Iosso Eliminator blue nylon brushes

I have some of these in addition to black nylon and metal brushes. I’ll give them a try this weekend in a barrel that normally takes 2-4 passes with the metal or 20ish with the nylon and report back.
 
They are a nylon brush of a different color. Would you wax a car with a scrub brush? Clean a window with a broom? Why would you try to polish the carbon from a barrel with a brush?
 
Another great use of the blue brush is to chuck it up in a cordless drill and spin it through each case neck prior to charging and seating. I've found this to be a worthwhile step in consistent seating pressure.

Dusty, - Yes they are a different color but that's not all they are. - Now, I'm not here to start a debate on carbon cleaning as there's plenty of threads already on here on that topic. - And I'm not here to say Iosso blue bristle bore brushes are a replacement for bronze bristle Dewey or Pro-Shot bore brushes. - They are like a nylon bristle brush on steroids, quite stout and if used with Iosso paste can actually get some real cleaning done if needed.

Have you ever used them or inspected them?
They give a whole nother meaning to plastic/nylon brushes. They are definitely not soft, like others are.

I use them every time to Iosso the barrel (just as the Iosso instructions says to do), which for me is after I've pushed the excess fouling out with bronze brushes and solvent. They get the carbon and layer out effectively for me.

Yes ive used them. I have a few pkgs of them and the black ones too. I know theyre stiffer but also wonder how an abrasive stays on the tip of a brush- still like cleaning a glass window with a broom. Iosso on a patch is my method and it works very well. I dont have to carry 3 rods or switch brushes. Simplify my life is my motto. Butchs, pro shot patches, bulk bronze brushes, iosso, flitz and the 2 jb’s will clean any barrel at any point in its life and do it very quickly.
 
Boretech nylon brushes are tighter fitting than most.

However I still insist on using bronze brushes for carbon removal since I believe that the mechanical action of the bronze brush helps prevent formation of a carbon ring. But what do I know, I'm not an 'expert.'
 
I bought a few to try. The .243 brush is very tight but usable. The .223 brush is so tight I gave up trying to use it due to rod flexing.

Same thing here. Got them initially for my 308... worked well. Got some for my 6.5, and my 223. The 6.5 brushes worked fine, but the 22 cal ones go in about a half inch and then hard stop. Devil of a time getting them back *out*.... :(
 
Montana Extreme makes a heck of a plastic brush also, and when used with their Copper cream, the barrel gets clean. If you have a rough barrel to clean and run out of ISSO or JB, you should give the Copper Cream a try, it is much easier to use and very effective.

The .22 caliber blue Iosso brush wrapped with a cloth patch & Iosso paste as Alex pointed out does a good job of applying Iosso paste to the bore of a 6mm. - That's where I use the 22 caliber ones.
 
Question:
When using brushes in your bore, do you use a bore guide, and in the case of a bolt gun, do you pull the guide partially out of position after the brush pops out the end of the guide, in order to scrub the neck/freebore/throat area? Just wondering if leaving the guide in it’s normal position, without backing it out leaves uncleaned areas. Thanks
 
Brushes should go one direction only, from front to back or from back to front. Never push a brush partially in the bore and try to reverse the direction. Of course, this refers to a brush that is bore size, not under size brushes.

I put the Montana extreme copper cream on a patch, using a tight punch style jag, and work back and forth in the area of the throat If I have a problem on some gun that has been abused.

For carbon build up in the end of the neck, I use an over size brush and turn it by hand on the rod.

Montana Copper cream on patches is an amazingly effective way to clean, and very easy to clean behind unlike using Isso or Jb.
