After reading about it on here, I decided to try some on a rifle I had some copper trouble. It has not turned blue. Is it supposed to?

No not blue. Kind of a brown to orange color. Use a nylon brush and scrub it back and forth. Let it sit for 15 minute or so. Patch out and inspect the bore to see if it's needed again. tough copper may take 3 or 4 applications and turning the barrel to let it pool in different locations.

I have found that is turns an odd yellow-brown. In my experience it takes about 2 passes to fully clean an average barrel. This is about 10 times faster than Sweets or the Barnes solvent.

Pretty amazing stuff!

KG 12 and M-Pro 7 are really good barrel cleaners. They don´t smell like those ammonia based ones and do at least as good job if not better. I began to use these brands several years ago and don´t miss the others.

I am a convert to KG 12 and M-Pro 7. As described above a few passes with a nylon brush and let it set a bit. I start with M-Pro 7 for carbon and powder.

Occasionally I open the Hoppes' Bottle and run a few patches just so I can recall all those great memories of hunts gone by.

Another technique you may want to try is to saturate a patch with KG12, and SLOWLY run from breech to muzzle (taking care not to exit as you will be repeating the motion 5-6 times). KG12 etches the copper out, so 'rubbing' each part of the barrel with the wet patch(es) seems to work better than leaving the KG12 to saturate the barrel and then wipe it out.

Repeat the process a couple of times and then, with another wet patch short-stroke the entire length of the barrel. SLOWLY is the key word here, as one wishes to allow the fluid to 'work' on the copper.

After that, dry patches (or patches saturated with KG3) till you get no yellow stains.
My gunsmith explained this to me and I have been doing so ever since. The difference is marked...

best wishes,

I find that a lot of people in the maintenance or loading areas in matches --not to mention those folks on a bench next to me at a local club where we are just plinking or practicing--all fail to let bore solvents have sufficient time to work inside the barrel before brushing--and you need to brush--or patching or whatever--NO solvent will work to best advantage if not allowed to soak the fouling--another case of the hurrier you go the behinder you get--if you get no traces in a known fouled barrel the above might be worth reading again..........and, as a last resort, one might read the instructions..................

Yeah , I too have to crack open the Hoppes just for a little reverent ambiance.

I am going to give the KG12 a try. I have a 375 that has some copper that will not budge. It seems that KG12 is the solution (pun intended) of last resort but works well. I hope it does at least...

Brownell's and Midway USA are currently out of stock of KG12 but it's available at www.kgcoatings.com for $9.95 per 4 oz. bottle.

But KG estimates 10.20 shipping to me...uggg...guess i'll wait for Midway cause I need some other stuff too. Wish Trader Keith carried it, I have a few things I want over there too...

Try
www.eabco.com

Much better shipping 4.95$. Thanks for the link!!

KG12 is my favorite copper cleaner, it is amazing.
