JB Bore bright ?

[Capt. Oblivious]

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

I use allot of them and cant imagine they would act any different with Iosso or JB than a patch

Thanks for the advice Mark & Frank.

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

Yep!

I have the JB products and was afraid to use them inside the barrel. They work great on the outsides.

I saw the photo of the patches. I have a picture of a pile of about 50-75 blue/green patches after a cleaning of a CZ 452 years ago after first range session. It didn't dawn on me to use an aluminum or nickel jag instead of the brass one until a friend who actually passed chemistry the first time around in high school told me what the problem was in the false positive results.

I appreciate the input from the barrel makers, and also the guy who resurrected the zombie thread. But now I’m confused. I thought JB Bore Compound was coarser, and Bore Bright was finer. It seems to indicate that right on the labels. They want you to use the Bore Compound (coarse) for the heavier fouling and Bore Bright (fine) on a clean barrel for polishing only. Have I got it wrong?

youre still right.

 

[slancey]

Thank you. So if that’s the case, then why would someone recommend only the coarse version but not the fine one?

By the way, I also have had a borescope for several years and I have never seen any damage to any of my bores after using either of the JB products. The product even has a guarantee on the container that its use will not harm barrels. Has anyone else seen this kind of damage?

Take what you read and research it to find out is the only way to know. You actually only had to read the can and figured it out. As to the damage it only happens with abrasives on nylon brushes (of course some can tear up an anvil with a feather duster)

 

[slancey]

Got it. I only use bronze brushes anyway. Thanks for confirming.

and with abrasives on bronze brushes also.

Why don’t you try flitz on a nylon brush. It works and is non abrasive. Done deal.

 

[SSeal]

If I understand correctly the difference is the hardness of the abrasive not the size of it.

Why don’t you try flitz on a nylon brush. It works and is non abrasive. Done deal.

But flitz is an abrasive and the nylon brush by itself is an abrasive- double whammy.

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.

Check it with a borescope. Without borescoping a barrel, you really can't tell the condition of your barrel. Clean patches are not necessarily an indication of a clean barrel.

It's not always about the grit size. it's more if, and how much/quickly it breaks down.
For example our lapping compounds that we mix are quite coarse, but they break down very quickly and we re-apply often or as needed(feel).
Many of the abrasives out there do not. Also need to be careful with over use of abrasives, getting the bore too smooth as will cause copper issues.
Later, Mark

A nylon brush is abrasive????

 

[Dusty Stevens]

A nylon brush is abrasive????

Yes. Very much so. Look up pictures frank g has posted of barrels that have been sent back in

 

[JMayo]

Very interesting ... However those rivers in the grooves seem really aggressive with no corresponding marks on lans and the edges still show sharpness.
It's So agressive I go "hummm" gotta be something else involved....

But I'm sold on patches only with jb untill barrel is in on its last leg.

ask a fisherman what happens to the prop shaft when fishing line gets wrapped up behind the prop

The fish side of the line always breaks and I lose the fish
