removing copper fouling ?

I've been happy with MPro-7 and Hoppes Elite, but the easiest ones are the foaming bore cleaners. Breakfree makes one that is pretty effective on copper fouling. They may not be as aggressive as some solvents, but they coat the bore better due to their foaming action which means that the solvent stays where it needs to be longer than with the liquid solvents.

The fact that they work without strong odors is a nice bonus.
 
Break Free-bore cleaning foam

I've become a big fan of the foams, the one above currenty, cause its available locally.

I clean the bore as per usual with std Hoppe's and brush and patches. Then I do a foam treatment, letting the rifle set 10-15 minutes. You will not believe what comes out of the rifle! I swab again, then do an overnight foam treatment, swabbing with Hoppes as a last step.

I could not get Hoppe's Copper to cut my ADL's fouling problem, and using it after a match on F-T/R rifle was a lot of work too. The foam has eliminated a lot of scrubbing!

Ran some foam through an old Garand........good grief!
 
The regular Hoppes no.9 works pretty good for me, even better than the Hoppes copper remover. For severe copper fouling I've used the the Hoppes and gunslick foam which works pretty good also.
 
Holland's Witches Brew is the most effective copper fouling remover I have ever seen. Follow the directions and a little elbow grease and you will see the difference.

I use it in my .17 Remington and it makes an impressive difference.

I'm another sweets 762 guy. I havent used to many others, but I used it and it worked. Will probably last me a long time. I dont use it but a few times a year.
 
I've had good luck with the KG stuff. It's not magic, but does work. KG12 bore cleaner along with KG2 bore polish does a super job.

How are you determining that there's copper left after the KG-12? (Remember, it doesn't turn blue -- just brown crud comes out after a 5-minute soak/then dry patch.)

I will get some ME, however, and run the bullet weight-loss test between it and KG12. (Inquiring minds want to know !)
 
I can see the copper with a bore scope. I think the KG12 will be wonderful for rifles I am not in a hurry to clean. Put it in, let it set overnight, put it in let it set all day, etc. etc. When I need it clean in 20 min. Montana extreme seems to fill the bill much better. The KG-12 gets all the copper, just not very quickly.
 
Mehavey, did you get the ME and test it?


reynolds, remember that ME is ammonia, whereas the other products contain none.
 
I don't have any gunslick foam anymore. I used it up and now I'm sticking to the Outers and Breakfree foams. But every foaming bore cleaner that I can recall seeing has intructions about how long to leave it in the bore printed on the bottle.
 
another vote for Sweet's 7.62

It just flat-out works for removing copper. Quickly. But don't leave it in the bore for more than about 15 minutes or it will start to eat away at the rifling.
