Teslong Bore Pics

[timeout]

I just went down the borescope rabbit hole. My main interest at present is to learn about my cleaning regimen. Two pics posted below are from a barrel with approximately 250 rounds on it and it probably hasn't been fired in at least 5 years. Last time it was used my brother heated the barrel up more than I would have liked and I do see a bit of firecracking, but not terrible. My first question is why would the pics have such a blueish tint? I'm guessing it may be due to a light coat of Kroil before removing the barrel and storing it. The first picture is at the end of the chamber where the cartridge neck ends. I'm assuming this is a carbon ring problem. What say you guys? The second picture is mid barrel and it appears to have some carbon. Is that assumption correct? Thanks in advance and I'll try not to bother you guys too much with borescope pictures, although I have a lot of barrels to go

I'd give it a good cleaning then look at it again.

Thanks! That's the plan for sure.

You can adjust the filters on the app looks like it's on blue.
And yes needs to be patched dry.

Does look clear.

My take on the first picture is a nasty carbon streaking on the land. That will take a major carbon remover and lots of brush time.

To get rid on near the same thing in my AR last week I had to use some serious carbon cleaner, Iosso and a wire brush on a drill. That hard carbon build-up is beyond the tough but I got it out.

Wire Bush On A Drill !
That's serious !

I'd say
Patience and persistence with rod that follows soak a bit wet and losso on a patch, brassbrush a few times..
Repete ....
Doesn't need to be like new, cause it's not.
Actually looks good like it is.

Get some JB or Iosso. Use it on a wire brush with a pad. It will clean things up fast.

I have both. Will try Iosso on the end of cartridge neck area.

Both work about the same. Use a tight patch fit on a brush that just allows you to work it back and forth. Use a bore guide to keep trash out of your trigger.

Do not use a drill.

Not wanting to get away from the OP's original topic.

Once that carbon gets shot over and hard, it is near beyond normal cleaning to get it out. The chemical I use is not allowed to be mentioned on this forum. After using it and brushing with a spinning brush, then the various JB and Iosso polishes come into play on a different brush.

I was sold a very slightly used barrel for my AR as a target alternative. Looked clean with only a reported 100 rds through it. I did NOT borescope and did maybe 250 rds of testing through it. Noting a primer pocket tightness difference, I cleaned and used my borescope. OUCH!

Alex Wheeler told me/us firmly - a spinning brush in the throat and first couple inches of barrel (where most of the carbon accumulates) is way easier on the barrel than the intense heat and scouring of a bullet and powder. I remember what he says and listen. This is not my first rodeo with that method if I find neglected proper cleaning to have caused that carbon deposit. My uses of this method have all been successful, so far.

The Teslong is a good choice for an inexpensive look at something you cannot really see with the naked eye.

I always use a bore guide. Have heard of a drill being used for carbon ring in the neck area, but I turn the brush by hand.

Thank you Captain.

Does it look blue only when inserted into the barrel?

I got the blue tint toned down a bit in my pictures program.

I soaked the barrel and chamber neck area in Boretech carbon formula, then carefully used a bronze bore brush. It looks like I removed the one carbon ring from the neck area that evidently the brush isn't getting completely into the corner. Also had some tiny debris on the mirror in the first pic. I'm guessing if I get it this way every time I clean the barrel it won't be an issue? The great news is that while digging through barrels I found one I had forgotten was in my stable. Thinking I need to buy an action for it and build another prairie dog rifle.
