OK someone needs to teach me on what JB compound is used for what. So the cleaning compound has no abrasives and is only for cleaning. The polishing has micro-fine abrasives and will help polish up everything, is that correct?
FWIW... I am hesitant to use the Non-Embedding Bore cleaning Compound, I would NOT use it alone, preferring to add the Kroil, as an additional "lubricant" / "cushion"
I understand JB / Brownells says "it has hurt an inch of rifling yet"... but... something in the back of my mind makes me wonder, if it can clean the fouling so readily, it must have a certain level of moderate abrasive qualities. ( Note the word "compound" )
That said... it has been produced and used since the '60s... and if it was soooo bad, I honestly don't think it would still be on the market, at the very least, there would be all sorts of warnings concerning its use.
And, I have fired some of my best groups of my life, after cleaning the rifles bores with JB Bore Brite ( the Polish ) , Kroil, VFG pellets, and the bore guides.
So, that helped convince me the stuff is working well.
J-B NON-EMBEDDING BORE CLEANING COMPOUND
Quote from the Brownells page
" A unique combination of ingredients and a one-of-kind, multi-step mixing process give J-B its special characteristics. They work together to cushion the abrasive action; the soft paste liquifies as you use it, then wipes out of the bore easily. The non-embedding feature means there’s no abrasive residue left behind which might keep "cutting" after you’ve finished cleaning. "
J-B BORE BRIGHT
Another quote from the Brownells page
" A micro-fine bore cleaning and finishing compound that works as both a cleaner and a final polish to help keep barrels free of fouling and shooting their absolute best. Regular use gives your barrel a mirror-like finish that helps prevent the build-up of accuracy robbing copper fouling, plus greatly reduces cleaning effort. Clean your barrel as you normally would, then after cleaning with J-B Compound, follow with J-B Bore Bright to achieve a super clean, final polish. At the range, regular use of J-B Bore Bright between strings of fire minimizes the accumulation of jacket fouling to help maintain consistent accuracy. As a bore cleaner, the soft, oil-paste formula liquefies as you use it to quickly remove fouling, copper, lead, and powder residue in rifles and handguns, plus plastic deposits in shotgun bores. Because J-B Bore Bright is absolutely non-embedding it wipes easily from the barrel with a dry patch. You never need to worry about Bore Bright harming your barrel. "

So , I am comfortable using the JB Bore Bright , Kroil, and VFG pellets... and a bore guide. It has cleaned my fouled bores enough that I don't consider the "Cleaning Compound" needed.
The VFG pellets really do get into edges of the lands and grooves better then a traditional jag and patch. You can readily adjust the snug fit into the bore by threading the pellets tighter or looser on the cleaning rod threaded adapter.
I am a firm believer in bore guides as well... and inserting the cleaning rod from the chamber end only.
Brownells has a few videos about the Cleaning Compound , Kroil and even with the VFG pellets... search Google for JB Compound... and / or JB Bore Brite
.
Again, while this combo works for me.. YMMV.
And I have never just used the JB alone... I think the Kroil is a important element to the equation.
The time it takes to clean barrels is dramatically less for me.
Seeing how you have ample photos, you are in a great position to see how well it can work.
I looked for photos "before and after" but don't have any at the office.
If you decide to proceed with the JB , Kroil, VFG pellets... please let me know your results.
