Got a new 77 in 30-06 this fall. After 60 or so rounds I noticed the inside of the barrel at the muzzle was green with copper fouling. Never had a gun copper foul that quickly. Cleaned it with J-B compound and took all the copper out, however, during the inspection with the bore light I can clearly see the inside of the barrel looks like outside of a ring shank nail. Never seen that before. It has the normal rifling but rings for the entire length of the barrel. Anybody else ever notice or have any experience with this before? Haven't called Ruger yet.[/ATTACH]

It shoots ok, not a match rifle by any means. However after a few shots it quickly fouls and begins to wander. After a few shots the barrel can be cold/hot clean or dirty, the groups still open up. All the shots are off a bench with sand bags, with match 168 grain it will do an inch, not very consistently like I mentioned but its possible, then when the groups "open up" we're probably talking groups ranging from 2-3 inches. At 100 yards of course.
 
I ask because I can’t quite tell from the picture but it look like chatter marks to me which would accelerate copper fouling. It will likely settle down to some degree after quite a few rounds.

You should probably contact Ruger if that barrel is that unstable though to see what they say.
 
Looks strange to me... I would give ruger a call and tell them it doesnt shoot how it ought to.

How bad does it get if you just keep shooting it, say after 50 rounds or 100 maybe?

Maybe it needs time to settle in from a clean bore?
 
Yeah ive seen that on a savage, but not that bad, and inagree looks like button chatter.
Give ruger a call and explain the issue, betcha they fix it.

If not probably a good candidate for fire lapping.
