Borescope of my 338 Edge crown after 500+ rounds

I am not saying it won't work. I don't shoot pistols much. I can tell you it does very little in my magnum rifles to remove the carbon ring. I do use JB after every couple cleanings to help keep the throat smooth.
 
I have bore paste. Are you guys verifying the carbon ring is gone with borescope or by feel with cleaning rod?
 
Revolver is visual

Rifles, borescope.

My 7RUM would copper up terribly. When I got tired of pushing chemicals through paste always finished the job.
