More on Borescope

[Old Tanker]

Daughter gave me a Teslong wifi borescope for Christmas. Lots of Copper and some carbon that I can deal with. However, what am I looking at in this pic. Rem 700, XCR, .223, 26”. About 800 rounds through it.

Those are tooling marks. Most if not all factory barrels have similar chatter marks, they are just part of mass production. If the rifle is shooting well, and I assume it is since you have 800 rounds through it, there is no cause for concern there.

Thank you. Rifle shoots well for factory. I can consistently keep it at or below .5” if I’m doing my part. Shot a couple at .350. Certainly not a bench rest gun. My daughter’s gift of a borescope is received with mixed emotions. I used to think my cleaning regimen was good. I may reply with another pic, if you don’t mind. Neck of the chamber looks rough, almost like fire cracking. I’m not getting any carbon below the neck on cases.

Would be glad to take a look. My first post after getting a bore scope was along the same lines about cleaning or lack there of in the past and how much more time I was spending cleaning. I took quite the ribbing but all was good natured.
In my experience .223 doesn't really eat up barrels much unless they get run hot like in prairie dog hunting without a cooling system in place. Also, in the barrels I have with fire cracking it is mostly in the first few inches of the rifling more so than the neck, which is protected somewhat by the brass neck. Even then, most casual shooters continue to shoot a barrel until accuracy starts to fade.

I discovered that what looked like cracking was spillage of solvent from when I removed the bore guide. Helps to mop the chamber. Barrel looks good after cleanup. I used Rem 40x which, I suspect, is a little milder abrasive.
