a borescope and a concentricty guage,,,2 things I wish i had never bought!!!! cause they drive me crazy.
anyway, i've had this lyman borescope for a year or so. i've looked thru a couple brand new barrels and some of my super used barrels... i like to look after cleaning just to make sure all looks good. i've come to the conclusion that I am not entirely sure what too look for, you would think a carbon ring would be easy to see and self explanatory but perhaps not... is it normal to find pieces of copper? do they brush out. what does bad copper fouling look like. what does bad carbon build up look like!
any experts on here got any tips. this is related to another thread i started about some unusual pressure problems i am having on a hunting rifle
