The Very limited experience I have with someone else's bore scope in my shop leads me to believe:
1. they are difficult to use and it requires an experienced and knowing operator.
2.For older or used rifles you are almost certainly going to see things you don't want to and aren't equipped to truly understand.
3. There is a huge amount of surface area revealed and unless you're in process, (can compare inside to outside) knowing even what region you were in is nearly impossible to determine.

While a bore scope in the hands of an experienced person is a marvel of wonderment. Anything less almost for sure will be confusing and concerning.
I'm sure it is possible to take pictures with one, but I have no idea how...
BTW: most of my experince was looking at the bores of brand-new quality barrels, the used barrel I tried was like crawling down a small NY city sewer, and it didn't look too bad with the naked eye!
