I, too, have a hard time believing that firing a few target loads caused any kind of damage to your barrels.
Have you cleaned your gun since firing those shots? It only takes ONE shot to leave behind powder residue and plastic fouling. I could see normal fouling being mistaken for scratches because, especially after only a few shots, the fouling would be minor and may appear to be pits and scratches when actually it would clean out easily.
My advice is to clean the gun thoroughly with solvent and a brass brush. After wiping with several patches, with the last one lightly oiled, look again to see if those lines still appear. (NOTE: Make sure you go easy on the gun oil. Anything more than several drops on a patch is more than is required and can look streaky itself.)
If those lines/scratches are still there after cleaning, I'd have to agree with previous posters who think you're seeing the forcing cone. The only other possibility (very unlikely) is that there's a visible line where the barrels are joined to the monoblock (assuming monoblock construction). You'd be the first person I've ever known who could see the joint on the inside of the barrels, but I suppose it's still possible, if the barrels are defective.
Wow did this ever get off topic, however it is quite entertaining!
I dont think it is the forcing cone, as my forcing cone is before the actual ring. I'm guessing it tapers out about an inch ahead of the ring. But I could be wrong. And I dont think it is the monoblock seam, as it appears to be a series of scratches in a 1/4 thick ring.
Here is a chronological description of what happened to my Rem870 SuperMag.
Bought it brand new, barrel was impeccable.
Cleaned it right out of the box with Remington Bright Bore, an expensive bristle tool, patches and used G96 all over it. Perfect barrel.
Fired about 40 rounds on a rainy day.
Cleaned it up with the same products, perfect barrel.
Fired 60 shells, and cleaned again with the same product. Perfect barrel.
Fired 5 shots just fooling around at the action range, got home and this ring existed.
Gave it a very thorough cleaning, the ring faded a bit but wouldn't go away.
Fired about 140 shells, gave it another very thorough cleaning, and the ring seems to have become permanent.
Any ideas? Why would it suddenly appear?
Hmm... I do recall reading about a wad that was defective and could get stuck in the barrel. I don't recall the manufacturer or wad model. But if this was the case, the next round could cause damage. Maybe time to take it to a gunsmith?
Of all the non Brass reloads the Rem. Gun Clubs work well. The new WW AA's suck.
Plastic fouling eh? Is that anything to worry about, considering it wont go away?
Anything to support that comment? I'm trying to figure out what ammo actually is actually decent vs literally terrible.
Scouring pad wrapped around the brush is a great way to get rid of fouling. You should see little pieces of white plastic bits on the pad.

I'm pretty sure there's no wad in the barrel since he can look through it to see the "ring".
If scrubbing it causes the "ring" to fade a bit, then my guess is that its just some plastic fouling.
