Sorry, no pics, but I've seen a few through my gunsmiths electronic bore scope. They look like they were sandblasted, fried with no lands for several inches. One in particular was a 6mm Remington of mine that was just used on a hot day on prairie dogs, around 60rds, and not shot particularly fast either! It was fried for about an inch, but still shot good, go figure. I dropped back to a .204 and 221 Fireball, shot slowly, solved that issue! ha I'm sure, on this forum there are some pics that will be coming your way!
