If you are looking for an affordable borescope you may want to check this out. Teslong Rifle Borescope, yes from China. https://www.amazon.com/dp/B07TTQF24F?ref=myi_title_dp It isn't up to the level of a Hawkeye I'm sure but it is handy, easy to use and affordable. It is basically a camera that plugs into a computer or phone something a Lyman will not do. It can capture pictures and I think even video. The pictures are very clear and can be quite large depending on the monitor you are using. Beware that you will see scary stuff inside a gun barrel. Not for use with iPhone or iPad.
