommended

If you can reverse the stroke with a bronze bristle brush, more than likely it is worn out and you are only touching the tops of the lands, not the grooves. The dia of the brush needs to be slightly bigger than the bore die so the bristle will bow. The Bow in the bristle is what does the scrubbing. By the time the bristles wear to a point to where they are straight, the brush is not doing much scrubbing.

Stainless brushes are hard, bristles resist bowing, thus the cause of them ruining barrels.

Okay. I see your point there. Thanks for that! So you agree that reversing the bronze brush does no harm except to the brush and is ineffectual for stubborn throat carbon. However, a steel brush, used correctly & carefully is much more efficacious?

So you know there is/has been issues.

Please elaborate into the metallurgical foundation for this conclusion. Not trying to prove right or wrong, just really interested about your theory that the non-metal brushes are revealing an insidious source of damage.

Not theory. There are/was photos out there. The shooter I know took a section out of his barrel for hard evidence. He also put it in a lathe to see how it machined up like butter was the comment. There had been discussion on another forum which he joined to find out more. When he put up his issue and evidence he got banned.
His barrel was the same make as the one where the cleaning rod got the blame.

Banned for taking a scientific approach to help his fellow shooters? By simply presenting evidence about cleaning methods???? WOW

Pistol shooters have been scrubbing lead out of blue and SS barrels for more than 30 years that I know about without issues using SS brushes because that was all that worked me included.
I agree about the wear, SS brushes do wear. I don't use the coil type brush I can see they will cause issues. Bristles are ok.

I would *never ever* use steel on steel in my barrels.

Did I mention "ever?"

You are NUTS if you use a Stainless steel brush in a quality rifle barrel.

I have seen over size bronze bristle brushes leave scratches in world class rifle barrels.

If a brush of any sort scratches a barrel it is a crap barrel wrong steel.

Does Patchout suggest to use a nylon or brass brush?

Wow.... detect a lot of "assumption verses fact" in several replies.....
Will suggest this: no matter one way or the other, if you do not have first hand experience, your lacking in fact. If replying with assumption, state as doing so. Anything else is just righteous bullsh^t and corruption to legitimate information and discussion.

Does Patchout suggest to use a nylon or brass brush?

From the Sharpshoot-R website about Patch-Out

“While this product has been designed to be totally brushless, admittedly there are those who still wish to use a brush. If the user will take two strokes through the bore with a nylon brush “PATCH-OUT” ™ will produce a luxurious thick lather. Allow it to set as per original instructions for faster results. “

Not to get too far off on this original post, but for those that are using JB or Iosso in your cleaning process...are you using either of the 2 applied to a brush, applied to a patch on a jag or applied to a patch wrapped around a slightly worn brush? Thanks

Brownell's description of there SS Bore Brushes:

"Stainless Steel Bore Brush - For severely leaded, fouled or rusted bores, the aggressive cleaning action of a stainless steel brush can help get them clean. However, the aggressive action accelerates wear, and regular use can shorten barrel life."

I exclusively shoot Bartlein SS 5Rs and admit to subscribing to the magical anecdotes of the elders; I am guilty of much speculation and am looking into seeking professional help! All joking aside, these discussions (since they should exist to further our sport) must occur from cited, rigorously tested, objective & unbiased information. Thank you for calling out my straw man. Cheers.
