bore solvent

Hi,
I've been trying many different bore solvent on a used rifle and have some discoloration at the muzzle. I'm assuming that maybe it will be that way and I have to accept it, or maybe it can be corrected.

Without a bore scope, it's really difficult to see the left over, burnt carbon from neglect of previous owners. What will work, as per my decription, and I hope someone else has experienced this too, to remove neglect?

try some bore tech elimator
this stuff works an does not stink

It's generally not necessary to remove ALL fouling from the bore, and is in many cases almost impossible. Also, if the color is green or blue, the color may be coming from a brass or bronze jag instead of the barrel.

Otherwise, for heavy carbon removal I use JB Bore Ceaner (the original, not the finer Bore Brite).
For heavy copper fouling, I use Sweets and a plastic jag; though if you use the JB the use of Sweets should be unnecessary.
