Those are some good images from a $50 borescope.
Never figured my uses would justify getting one, starting to rethink that.
Same here. It didn't bother me to spend the money for the bore scope, I figured I clean the guns thoroughly each time I use them and the patches come out clean when I'm done so it's an extra gadget I just don't want to be bothered with. And I don't go through a lot of ammo when I do shoot, I'm basically just an eastern deer hunter. Well some of the stuff I found definitely surprised me, even on a few guns that are new unfired(and I cleaned).
