clean copper fouling
working on cleaning out the copper in my 338. how can you tell if you have it clean? one person told me to keep soaking a patch and wiping out until no more blue shows up on the patch. i did this process severals times last night using bore scrubber and continued to get the blue on the patch after several cycles. when i went to the brush in between the patch would come out basically black. am i too impatient? do i need to continue the above or do you have any other suggestions.

I use patches and brass brushes soaked with Shooter's Choice mixed with a little Kroil until all of the powder residue is gone (the black patches), and then deal with the copper by using Sweets 7.62. After the Sweets I use the SC again to clean out all of the Sweets. I oil the barrel if it is going into storage.
I don't use the Sweets every time I clean, as the SC does a pretty good job. Sweets 7.62, Butch's Bore Shine, etc. are just stinky old ammonia based cleaners that disolve the copper. The copper cleaners do a good job but don't let them stay in the barrel too long (read directions!).
If you have black patches after brushing you are not quite done.

I run a wet patch with #9 benchrest and let it soak for a while,followed by dry patches. I then resoak the bore with #9 and use the J&B paste if needed. Cleans and polishes that bore. Then I swab with #9 benchrest, dry patches and then oil the bore.
