As a first time borescope user (and another Teslong buyer) I'd appreciate advice interpreting these images. The barrel is a 30 inch Krieger 0.308 with about 600 rounds fired, cleaned after each day's shooting, BTE and CU2 mainly, and using a bronze brush. Load is 155.5 gr Berger FB with 45.4 gr 8208.
To me there seems to be stubborn carbon, no copper plus firecracking. Might be OK, thats the question I guess. Rifle shoots fine. These pics were taken straight after more cleaning.
