Tell me what this means.

I'm following this on gunbroker, and I'd like your opinion on this bore. What is the ring mean?




I see the bore is rough, maybe too rough, maybe would shoot just fine. Never know till one shoots it. The rest of the gun looks great to me.

Can't see the outside of the barrel surface, but from the inside, it looks like a bulge.  If it is a bulge, you should be able to see a slight bump on the outside of the barrel.  Particularly easy to see on round barrels, such as this.  If this is the case, it was probably caused by an obstruction closed to the muzzle end of the barrel.

There would be two possibilities that I state.  It is a ring from a stuck bullet... but the outside of the barrel does not give a bulging appearance.  The second is it is just crud from sitting or hanging.

Like you state it is and iffy call without seeing first hand.  I have read where a bulge that far up the barrel may not harm the shoot-ability of a rifle.  I did buy a rifle one time with a ring just up from the chamber.  IT DIDN'T look like that pattern.

You are right that that barrel after a good cleaning and scrubbing would probably shoot just fine.

It is an original by goodness.  If I could(I cannot), I would bid as high as I could and just hope to win that good looking Original, in the last caliber you need or I would want.

Good luck to you and your decision to bid.  I hope you win.

Buck go to his link there are about 126 photos.  Maybe you can see something I do not.
