JB Bore Paste

[SCraig]

Ah, gotcha. Be careful with the muzzle crown.

I asked because the directions for J-B Bore Bright (which is basically a bore "Polisher") states, "Do not polish the chamber walls; a too-slick chamber will increase case thrust against the bolt and can damage the gun"

That agrees with what I've read several times in different places to avoid getting oil on the chamber walls. Oil there will reduce friction between the case and the chamber wall allowing the case (and the pressure that is pushing it backwards during recoil) to put more pressure against the bolt face.

I've never bothered avoiding getting oil on the chamber walls when I clean my gun under the assumption that a light coat of oil there will burn off quickly but when reloading ammo I do make sure to avoid any kind of lubricant on the cases since it might build up or last for more than just one or two rounds.

Anyway, thanks for the info and the clarification. I see what you mean now.

Well, I have to say it does a pretty good job. I cleaned my 1911 thoroughly after shooting it a month or so ago but there was one stubborn line of some kind of fouling I couldn't get rid of. I scrubbed it several different ways; once with Hoppe's #9 on a bronze brush, once with it on a patch and let it sit for a while, once with PatchOut and let that sit for a while, and it was still there. After all that I decided to just leave it and see if shooting bullets at it would scrub it out but then I got the JB Bore Paste and decided I would give that a try. One scrubbing 10 passes from chamber to muzzle where I unscrewed the cleaning rod tip and pulled the rod back through empty because I felt like it would have pulled those felt plugs off of the cleaning rod tip provided and I would have to deal with getting it out. The instructions said "10 to 20 passes each way" so I really only got about 1/4 to 1/2 of the recommended scrubbing, but regardless that band of stubborn whatever it was is GONE. JB took it out IMEDIATELY and the bore looks like a mirror without even using the JB Bore Bright.

So I'm on the same team as you guys are. That's some damn good stuff and I'm glad I got it. I'm also glad I asked for opinions here before using it since all of you put my mind at ease and were exactly, 100% right. So, once again, thank you all for your help in pointing me in the right direction. You are my Heroes Of The Week for this week

Do that a few more times and that thing will clean so easy you'll do it to all your guns, I even use it to polish the trigger track and some other small parts it does a great job when mixed with kroil into a paste glad it worked out well for you !!

I'm going to try that at some point. Someone else mentioned using it on slide rails and said it worked great so it had me intrigued. I've got one gun that needs some polishing on the trigger and sear and I think that would be a good test.

Thanks for the info, much appreciated.

Trigger and sear I use a white hard arkansa stone unless someone messed up the angles but I always finish with the white.

You mean the trigger bow ? If so yes works great after stoning the top and bottom of the bow then I use 2000 polishing sticks with jb and kroil and do a high polish on the top bottom and sides especially it's one step for getting a butter smooth trigger !
