… JB Bore Paste.
I have used origional JB bore cleaning compound for some time now and just tried the JB “Bore Bright” paste. The bore bright is a finer paste that puts a mirror finish to the bore to be used after JB Bore Paste.
I have recently been experimenting with Bore Tech C4 carbon remover, and it does work quite effectively, but it does not completely remove all the hard stubborn carbon in the throat. The rest of the bore is nearly clean of carbon, although you can still see the light grey appearance of some remaining carbon all down the bore. Here is my DCRA 7.62 after cleaning with C4, throat is still quite dark. ![]() About 2 inches forward of the throat: ![]() Now after 20 strokes of the regular JB Bore Paste, the throat and about 2 inches forward of the throat: ![]() ![]() Now, after 40 strokes with the JB Bore Bright ![]() ![]() Might be hard to tell in these photos, but the bore looks significantly brighter after using the “bore bright”. I expect the mirror finish will result in less fouling too. For cleaning with JB, use a worn bronze brush and wrap a 1.5 x 3 inch patch diagonally around the brush with JB worked into the patch first. I wet the bore first with Kroil on a patch, and clean out the JB with Kroil on a patch. |

I may well do that on my Lithy SMLE. The bore is clean as a whistle, & rifling looks brand new, but still dark when viewed with the bore-scope.

Geoff, maybe you can help me sort this out…
I never used boretech products since I always used Forrest foam to deep clean barrels, i bought eliminator and c4, yesterday I started cleaning my mk2 barrel with eliminator following the instructions on the bottle, all the copper was removed, then did the same thing with c4 and left with muzzle down 24hrs to dissolve everything. Today I restarted cleaning and I found this white gunk on the rifling even after clean patches. JB bore paste and bore bright are coming next week from brownells, since no Italian armory keep those products…. Is it lead or is it carbon in your opinion? It is not pitted or rusted, barrel is like a mirror, you can see shiny grooves under this gunk, but eliminator and c4 can’t remove that….

I’ve not see that when cleaning my rifles. Did you shoot cast lead bullets at some time? The patches turn blue from the copper when using Eliminator, and black from the carbon when using C4.
That bore still looks quite dark in the photo, almost like it was a phosphate finish. It should be bare metal. You might have layers of carbon over copper, I would clean it again with eliminator, repeat until no traces of blue on the patches, then clean with C4. You may need to repeat this a few times. The JB will make short work of what ever is in the bore (copper, carbon and lead) and it will be down to bare metal with just one or two applications. When using JB, use a worn bronze brush, work the JB into a patch on the palm of your hand first then wrap it diagonally around the brush, a 1.5 inch x 3 inch patch works good for this. |

Never shot cast, I did the cleaning two times, and went exactly like you said, the copper removed at first is reappeared after the c4 carbon remover cleaning.
It’s a photo effect matter, the bore is actually bright, but I can’t remove that gunk….. What do you mean by work the jb on the palm of the hand? Did you mean like soaking the patch with jb in to the palm? Sorry for that but sometimes I don’t understand English at 100% Anyway, thank you Geoff, I’ll post an update after the jb treatment |

No worries.
To apply the JB, lay the patch flat in the palm of one hand and use your finger on the other hand with a dab of the JB paste on it, and rub that into the patch. Keep rubbing a bit of JB on your finger then into the patch as necessary. You want to work the JB into the patch to turn it an even gray colour, don’t lay it on thick, just work it into the patch with your finger. Then wrap it around the brush.

I am following this, for when I get going with the JB paste!
Thanks Geoff.

Old Fouling is like a Croissant, layers of one thing with layers of another separating them, but still there. Sometimes you have to dig down many, many layers treating each one as it surfaces, revealing the next problem from below. Then you treat that one. The same as you treated the one above it. It can be a time consuming & frustrating process. You just keep digging down to bedrock (the real bore.). |

Absolutely, this is what happens when bores are neglected. It’s surprising how many don’t clean the bore after every shoot. Even with routine cleaning, fouling accumulates. Some of the hardest to remove was the old cupronickel jacket fouling used prior to WWII.
The danger is that moisture is trapped and pitting slowly works its way into the steel. Even worse if corrosive primers were used, the pitting starts almost immediately. But, based on my borescope inspections, JB will remove all fouling quite effectively. I would not recommend using it for routine cleaning as it is abrasive and does polish the steel. Excessive use will likely lengthen the throat. Every 400 to 500 rounds should be sufficient. This is where a borescope is so useful. |

I got the teslong ntg-100, I’ve seen it’s quite popular here with nice reviews, so I have given it a try.
The photos shows no copper or super hard carbon buildup, all I can see in my humble opinion is light pitting starting just 2” in front of the throat and some hard carbon ring at the throat beginning, grooves are sharp and shiny, the white gunk I believe it is the beginning pitting formation. If it’s so, I’m saving this barrel… I always cleaned the barrel after shooting with CLP and a tight bronze brush and deep cleaned every 200rds with Forrest mil-foam, that dissolves copper and light carbon… Here’s the pics I took starting from throat to muzzle. Interesting fact, at 5” where the center bedding bearing is located the grooves are perfect and mirror finished ![]() ![]() ![]() ![]() ![]() ![]()

Yes, that is pitting. Is this after cleaning with JB?

If you have JB, that should remove the remaining carbon and polish the lands somewhat.
