Copper fouling cleaner.

Not sure why a search did not turn something up, but what do you all have the best luck with cleaning copper fouling with?

I have some barns CR-10, but is there Ny thing else that might be better?

I have had great results using Hoppes No. 9 Bench Rest Copper Remover.

JB bore cleaner is good. Sweets 7.62 is the most aggressive that I have tried. Follow the directions on the Sweet's. It can eat the bore if left in too long.

Sweets 7.62 for heavy copper.

Where are you finding sweets?

 

[nettlle]

Brownells sells it.

KG12 @ MidwayUSA, it's a non-ammonia copper killer that works better than Sweet's and won't gas anyone in the same room. Being ammonia-free also means it doesn't etch steel if you leave it in the bore for too long.

Slop it in
Wait 5 minutes
Dry patch it (and all the brown copper crud it dissolves) out.

No scrubbing.

Well I can't see any more at the muzzle end, but I don't know for sure that it's gone all the way through the bore? I am working on a DPMS 308, would a bore light help any more than the light reflected of a white patch?

I used Sweet's 7.62 when I had some bad copper fouling on a hand me down rifle. It is aggressive but nothing to worry about if you follow the directions. The fumes are not even that bad unless you stick your nose up close, worst case scenario is open a window or turn on a fan.

I prefer to use Boretech Eliminator
- no smell, so indoor safe
- removes copper and carbon
But have to use nylon bristle brush chrome jag since BE will react to brass jag/brush

Ive used barnes cr10 with good results. It is pretty harsh so i dont leave it in the bore too long. I usually just put it on a patch and wet the bore with it and let it sit for 5 min and clean it right back out with some ballistol or rem oil. Usually once or twice is enough to clean the barrel without overcleaning it.

That's been exactly my experience with CR-10.

Your point of cleaning but not overcleaning is right on the money.
I've found that my factory hunting rifles like to have a bit of copper in the bore, so I go easy on the CR-10.

The OP's mileage may vary.

Me too. I actually think its better than Sweets, but without the ammonia.
