I have recently broken in a Sako 75 and even after 15 -20 shots the copper and powder fouling can be removed with 3-4 patches of Butch's....great! I then use a bronze brush with boreshine and patch clean.However, carbon fouling is a different matter. After the patches of Boreshine come out clean I patch with oil(Parker Hale Express) - but as soon as I oil the barrel out comes carbon(brown)fouling.... 25 applications later the oily patches are just about clean. Surely there must be a better (more efficient)solvent to rid the barrel of carbon? At this rate I will be going through a can of oil and bag of patches per month. Maybe this is not excessive cleaning.... or could it be that the powder I use is prone to carbon deposits (Reloder 7)?
I would not claim any expertise on this subject, but I believe that ignited powder produces two types of fouling from the different ingredients...known as 'powder'(black)fouling and 'carbon'(brown)fouling. I read somewhere that the carbon fouling is produced by a graphite type ingredient.
Take a bronze brush and a cleaning patch covered in JB compound,and work it back and fourth completely through the barrel about 60 times non-stop.Then rince out with a light solvent on a patch.Then repeat the whole process again.Every 5 magnum rds,20 270-like rds,60 308 rds.
