Home Forums Hunting & Shooting Ask The Gunwriters Best to remove cooper in rifle barrel

I wouldn't know what it best either but I know one thing that works, and that is Montana Xtreme Bore Solvent or their Copper Killer if you really want to get copper out.

The breech end of the bore is plugged a 50 cent tapered rubber stopper available at most any hardware store, then I squirt two or three droppers full of bore solvent down the muzzle - the Montana products come with a small pipette dropper thingy. Then I take about a 4" square of doubled over plastic grocery bag and secure it tightly over the muzzle with a rubber band wrapped several times.

The rifle is turned up and down a few times to spread the solvent over the interior, then I lay it flat and walk away. If I remember, every couple hours I might turn the rifle over, or not.

After a few hours or if I started in the evening then the next morning I remove the plastic grocery bag and let the now blue solvent run into a trash can and remove the breech plug. Patch #1 from the breech end pushes out the remainder of the blue goop. Patch #2 for insurance helps dry it. Patch #3 has lighter fluid or maybe 90% alcohol on it to clean and dry off any solvent left. Patch #4 is dry. Patch #5 has Montana Gun Oil on it to oil the bore. I suppose I could eliminate patch #2 and/or #3 but I like to keep some anality in my routine for old time's sake.

About 5 minutes or less total time spent cleaning a very, very dirty rifle bore, no brushing or scrubbing required. I know it is clean since a test patch of Montana Copper Killer on a non-brass anywhere rod and patch combo comes out with zero trace of blue, and that stuff will turn blue if you bring a real copper penny within three feet of it.


Lots of ways to clean a rifle thoroughly, I certainly don't claim that my way works and no else's does, just that this is the way I do it and it works. I hear Wipe-Out works just as well but I've never tried it so can't say from personal experience.

One "problem" I had using wipe out....had some rags on top of buttstock to avoid getting any solvent on stock as I was running several treatments thru barrel from bore end, letting soak for hours and repeating. Well, when it was finished and I removed rags I found some Wipe Out had got between rags and ran down side of stock which removed some of the finish. So avoid getting any on your stock, or wipe off immediately, don't be a dumb-azz like me.

Yep.

Did the same thing and of course, it was a really nice Tung Oil/Urethan finished rifle I had done.

If you guys would buy schittty rifles like I do you wouldn't have that problem......

I like Wipe out and Patch out, have used Eliminator and others.

Are JB and I the only DBC fans?

Properly applied DBC treatment, the copper problem is almost a non problem.

I didn't know Cooper could climb in a barrel??

Crow hunter,

I've tried KG-12 in several barrels. I may have a bad batch, but it simply has not removed copper as well as several other products. The first barrel I tried it in was on a used .270 purchased here on the Campfire Classfiieds, which was heavily copper-fouled. I gave up on the KG after a couple of days of not making much headway. What method are you using? I followed the directions on the container.
