I've got a Rem 700 heavy barrel in 308 that I purchased new probably 15 to 18 years ago. I haven't fired it a lot over this time period (probably 300 to 400 middle of the road handloads; mostly topped with 168 gr SMKs). The gun is very accurate but has a pretty rough bore and picks up copper fouling like crazy (particularly on the lands). I've been using Wipe Out to remove the copper and the first patch through the bore ( after the Wipe Out has been in for about an hour) pushes out what looks like blue soup. I think I performed some kind of barrel break-in when I purchased the gun but really can't remember the details. This heavy jacket fouling is after very few rounds (20 to 25).
The question I have is short of re-barreling: is their anything I can do to the bore to reduce this jacket fouling?
