J.B. Bore Paste.
How many of you guys use it occasionally, or have used it ever?
Just polished the barrel in my Condor with some of this stuff. I made about 20 (very careful) passes both directions with a .22 Dewey rod with a Beeman Bronze brush attached, (man, what a mess). After that, I probably put about 30-40 patches through the barrel to get all that gunk out, it took quite a while. Also had to use Q-tips to carefully remove the excess paste that built up on the outside breech end of the barrel, I don’t think that can be too good for the O-rings. Despite how tedious it was I must say I am amazed at how clean & shiny the barrel is after all this, to look through the barrel it is almost blinding!
I know it will get dirty the first time a pellet goes through it again, but I guess this stuff is supposed to polish the metal in the bore? And leading should not really be a problem so long as you lube your pellets, and don’t shoot alot of pellets with antimony in them like the Crosman Premiers at high velocity, and so this shouldn’t have to be done very often if at all again, unless the accuracy or velocity drops off dramatically.
Too bad they can’t make this stuff a little more attractive looking, it looks like Milorganite paste 😯 but it doesn’t smell bad, kinda like shoe polish or something.
Anyways, if you have something to add I would be glad to hear it, thanks.

Seems overkill for airguns, lead fouling is easy to remove without resorting to abrasives.
Your missing the point. we aren’t using it to clean a fouled bbl., but rather to polish the lands and groves in a new bbl. to remove manufacturing flaws,and to gain a smoother interior, resulting in both improved accuracy, and remove much or the rough surfaced to stop fouling in the future before it can get started. Bench rest competitors have been using this technique for years. A win- win 🙂
Once this is done, clean with goo-bgone or somthing similar, followed by dry patches until clean. Finally, use a soaked patch with FP-10 on it and let stand for a few hours. Over night is possible.
Re clean with a dry patch, and go shoothing!!! It will 😀 give thousands of rounds now with futher cleaning. All more accurate!

Yep, all new guns/barrels get polished with JB Bore Paste using a tight patch and a Dewey Cleaning Rod with the patch being pushed from breech to muzzle whenever possible…
If not possible then a tight patched pulled with a piece of coated fishing line from breech to muzzle…
After polishing, I run patches with Goo Gone followed by dry patches, the pull a patch with FP-10 a few times followed by a dry patch or two…
On problematic barrels/guns, I will also re crown the barrel using JB Bore Paste and a dremel bit on a variable speed cordless driver/drill as well as polish the transfer port if applicable and open up the lead in with bore paste and a dremel bit…

I have used it only for heavy-fouling centerfire rifle barrels.

Good stuff, thanks for the replies. You’re all so much help. 😉 I’m still fairly new to some of these airgun things, but I try to do my homework first before attempting anything, honostly I do! 😀 There isn’t a better place to learn about these matters than the TAG!!! Any time I ask something, I am astounded by the overwhelming knowledge that is abound here.
BTW, I have used SimiChrome to polish chrome, polished aluminum & such on motorcycles and cars before. SimiChrome is really good stuff, but I never thought of using it in a rifle barrel before. Next time the barrel needs cleaning I will give ‘er a try.
Thanks, take care……………
Works Great! but I only use Flitz, or simi chrome in mine. JB is a little too coarse for me.
Now, STOP using the bronze brush with the paste. Not only is bronze bad of some bbls, the paste needs a solid backing to work. Other wise, it only goes up into the bristles with out doing much more than lubricate the brush. A good quality-tight patch on a nylon button works very well. It will polish the lands and groves very well!
Not only will this give you a more accurate bbl., but it will take much-much longer to get dirty again plus making cleaning in the future much easier! 😀
Make sure you do it from the breach end, and DO NOT let the rod touch the crown area of the bore.
I push the patch thru the bbl. until I feel it leave the muzzle only slightly using the tip of my finger of my off hand.

I have it, but have never used it in a barrel.
JB is the best bore cleaner around. Ive never had a barrel disagree with it.
If you want a mirror shine, after its clean, use something like Flitz or Simichrome (midwayusa.com). You dont want to overdo it though.
i use it in all of my guns and it does help with acuracy dont use it often just when i notice the groups open up it works
Would be a good idea for anyone else that wants to
do this to, pull the barrel out….You can also polish
the outside of the barrel while you’re at it….Other
than that I have heard that it takes the sharp edges
off of the rifleing which prevents the pellet skirt from
getting damaged….Suppose to improve accuracy. Couldn’t
confirm or deny that one because I never shot an AF gun
without a polished bore….I used Glover Valve gringing
paste Fine and cleaned up with GOO Gone.

The ole JB Paste trick eh ❓ … 💡 Hum..I think Im going to get me some JB Paste. 🙂
I have always been a Solvent man. Lately for airguns I tried some cleaner degreaser for all airguns from Straight shooters. And I just used a patch. To be honest I never really cleaned my air rifle much before. It was pretty dirty. So…then I said To Myself… “CLEAN THAT PUPPY” 😉
Hey I didn’t post this on the Chrony topic again did I 😯 ❓
