Bore Scope Shots IF Barrel

[Billm]

These are a couple of images of an airgun barrel. The first four images are of a new barrel that hasn’t been shot or touched yet. You can see one of the lands. I’m curious others see when they look at these images, just general observations about the lands etc.? The first two images show a side shot of the rifling and bore. The third and fourth image's show looking down the bore. The fifth and sixth images show similar angles looking down a different barrel - my Sub-MOA barrel which has not been cleaned after shooting pellets.
