What is this, ring in barrel:

Should have said it to begin with, no bulge on outside.
It is so uniform that it looks like the spot in the barrel where the bullet is first making contact with the lands and grooves. What is the gun and how far into the barrel is the ring? Have you tried brushing it? Have you tried one of the lead cleaning products? What type of bullets are you shooting?

It looks like fouling to me.

Its an old 1917 and it was there when I acquired it. I am sure it has had a little of everything shot through it in 90 years. It is beyond the ejector housing, so I don't think this is where the bullet is initially coming into contact with the lands which leads me to another question about bobbing it if it proves to be a danger. Oh, it doesn't brush out, I have not tried any of the lead removers, however.
It looks like lead fouling to me, but then, this is a strange place for it. It is possible that a bullet was stuck in the barrel and then was shot out by another round, but then you'd expect an outside ring also, and ringing ears.

I think it is possible that it is damage and the bulge on the outside may be almost undetectable. BIG QUESTION, if so , is this dangerous?
My bet is it is a squib load ring, but the initial bullet was loose enough that the second bullet pushed it out without causing much of a bulge. Take a cleaning rod with a very tight patch on it, and slowly push it through the barrel. See if you feel the resistance change at this spot.
I very much doubt if there is any danger in continuing shooting it. If the accuracy is O.K. I wouldn't worry about it.

Use a micrometer on the exterior of the barrel. It may have a bulge so small you cannot feel it.
Take a small wire, like a paper clip, and sharpen one end. Then bend it to a short 90 degree angle. Insert the bent end into the barrel and feel for the bulge. With a little practice you will be able to detect if the mark is on the surface or if it is really an indentation/bulge into the lands and grooves. If it is an indentation, it will probably be uniform around the interior. This was probably caused by some obstruction in the barrel when the gun was fired.
A large interior bulge will allow pressure to pass around the bullet from back to front. This looks so small you will probably never have a problem.
I would not consider it dangerous and would not hesitate to shoot the gun.

Based on reviewing the photograph in your first post, and the one in your last post, I believe you have a slight bulge approximately 1-1/4 inches behind the muzzle.
If you're happy with the gun's accuracy, I would just live with about it. I see no danger in shooting the gun.

Moly?
Not sure at all about this, but I have read about moly coated bullets causing permanent rings in barrels. The moly gets deposited in rings through the barrels, and then firing bullets after the rings are formed heats the moly rings and makes them almost impossible to remove.
Anyone have more experience with this than me that can confirm or dismiss this?

OK, another question. How hard would it be to replace the lanyard ring that some genius sawed off, and how hard would it be to find one?
Thanks for letting me ramble.

No, moly doesn't do that, and I don't think anybody uses moly in pistols.
That's a high power rifle "thing" and its starting to fade from use now.

The lanyard ring is retained by a cross pin through the frame under the grips.
Replacement requires only driving the pin out.

Another way you get rings in pistol barrels is by "shooting the lead out".
People shoot lead bullets then try to clean it out by firing jacketed bullets.
If there's just a little too much leading, the bullet can't push it out of the way fast enough, and the pressure blows a ring in the barrel.
Its common to see ringed barrels with almost, to no bulge showing on the outside.

Thank you,
Very informative and great place to get the lanyard ring.

Yep, that sure looks like a rung barrel, due to a squib load sticking and another fired behind it. The barrel does appear to be bulged and the bulge is visible to me in you initial picture. If you look down the side of the barrel toward your thimb, you can just make out the slight rise down the barrel, which appears to coincide with the inner ring. The gun will probably function just fine and accuracy may or may not suffer. I've seen competition guns get rung and still shoot very accurately.

The paper clip is a good idea, but I graduated to one of those dental picks because it gets farther down the barrel. Just one or two careful pushes will tell you if it's lead. If it is, don't use the pick further...get a lead remover.
it looks kinda rust to me, could be somewhere along the line somebody squib'd it, got home, put it up and then let it sit before tapping it back out, and it sat long enough for rust to set in where the bullet was stuck
Looks like it was caused by a squib load. As long as you use standard .45 ACP loads, it should be OK to shoot.
