Copper in forcing cone

[garth64]

My 357 mag revolver has approx 2200 rounds through it; I clean it after every range visit; I just noticed the copper in the forcing cone, see pictures. The copper on top of the forcing cone has been there for a while, I thought it was pieces from my brass brush that got lodged in there when I was cleaning it; but, I'm assuming that it is also copper. How can I get this copper out of both places? I'll have to check back in tomorrow for, I hope, some responses; anyway, Happy New year!

Get some wipeout or outers foaming bore clean. Spray it in and let it set for the recommended amount of time and push a swap through the bore and done.

I've had the identical problem a time or two with a couple of my .357s. I've used Break Free Bore Foam, which I purchased from Brownells. You spray it into the barrel, let it sit for 15-20 minutes, then swab it out. In my case, it worked but less than perfectly. The copper deposit was loosened but it didn't come out with a swab. I used a dental pick to very gently probe the deposit and it simply dropped out of the barrel.

I should have added that, for the area between the forcing cone and the frame a little gentle probing with a dental pick will probably be all that's necessary to pop the copper out.

Best option: Buy a Lewis Lead Remover from Brownell's.
This not only cleans leading from bores it also cleans copper deposits off the forcing cone.

In the kit is a cone-shaped aluminum head. You put a brass screen over the head and pull it into the barrel and turn the handle.
The leading or copper is removed from the forcing cone instantly.

Kroil works like a charm and one bottle/tin will last years...

I recently had a major problem with copper fouling in an older Marlin336.

I used butch's bore shine which worked eventually.

The foaming bore cleaner worked good.

I think Sweets 7.62 worked the best.

As a follow-up; I used a product, G96 Copper solvent (only product available at local store) along with dental picks, and was able to get copper off. However, there are a few small spots of copper around the inside of the forcing cone; it seems they are embedded in the cone as the surface is smoothe. Thanks for all the suggestions.
