copper fouling removal?

How does JB's bore paste rate as a copper fouling remover? I have heard that some people avoid it because it is slightly abrasive. I have been using Bore tech elimantor and I can never seem to get a copper-free patch with the stuff although it may be that I am being fooled by the reaction of the solvent and the brass jag?

Re: copper fouling removal?

I have used JB's on a couple of old rifles that were not cleaned properly through the years as well as a couple of .22's that just had tons of rounds through them. I would not rcommend it though for general cleaning.

I read the pages (links below)from the 6mmBR site amd picked out what I thought were the top components for me. I liked the idea of the spray on carbon remover but in past experience, it always seemed I ran out of something in a can long before I did a liquid in a bottle. I chose to go with the TM Solution for the carbon and the Butches Bore Shine for the copper. I also keep a bottle of Sweets on hand for the heavy duty cleaning. A small bottle of Kroil is also helpful for an after cleaning oil of the barrel. The stuff will get into places standard oil will never see.

Here are the links :

Another thing I switched to and it has helped, with what your referring to in reguards to false reading on the patches, is a Tipton Ultra Cleaning Jag - Nickel Plated Brass. I have found that this will definately cut down the false reading almost completely. I use 1 3/4" patches, which cover the entire length of the jag so as not to allow contact with the bore. You might have to try different patches with them as they run just a tad bigger in doameter than regular jags. I found that using Pro Shot patches with the nickle plated jags and Tipton patches with the standard brass works just fine. The Tiptons run just a tad thicker, and you can still use them with the nickle plated jag if you just drop down a caliber size. I only use these for .257, .277, and .284 since these are the main calibers I shoot. They are also the highest velocity and seem to foul just a tad quicker.

hope this helps,

Re: copper fouling removal?

An acquaintance of mine uses JB every 30rounds in his big guns and every 40 in his varmit guns. He has shot out alot more barrels than me and claims they make his barrels last longer and shoot better. He uses them on his custom barrels and his factory. I use it every now and then. I to, find it helps it with accuracy if you're gun dosen't want to shoot good. some of my guns dont shoot worth crap unless you use JB every time you clean. a 300wsm i know of is really picky withou it.
I dont know who ever came up with the imaganary word of "Over Gunned"

Re: copper fouling removal?

The best copper remover that I have used is Barnes CR-10. Soaked patches, sit for 10 min and clean out and repeat. Its potent.

Re: copper fouling removal?

In my experience, CR-10 doesn't hold a candle to Montana Extreme 50BMG. For that matter, neither does anything else, although Wipeout comes in a close second.

As to the subject of false copper readings, I was having this problem with 50BMG since it's so strong and here's how I solved the problem. First, I apply it (after cleaning for powder with a good powder solvent) with a bore mop that has a steel core instead of using a patch on a brass jag. I believe I got these mops from Walmart. Then after waiting 10 or 15 minutes, I put a patch on the end of another clean mop and push it through the bore. If there's blue on the patch the only thing that could cause it is copper in the bore. I sometimes also use a nylon brush (with steel core) with 50BMG. Just depends on how much copper's in there based on the first patch that comes out.

Re: copper fouling removal?

When I have to clean at the range quickly, I use Barnes CR-10. Its effective but nasty stuff. I much prefer to use a foaming bore cleaner (seems like all brands are about equally effective)and let it sit on my kitchen counter over night. No brushing, no mess, no smell, less risk of bore damage due to poor cleaning technique and all the copper is GONE with one patch before breakfast.

Re: copper fouling removal?

I've been enjoying the use of Warthog 1134

Also using Wipeout but its a bit behind Warthog in my experience.
