JB and Kroil...

Strong ammonia cleaners certainly can and will do damage to a barrel ( Krieger specifically warns about this) I agree, as long as they are not left in for extended amounts of time and are followed up with the proper neutralizing cleaners, they will also work fine. I never suggested leaving the high ammonia content cleaners in for extended times, just simply mentioned the Wipeout can be left in for several hours without hurting a thing. Its pretty simple, use what works for you.

That's really bizarre. JB/Kroil is the only thing that I have found that DOES remove copper effectively! Effectively being the key word, because a lot of ammonia based solvents remove copper....slowly from my experience.

I am a little lost, I guess. The JB' is the scrubber and the Kroil is the lube?

Don't get me wrong here as that is the same thing I used for a while.
They both have their uses. But to get all the copper out, is a lot of scrubbing. Then it is questionable if it is clean as new, or close. I thought back then the Kroil and JB was doing the trick. Then I ran some Barnes through the bore and got blue patches.

I am no scientist, but I suspect the Kroil and JB just knocks everything down smooth?

Some interesting angles and thoughts here on this thread.

One thing I have fought with is carbon. I can't say I have a carbon ring at the throat on anything, but then I wasn't looking for such a thing either.
Worst carbon cases I have ever fought with was on some of the milsurps I play with. It absolutely crazy how many layers of gilding metal,carbon and powder can build up in years and years of shooting.

A long soak in Kroil is a my beginning attack method. Plug the muzzle, filler' up, stick muzzle in a can and walk away and forget it.

Kroil and Hoppes, smell of a good day! ;-)

Here is my cleaning regimen...

Montana extreme bore solvent...2 patches. Let soak for 15 minutes. Wipe with 1 patch again of bore solvent. 2 patches of Kroil. Wrap patch around 1 size smaller bore brush, rub JB into it. 30 strokes down and back the barrel. 1 patch of kroil on a jag. Go back to the brush with a patch of JB and 30 more strokes down and back. 2 patches of bore solvent to clean out the bore and I like to finish with Break free CLP personally. I use two patches of CLP. That's the cleanest I have ever seen. You could probably only use one 30 pass regiment on rifles normally cleaned this way?

It is deffinetly not leaving copper, because the bore solvent on the patches at the end would be blue if there was still copper. It sounds like a a lot, but it's honestly 30min and done.

The best way to scrutinize how well your cleaning method is working, is invest in a good borescope and examine the bore. If that is not an option, use a rod and attachments that are non-reactive to your solvent and leave no false color.

I have never used the J B, But I have been using the kroil on all my guns from the time they were new. love it

i got a new custom barrel from BullBerry Barrel Works , they use EEZOX exclusively .., I've been very happy with it. Anyone else use this product ? Haven't seen it mentioned .

Tell me about what chem reaction happens with the Hydrogen Peroxide and alcohol

The best I have found is KG-1 for carbon. Then I use Sweet's for what little copper my barrels pick up. I have in the past used GM Top Engine cleaner and Kroil but, quit that when I found KG-1. Besides you can't get the top engine cleaner anymore.

I have been using JB every couple hundred rounds and then Kroil for regular cleaning...all with good results. When I first used JB, I was surprised how much it improved accuracy. A couple of months ago, a friend at the range suggested I try Wipeout and I was amazed at the amount of copper (blue) I got out. Now when Inuse Wipeout a get very little, if any copper residue on the patch. I now use Wipeout regularly and JB and Kroil every couple of hundred rounds...this combo Siemens to work very well. I usually clean my bore right after I shoot whether it's just 5 rounds or, in the case of handguns more like 25-50 rounds. I'm wondering if I am doing more harm than good when I clean my rifle barrels after only a few rounds. Maybe I should clean it after say 15-20 rounds ...your thoughts?

I usually clean after 75 or when I notice that groups are starting to "open" up a bit. But, never as often as you do. To confuse matters more read this, http://www.6mmbr.com/borebrushing.html Long read but a good one.

Thanks for your input...I'm going to experiment a bit with # of shots between cleanings and will continue to use Wipeout regularly and JB after 150-200 rounds. I don't usually use a brush and I regularly shoot 100 yard groups that are at or under 1/2 inch with both my .308 (Mauser 3000) and my Rem. 700 in 300 WM.

I have personally used every combination of products mentioned in this thread. They all work, however the kroil / JB compound is a favorite. I use it on plain felt pellets sold by Brownells soaked in kroil covered with JB paste, but only when I want the barrel squeaky clean , or if it is a new common 22 rimfire to semi lap the barrel. I have never had it hurt the accuracy of a barrel, it just gets everything out. Now that might not be the best thing as a slight coat of copper doesn't hurt anything, but sometimes it is just good to know everything is clean.

Desertcj, not knocking your method, by all means if it works, your happy with results keep after it.

Just asking, bore guide I hope. Those total of sixty strokes, or down and back of 120 is a bunch. How many rounds are you shooting after a cleaning like that?

My aim, pardon the pun, is to run the least amount of patches or brushes through the bore for the best cleaning.

I used to never give it much thought. Clean it till its clean. Since entering 17's and 20's and asking,reading,exchanging emails, I am way more cautious of my cleaning.
I have bore guides for everything that they will work in. Any of us still stand a chance of banging somthing around and doing some damage in seen other than groups.
One friend uses a patch workm and swears by it. I tried one years back and the **** cord broke, that was a mess.

Yes I use a bore guide and a Dewey cleaning rod. I'm assuming that you are asking how many rounds am I shooting before a cleaning like that? I usually shoot about 50 through a rifle at a time when I am testing loads. I did mention that only 30 strokes with JB would probably be fine unless the bore is really really fouled. Even 60 strokes doesn't seem like a lot to me compared to what I went through before with gunslick and a nylon brush!
