When using this paste, when do you stop? When the patches are no longer black, I assume? I just bought some and have never used it before. I first used Gunslick foaming bore cleaner and then the JB cleaner. I followed the directions and did three different applications.

I don't know if I should do more or not. Also is the Cleaning compound a slight abrasive, so it could smooth out my rifle bore?

Corey,

JB's is quite abrasive and can damage the bore, rounding off the edges of the rifling. A little goes a long way so be careful and don't over do it.
It is a great product for those stubborn spots.

I don't think you realistically could have damaged your bore with only three uses of the compound. JB is "quite" abrasive as far as bore cleaners go. That doesn't mean that you could wear your rifleing smooth in your lifetime. In my opinion you should only use the bore cleaner to remove moly, which solvents will not. There are many other products out there that will get out your copper fouling and powder that are not as hard on your barrel. Hoppes #9 bench rest, or even Sweets 7.62 (use w/ caution as well).

Corey,

I don't think you have any worries. I was just giving you a heads up that you need to be careful, you can take off the edges of your rifleing if you over do it.
Britz is also correct about using other solvents, follow the directions carefully to prevent bore damage.

Great thanks guys. By the way I have used sweets 7.62, what do I need to watch out for?

Don't leave it in the bore too long and a light coat of oil when you are finished cleaning.

I don't think you'll find a better copper remover than many of the foaming bore cleaners. I have another post on here regarding my experience with Break-Free's version, but many of them have the same ingredient, and will work just as well. Anyway, it is easy, works great, and doesn't require a lot of hard scrubbing. Look for something that is ammonia free. After that, only use JB's for stuff that you can see (like dark spots, or rust streaks) and only use it a little at a time. I have some on my bench, but it rarely gets opened.
 
Corry - I just read your post - great question! I then read the opinions of others and had to respond. I used JB in my Anschutz .22 International Match Rifle for over 5 years. I routinely shot between 16,000 and 20,000 rounds per year between matches and practice. I'll save you the math. I shot between 80,000 and 100,000 rounds. That rifle was built for one thing: ACCURACY. In those 5 years, the rifle actually improved, rather than deteriorated. If my match rifle could take JB, I believe any firearm can take it. Do you envision shooting that much? Most people don't.

JB is a very, very mild abrasive. First, run a dry patch through the barrel to get rid of any loose fouling that may remain. Then, apply a little bit of JB on ONE patch, and start cleaning with gentle back and forth action with the cleaning rod for several passes. From there, keep running patches through until you get clean. This will take a long, long time! You might as well put on a good movie or a game and watch while you clean.

You will not destroy the barrel. I now use JB on my hunting rifle and my pistols. I don't use it that often - probably once every 5-7 cleanings, depending on the conditions under which I practice/hunt. I've not tried the foaming cleaners. I probably will when I run out of JB. Good luck and good shooting!
 
I have used it for years. It is abrasive but so mild it will take forever to damage a bore.

The patches never come out clean. Like JD said use a little for the stubborn barrels .

I also lap all my new barrels with it. About 50-100 strokes does it. I really do not know if it actually works that well or if it makes such a huge difference, but cleaning is easier after that. This was taught to me by a benchrest shooter a loooong time ago.
 
I will never be without JB bore cleaner or Isso, they are very good products that will remove copper fouling.
Back when i was shooting Bench Rest competition we would JB our barrels after every 50 rounds or after each Agg.
I have never seen a barrel that was damaged by JB bore cleaner.
 
Hey guys!............Along with the JB compound, which I have used for over 35 years, try some of thet "JB Bore Bright" too!. Just bought some for the first time a couple of months ago from Brownells. You use it after the compound is used........AND YOU THOUGHT THE COMPOUND ALONE SHINNED YOUR BORE WELL?........WOW!!! TRY the "JB Bore Bright!"
 
OK, now you have me thinking :shock:

I tried some of the foam bore cleaner and it took most of the copper out.
I don't remember which Brand name I bought. There still seemed to be some small amounts of copper left. Some guy at the range told me about Tipton Bore solvent. I bought some and that took the copper out! Now, that has an amonia smell to it. In this post it was mentioned not to use amonia based cleaners. Why not? Has anyone else used the Tipton stuff?
 
There's really nothing wrong with ammonia cleaners, except they will leave the bore more prone to corrosion, which I loathe (living in the damp southeast doesn't help, either). Anyway, if you use an ammonia based cleaner, just be sure you get it all out, and lube everything really well afterward. I lube really well, even without an ammonia cleaner, because if I don't, I get rust streaks pretty quickly around here. Even with our record drought! Go figure.
 
If you still had copper after useing the foam cleaner you should have gave it one more shot. I fill the bore and let it set over night. The next day a quick patch on a jag takes the copper out and 99% of the carbon. If there is a trace of copper another shot and overnight soak does it. A couple patches with Butches or Hoppes BR after does the job on any remaining carbon.
Ammonia based solvents do a quicker job on copper but also can etch the bore of your rifle. Most of these cleaners don`t recommend letting them sit for more then 10-15 minutes at the most in the barrel because of this. I used to use Shooters Choice at the range but no longer, especially at home due to fumes and the foams doing as good a job without risk to the bore. They do clean well but are hard on the nose, and the fumes are not good to inhale.
The mild abrasives like JB and Rem-Clean, maybe Iosso I haven`t tried it, are faster/better choices IMO. The ammonia types are dated cleaners and the newer non-toxic stuff is a better choice especially at home. :)
