I have a 308 barrel which fouls badly. There is copper fouling which was in the barrel when purchased new, and it will not come out. I have tried multiple treatments of multiple solvents as well as Brownell's JB Bore Paste.
I have used the bore paste with patches as well as a bore mop.
With my cheap, serviceable bore scope, I can tell that it has helped, but there is still a ton of copper. The worst thing? It has fewer than 50 rounds down it!
I have thought about firelapping, but something else occurred to me: bore mops with pastes made from grease and the gris.
The firelapping kits usually have three or for grits ranging from around 300 to 800 or more. What if I used one boremop for each grit? I could start with a paste made with grease and 300 grit, coat a fresh boremop with it, and start running the mop back and forth from chamber to just short of the crown.
When going to a finer grit, the barrel would have to be cleaned of all the previous grit, and a fresh bore mop would be needed.
A hard question is how many strokes should be used for each grit? I am pretty sure that would mostly depend on how tight the mop is.
Brownells advocates using Kroil and JB Bore Paste on new bores as an initial treatment to quicken the break-in process.
Any thoughts?
