JB Bore bright ?

[CT10ring]

I decided to run a patch using JB Bore Bright thru my previously "cleaned" Sako 22-250 chromoly factory bbl while I was checking resized brass dimensions.

To my surprise, the clean barrel looked like this...

So I then cleaned with brushes, patches using Butch's -my standard until clean. Then ran some more JB Bore bright thru, expecting to see a pretty clean patch. Instead- more patches that were blackish.

I'd like to think the rifling looks clearer peering down the bore after. Not sure.

I used to shoot V Max moly coated quite a bit years back.

Thoughts?

I have other cut rifled SS barrels and they clean up quite quickly.

any info appreciated. I did a search on this site & read a few remarks.

Bore bright is an abrasive compound. It will continue to remove metal from your barrel as long as you keep using it.
Now that you have polished the barrel, follow up with your normal cleaning process to remove the residual Bore Bright.

I like to use Kroil to flush out the residual abrasive compound, it seems to work well for me.

Every patch you run thru will look like that- even if you rub on the outside. Its a metal polish- thats the black

Did you read and follow the instructions on the bottle? Both JB bore paste and JB borebrite will ALWAYS give you a black patch no matter how clean the barrel is. It is normal for the patches to look like that. dedogs

Unless I am misreading your sequence, patches with JB WILL be black due to the breaking down of the already dark paste. Following up with a regular cleaner should get rid of most of it, but I have had stainless steel revolver barrels produce darkened patches even when mirror clean.
JB used right can save a good barrel. I once bought a Ruger #1B in .22/250 that the previous owner was honest enough to tell me that the barrel was shot out. 4" groups are considered the best it could do. Just to be sure, I spent quite a bit of time cleaning with copper cleaners and JB. It now shoots 52-grain Amax bullets into .3" groups. This from a rifle made in the 70s that had been used for prairie dog shooting.

thanks gents. exactly what I thought. I could do 1000 passes and it would always be black...and no cleaner.

I have used simichrome polish (not on guns) and it looks exactly the same. clean metal & black cloth...

Yes, I read the directions on label-- states to make 40-60 passes (!).

I never pull brush or patch back down barrel, so I used 20 or so patches. I will say that yes the rifling is clearer. I will use this sparingly in the future though. This rifle shoot great & I want it to continue.

I have never used Kroil, will try it in the future.

Until you use a borescope to look at your bore, you really don't know what you have.

Let us know how it shoots after the Bore Bright.

Pulling an UNDERSIZED nylon brush back down a barrel wont hurt a thing, and in fact can help smooth things better. If you are going to continue using this product, I strongly suggest you start with Kroil and JB BORE-PASTE followed by the Bore-brite. Works very well. I have had the same experiences as SSL. dedogs

doesnt the directions say to "short stroke" it? making one way passes will never get it clean. brushes are different than patches- stroke it til youre satisfied.

agreed, I am only guessing if it looks better... and the lands are (never were) not as defined as say, a krieger or rock.

you are correct. I did not follow the instructions really, just improvised. I will try an undersized brush after shooting this one (test loads).

thx-

You might enjoy this. Of course shortly after I read it, I had a Hawkeye to assist me. The pictures at the end were very interesting to me.

Every bench should have Kroil! Even works on barrel leading. Just don't allow it to get to action screws and such. It penetrates so well it can allow them to loosen.

I personally like KG-1 for carbon fouling and KG-12 for copper.

I'm not sure that I want that much info. I just shelled out for an annealer & a liquid media tumbler. The rifles are the lea$t of this...

Put it on your Christmas list, Along with a Porsche GT3. You'll get the Borescope

You'll often see things that will make you sick. Rather than the bore scope, get the GT3
