Using a Lyman Borescope, let's take a walk through the 20" Team BBL at 200 rounds. Be aware that borescopes can be tricky - one can easily misinterpret things; detritus from a dirty barrel can look like pits or other problems that aren't actually there. So this was done after a rather thorough cleaning.
Starting with the crown, and doing a rotation for each shot (i.e. 365 degrees of photos), to seek for any issues. Start with a rotation around the crown:

Crown looks sharp and good to me.
