You can get a great bores scope from teslong for about 40 bucks on amazon. They come in iPhone and Android versions, just make sure you get the one with the 5mm diameter so you can do 20 cal, and 22 as well. You can also get a set of mirrors that have different sizes like .284 and .30 .375 etc ends for them to get clearer pictures in the larger bores. I use mine all the time.
