Fouling in magnums

[linksmechanic]

Try using the wipeout accelerator with the standard wipeout. It will get any kind of fouling out in a hurry. Also I used to use jb paste alot on factory barrels until I figured out it seems to make them to smooth and actually caused fouling. I did a few tests on this. The Jb seems to work fine if used occasionally but I was using it on factory tube all the time. The severe fouling seemed to get better after I used Jb for awhile and then later on it came back. After scoping the bore it appeared the bore had become to smooth. Too smooth is not a good thing you want to maintain a certain finish just like on a cylinder wall. Bottom line is the Jb work well just use it sparingly.
