Any problem with JB Bore Paste?

I had a very dirty/suspect barrel on a Mosin that I used JB on. I took an aluminum cleaning rod, removed the handle and inserted it into my cordless drill. Attached a brass brush and covered it in JB, inserted the whole deal into the barrel with the drill running at slow speed. Did this a few times then cleaned it very thoroughly and came out with a very shootable gun. Good luck with your .223.

I use JB's bore paste per the directions. After you think you have all the powder fouling removed, put some JB's on a patch and work it through the bore. You will be amazed at how much fouling remains. I also use the JB conditioner prior to shooting.
Yes it is abrasive, but mildly so. You don't mention the type of fouling. If it is copper fouling from the bullet jackets, there are much better solvents out there to remove it. I wouldn't expect it to do wonders for a corroded barrel, but good luck.
I have used it. Works well. Follow the directions. It will not harm your barrel. It will not do anything for a corroded barrel. You can use any oil, doesn't have to be JB oil.
If it is copper fouling the only solvent that actually works is KG 12 Copper remover. No debate needed, look at the tests and I have tested it myself.

I use Butch's bore shine for the first scrubbing of the barrel. Then wrap one of the large military style cleaning patches around a worn bore brush. Then annoint the patch with the JB compound and start scrubbing, almost immediately you should see some dark black crud on the patch. Patch out the JB with Butch's bore shine and repeat the process as needed. When done patch out any Jb again and do the patch thing on a worn brush and annoint that patch with JB bore shine.
Inbetween scrubbings with the JB bore shine use the Butch's to patch out all the gunk. When finally done then use Butch's to remove any remaining junk. I usually leave the bore wet with Butch's oil. And dry patch it out before firing. When shooting you are depositing carbon and copper fouling in layers and when cleaning its just the same except you are removing both layers. Frank

Bushmaster at one time recommended it for cleaning the barrel of their match rifles during the break-in process.

I have only used it once or twice and worked just OK. Still needed the LLR for completing the task.
IMHO the Lewis Lead Remover followed by a new bronze bore brush and a good solvent is still the best way to go. For me the LLR is the NUTZ!

I've been using JB for over 30 years. It works well for some things; not so well for others. For getting through the carbon/jacket/carbon/jacket fouling of old milsurp rifles, it's the shizzle. It takes a while to get down to bare steel sometimes, but it does work. For a corroded (pitted) bore, it won't do much. You might be able to firelap down past the worst of the pitting, but that's a whole different subject.
I'd recommend electrolytic rust removal, if that's practical for your application. Google is your friend.

When you are done, and you think you have all the copper fouling out, run a patch with Sweets down the bore and let stand for 10-15 minutes, then a clean patch. If you come out clean, great, if it comes out blue, you aren't done.

All good advice. Sweet's is nasty stuff, don't get it on things that don't need cleaning.
KG Coatings KG12 does a pretty good job, if you wait a bit.
Wipe-Out also does a good job.
The chemical cleaners need time to work. I've watched people patch them in and patch them out immediately - rarely with good results.

Hi, new to the forum,and thought I would start off by giving a recommendation. For years I had used Butchs' Bore Shine and Sweets to get rid of copper and lead fouling on my fire arms. I am now using Bore Tech Eliminator. It is more expensive than the others but I wont use anything else. After cleaning a rifle barrel with Butch's and following up with Sweets until the patches came out clean, I ran a patch with Bore Tech through the barrel and the patch came out bright blue.I continued the cleaning with it and removed the fouling better than anything I have used. It has no smell, and it wont harm the metal in any way. Try it, I dont think you will be disappointed. I got mine from midwayusa.com I am sold on this stuff, and I dont have any interest in the company at all
