Dirty barrel.

I appreciate all the comments and interest in this process.

So after considering the various possible outcomes; I decided to treat the barrel.

I used the Sodium carbonate with one 13 minute cycle. The barrel had not been fired since the last normal clean.

4mm bar stock is used for the Positive; insulated with small "O"rings. Plugged the muzzle with a cork and filled the barrel with the sodium carbonate solution. 13 minutes of electrolyisis; white foam forms almost immediately, turning brown toward the end of the cycle.

Obviously the amount of liquid is small in the barrel with the 4mm rod. Draining shows very dirty solution with particles.

I then flushed with a litre of boiling water; using a homemade funnel.

Then I carried penetrating oil wipe through. Then the addition of a scrub with Bore Tech Chameleon Gel;(first time using this); before continuing with the normal clean.

Unfortunately I didn't have the borescope available this weekend (no laptop). But to the naked eye, the bore definitely looks cleaner, bright and shiny.

I will inspect with the borescope next weekend to compare.

It's nice to be important, but it's more important to be nice!

Borescope photos will tell you how it worked. But, does sound promising!

After you shoot it, use a good copper cleaner for the next few times you shoot.

OK that's good. Not picking just thinking ahead. Clown

Looking forward to seeing the borescope pictures as well.

Much improved.

What does the throat look like? Particularly in regards to firecracking. You may not be able to see it without a mirror though.

Good job. It would have been great to see the difference in the bore between each process but I know how easy it is to get done and then realise that you forgot to stop and take pictures!

The Teslong flexible scope with the set of mirrors is pretty decent, that’s what I’ve used to take the more recent photos that I’ve posted. It’s very reasonably priced.

I'll second the Teslong, model 100, just plugs into a USB port.

	My thought based on the image looking down into the breech from the magazine well, is that you slightly over-filled it? Not easy to d I know. I wouldn't mention it except to ask if it was past the level where the barrel & receiver threads end. I'm concerned with the solution wicking down int the threads possibly causing problems later?

	Shamu, The liquid was mid chamber with the rod in place; but bubbles when the current is applied. I wicked off the excess foam and liquid after taking the photo.

	Look forward to seeing bore pics. Very interesting process, but like Britrifles, just a little apprehensive.

	Apologies for the delay getting the borescope pic's. I would mention that this is a cheap (10 Euro) USB scope. So not great quality and no mirror. But it does give some idea of the condition. First photo is how it looked when I first got the rifle. Next is after multiple ordinary cleaning after shooting several times. Not sure of the round count, but probably between 100 and 150 rounds. Finally, after one 13 minute electrolysis, hot water flush and clean, using C4 carbon remover and a kroil type product. The barrel is still frosty; but does show some improvement. A lot of carbon was removed when cleaning. I will use JB Paste to polish the surface. The rifle does shoot quite well; within standard spec'.

	Here is the start of the rifling. I don't think this rifle has bad much use. Evidently, I need to invest in a better scope. But I don't see any obvious signs of cracking.

	Yes I will have a look at the Teslong. See how much it is in France.
