What's your thoughts on using bore pastes like Iosso and JB for barrel cleaning and polishing? Think it has any detrimental affects on the bore? I hear alot of guys talking about it and both sides have good arguments as to why they do or don't do it.
Opinions on bore pastes?

Here is a list of "using jb bore paste" videos, I use it but probably not enough, I've never seen any negative effect to using it.
What paste do you prefer?

Iosso and Hoppes is pretty much what I use. Sweets 13 tells me the copper is gone as a final check. JB works but not as fast.I read for years these will make the bore too smooth and make copper build quicker, I have not found this to be true. My 30br barrel with north of 7000 rds is spotless. Interesting to see how much metal is gone in the first 10 inches but the rest of the barrel is flawless looking and it still shoots very good.Lot of urban myths out there. Bore scope tells the truth if you learn what your actually seeing.

I use both JB Bore Cleaner (blue label) and JB Bore Bright (red label). If there's some hard carbon in front of the neck in the chamber, I'll get after it with the Bore Bright (red label) on a one size bigger bronze brush. Both break down pretty quickly...which is a good thing.
To me, the Bore Bright is virtually identical to Iosso for aggressiveness.

Al, is this the particular "Bore Bright" you are speaking of?

"abrasives" contain anywhere from 1 micron to 5 Micron Al Oxide. 5 Micron Al oxide is a main ingredient of what is used to lap barrels, so be careful with what you use and how you use it.
I use these depending on severity:
JB
Iosso paste
Flitz Bore Cleaner
Thurro Clean-new kid on the block for me
Methods of use
Patches
patch on a worn bronze bristle brush
used directly on plastic brush from Montana Extreme or Iosso
the very, very worst of cases on a worn bronze bristle brush, usually on a barrel that has never been cleaned
Fine Bronze wool wound in the bristles of a WORN bronze bristle brush or Plastic brush
The finest Pro Shot and Dewey bronze bristle brushes are used for 60 strokes, a stroke defined as one pass forward and one pass to the rear. At 60 strokes that brush is saved for use later on with some of the methods above. Changing bronze bristle brushes at the 60 stroke interval is your first line of defense in keeping HARD carbon out of your barrel. May God have mercy on your Soul if you just use patches to clean with.
With all the above, I am trying to learn a better way. I really hate cleaning gun barrels, but is a necessary evil to keep the accuracy that I like.
Using a Bore scope to examine your bore with after cleaning is a major step forward in your learning curve, and I place it in the same league as learning to use a wind flag in your group shooting.
It would be darn interesting to hear some guys that shoot 1000 yd benchrest with some of those large magnum cases explain how they clean!

No...that's a Remington product. Hard pass on that or Rem Oil/Rem Clean.Al, is this the particular "Bore Bright" you are speaking of?

The JB Bore Bright is the red compound and the standard JB Bore Cleaner/Bore Paste is the greyish-brownish.
Hope this helps. -Al

When, if ever, would you use the JB Bore Bright as opposed to the regular JB Bore Cleaner?

Only if there was a hard carbon buildup that 'standard' JB (the blue label) struggled to get out. On a barrel where that's regularly addressed, JB 'Blue Label' is always my go-to.
On a recent used 30BR, I don't think the area of the chamber ahead of where the case neck stopped (aka: the neck gap) had ever been cleaned. I killed several .338 brushes over the course of a couple days getting that diamond hard stuff out. It was a good time to try some of the 'wonder chemicals' marketed to magicaly dissolve hard carbon and see if they could do anything, though. They did not.
In the end, JB got the job done. I'm sure Iosso would have done a fine job, too.

Al, thank you for your input!
Al, you and Butch are the only two guys I have ever seen on this board mention the JB Bore Bright, and I will order some at the conclusion of this message. Thank You!

I use the chameleon gel from bor-tech. Not as harsh but does cut through the carbon.

It's not going ot do anything to the bore except clean it. Try chucking up a piece of mild steel in a drill and spinning it in a patch full of the stuff for a few minutes. You won't be able to measure any metal removal at all (I tried it). It's good stuff. Do be aware that they will never come out clean - even pristine barrels will turn the patch black when you use JB (the brown stuff, I'm not sure about the red one).
A smooth surface, is different than the edge of the lands. A corner sands much easier than a flat surface. If your rifling is sharp ? That edge is the first thing to go.

It doesn't work telling them. They are convinced that car polish will remove steel from the bore of their barrel. And nothing you can say to them will make them change their minds.
I tested all of the abrasives my favorite by far is Flitz barrel cleaner. And it absolutely positively can't hurt your barrel no matter what anyone says.

I just cleaned up a 30br for a long time IBS score shooter who is done due to health reasons. When I showed him his bore he was flabbergasted. Claims he religiously follwed what a big name gun builder and barrel maker told him to do. It took me two weeks of Iosso and soaking with Hoppes/ kroil to get from 90% black to 5 % black. I have him soaking it 4 days between dry patches to finish it up, he is amazed that he still gets black streaks after patching. For 20 years he thought he was getting his barrels clean. So question is, if you don't have enough of a carbon ring to affect accuracy does it matter? I don't know the answer but I sure don't think a hard carbon coated barrel improves accuracy or enhances barrel life. The fellow he sold is PPC to is still cleaning after 2 weeks.
