JB Bore bright ?

[LHSmith]

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.

Not a Kroil fan for firearms. Check the top of the can after using awhile and it's a gummy mess- I don't want that stuff in my gun. When I used it in the bores of comp. rifles, every barrel required multiple foulers. Lastly, it reeks to high heaven.

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.

great info! thank you-

OP-

Been there are done that with a NIB CZ 452 in .22lr. Sixty some odd patches with regular bore cleaner, not JB anything. I was set straight on a rimfire forum.

 

[SSL]

Yeah, it does smell but I love it for leading issues. Since I follow up with cleaner and actual firearms oil I don't have a problem with it gumming anything.

Well it appears I had some steel left in the barrel of my Sako 75 22-250 after my JB scrubbing.
XBR 8208 35.0g. 52g Berg FB HP Varm.

I rub the JB bore paste into a patch then add a couple drops of Kroil whenever I use it. Short stroke the first 4-6" of the bore then push the patch on through. Clean the residual out with brake kleen.
I hope this helps,

The OP is writing of JB-Bright, while some are advising or speaking to JB Cleaner.
There is a big difference between JB Bore Bright and JB Bore Cleaner.

I’ve used JB bore cleaner but not bore bright. What’s the difference? Is bore bright less agressive?

The Bore Bright is much more aggressive.

 

[CT10ring]

The Bore Bright is much more aggressive.

the bore bright seems to be like a red polishing rouge. I'd say they are 2 different products.

 

[Nature Boy]

I’ve read hear and other places that polishing the bore can cause it to copper foul more than it would if you didn’t polish it.

If that’s correct, what would be the purpose for using JB bore bright?

about a year go I tested most of the bore cleaners and oils on the market. My findings were exactly as printed in the mentioned article except that I’d add that there is powder fouling which is often mistaken for carbon. Just yesterday I cleaned an old 223 barrel which I had previously cleaned and thought was clean because clean patches came out. Upon scoping the bore I found heavy carbon fouling in the grooves. I used kroil, bore tech carbon remover c4, and even Techron. Bore tech c4 did removed a small amount and the others did absolutely nothing. I did not use slips carbon killer as I knew it worked well. In the end, I used jb bore compound and it still took 100 strokes to remove the carbon. My normal cleaning regimen is bore tech eliminator, scope. If carbon is still present, slip carbon killer and soak followed by brushing. If carbon is still present, jb bore compound or bore bribe depending on the level of carbon. Lastly, slip gun lubes are the best bar none. I am not employed or sponsored by any company. The only slip product that disappointed me was the copper cutter. It just didn’t work for me.

Horse hockey. I have a number of highly polished barrels from several makers and after much shooting there is never more than a trace and I mean a small trace of copper and that is removed by 1 patch of eliminator and a few strokes of the rod. On the other end of it, I have a savage factory barrel with a lot of tooling marks that copper fouls in 2 shots

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

Please, Please, Please!!! Do Not, use any abrasive on any brush, it will damage the barrel, we've seen a bunch of it.
Also if you're going to use it, we prefer you use JB Bore Paste, not the Bore Bright, and ONLY on a patch, always followed with a regular cleaning to make sure the abrasive completely removed.
The brush does not follow the twist and skips over the lands cutting grooves in them. We've had many barrels with this damage sent to us for inspection.
I even wrecked the finest barrel i ever had by using an abrasive on a brush(before i came to work here), took out .0005" on 10" of breech area and had cut marks on the lands. That's the barrel i shot the .1426 100 yd LV World Record with. Please don't do it to yours.

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

The black probably the grease in the JB breaking down from the pressure.

Mark,

Are you referring to bronze brushes ? I say that because the Iosso brush (nylon) is marketed for use straight with the paste (no mention of wrapping a patch around it). I have read a lengthy post on another site about this.

Hey Martin,
That was with a nylon brush, and all the damaged barrels sent to us for inspection also used nylon brushes.
I use the Iosso brushes with Wipe Out/Patch Out and really like them, they hold up very well, but i have stopped all together using any abrasive on a brush, only a patch and even then sparingly.

Listen to Mark!!!!!

This what happens when you use a brush and an abrasive type cleaner! Look at the attached picture!

Barrel started having accuracy issues at 100 rounds. The picture is at 800 rounds. 7mm barrel for a Fclass rifle. The barrel physically got .002" polished out of the bore (tops of the lands) and .0015" out of the groove! The gouges/drag marks are from the brush and the abrasive. The bristles cannot completely follow the grooves/rifling. Some bristles will skip/drag over the tops of the lands. No way around it.

So that 7mm barrel which when new was basically .277" x .284" for the bore and groove...it now measures .279" x .2855".

Also we got a .260AI barrel (Fclass gun in the office here) only 110 rounds on it and the gouges are already starting to show. The shooter already polished .001" out of the bore. Using a brush and Witch's Brew.

@FrankG and@Mark Buettgen Thanks for taking the time & effort to post all this great info.
Also great input in the firecracking vs barrel steel thread.

Any thoughts on those VFG felt pellets with abrasive on them? Or with just solvent on them, for that matter.

I think you are suggesting do not use brushes, just use patches, is that correct?
