My mk1 no4 .303 has a raised band about two thirds up the barrel towards the muzzle. I don't know whether someone cut it and re-lengthened it or if the barrel integrity was compromised so they cut out the effected area and replaced it. Anyone ever seen anything like this? It's about an inch and a half long, goes around the entire barrel, and is only raised a hair over what barrel is.

We need good, clear pictures. No one would cut a section out of a barrel and replace it, at least no sane person. It sounds like the barrel is bulged, probably from firing a live round with an obstuction in the barrel. Sometimes guns with bulged barrels will be reasonably safe, but I would recommend not firing the rifle until/unless the barrel is replaced.

Not a bulge, i'll try to get a picture but it looks like newer or different material then the original barrel. When I had it taken apart, cleaned, and tapped by a gunsmith he never mentioned it. They boresighted it too so I don't know if they would fire it themselves if it was a bulge.

If it's a bulge you would be able to see it looking down the bore.
