Time for a New Barrel? -- Borescope Video

This is a Teslong borescope video of my barrel. I would like opinions from the experts.... the barrel has just been cleaned with Free All, BBS with a bronze brush, overnight soaked and brushed with wipe out and another overnight soak with C4. It has also been aggressively scrubbed with JB borepaste.
It's a 6mm dasher Krieger barrel on a Borden action with just over 1000 rounds on it, and we (the rifle and I) did not perform well in the last couple of LRBR matches.

To me that barrel looks Clean:) Now that you have done all that work on it and without wishing to be disrespectful or trite, why don't you shoot it with maybe an adjustment for seating depth:)
 
By chance, have you tried VFG felt cleaning patches for scrubbing with the JB Bore Paste?

For many stubborn carbon deposits, the pressure and area contact from the felt does a better job than a bronze brush or tight cloth patch. The use of Kroil with the JB Bore Paste works like a kerosene penetrant or detergent to help move the loosened carbon and seems to play well with the JB paste. The only downside, is you would need one of the cleaning rod adapters to be able to try the VFG patches.

I'd be careful not to make it too smooth. The worst copper fouling I've ever seen was from a pretty new barrel that had been polished to a near mirror finish.

I have been using the VFG felt cleaning patches for the past year or two. It is usually my last step in cleaning my barrels, except for a final patch of Lock-Ease. I run a couple of patches of Kroil through the barrel, and then use the "intensive" VFG pellet with JB borepaste. This typically does a good job in removing carbon, but things got out of hand this past weekend and I did not clean well enough between matches.

Don't understand what all the parallel straight lines are from. Look like the area in front of the neck? Could it be somehow related to using a bore guide and shoving a cleaning rod in? Don't have any clue as to why they are not in the chamber neck area and start in front of the neck. The lines are not rifling. Comments welcome.

If you have to ask! I have a Gradient Lens with a high intensity light but I'm not qualified to predict results. I suggest reading Tony Boyer - great book, I don't understand why the book has not had more attention - on the subject of what it takes to win as opposed to having a good time. Do you want to win or to learn and have fun?

I have had the Hawkeye borescope with the right angle adapter for the past ~10 years. I just can't record a good quality video using it, and recording a video from a Teslong is much easier.
I have the Tony Boyer book, and agree that it is excellent. I have read it many times and continue to re-read it periodically.
 
Very nice cleaning job. How many shots do you have to shoot now to get to equilibrium?

That barrel shows very little wear. No more than normal for sure. If I were you, I would stop worrying about cleaning and retune the load.

If you can’t tune it to shoot, get a new barrel. You have seen enough. Put your Teslong up. No one can look at a barrel and tell you if it will shoot. Some look bad and shoot good; others look perfect and don’t shoot.

Some years ago, I got a barrel from a maker that had 9 lands, and had been lapped super smooth. The barrel turned solid copper inside within 45 shots.

I gave it to a guy that did nothing but shoot targets once a week, and I made him watch me clean the barrel. The barrel was one heck of a good shooting barrel.
