C4...working?

I've found Shooter's Choice MC-7 to be better than anything else I've tried.

No, it doesn't smell good. In fact, it stinks. Wear nitrile gloves, and put the dirty patches in a zip lock bag or your reloading area will reek.

No, it's not a magic solvent that dissolves everything effortlessly. If you're scared of using a brush, then good luck. You'll need it. With ANY solvent.

But my borescope tells me it works better than anything else I've tried. And it's a long list of failures.

My theory has been that for everybody who shoots a rifle, there a “ custom “ cleaning regimen. “ So far I’ve seen nothing to dissuade me of that!

oops should have said yes but no. Yes solvent first to clean out the gunk then take a look with borescope to see how much copper and where and to look at the carbon job ahead of you. Then the JB and elbow work. I put my rifles in a big vice on workbench in the shop for the stroking work.

Same here except I've been trying Holland's Witches Brew after the solvents and am quite happy with it. Someone mentioned it is very abrasive. Use accordingly!

I'm not gonna mess with anything that has that kind of caution. With JB the more you use it the LESS abrasive it gets. From what I have been able to find out the secret ingredient is diatomaceous earth. Very interesting stuff!

A very smart gunsmith told me years ago everyone worries about the wrong end of the barrel. He said the last 10 inches is where it's at. I have come to agree with that.

I've had a Hawkeye bore scope since the early 90's, it was almost a $800 back then but I think it's been a helluva' an investment for my firearms maintenance. I have found some cleaning as you go works a lot better than waiting till it stops shooting. In that time I've never been able to bring back a bore that's been ignored. Also in bore scoping hundreds of barrels I found the soot, the carbon, the copper, and the erosion were all in the first 10 inches of barrel. Perplexed by your post.

I have a Hart barrel on a 6ppc with around 1100 rounds or so on it. It has developed a copper problem about 3" ahead of the chamber. I can only remove it by using Iosso on a nylon brush. I figured out that I need to clean it after every target for it to shoot well; patches and bronze brush with Butches, then a nylon brush with Iosso and patching it out with solvent. The target below shows when I realized I can't shoot more than one target, plus foulers/sighters, without cleaning.

#1 three test shots, looks good. #2 five shots, looks good. #3 two shots, not good. Clean barrel. #4 five shots, good. #5 three shots, what the heck is going on? #6 two shots, it finally dawns on me that I need to scrub the barrel after each target. #7 & 8, good. #9 I'm not sure what I did there.

I have only had a horoscope for maybe at years. For many years , maybe 30 or so before that I was showing guys theirs clean gun was not. Yes a borescope will verify what you think is happening. Do you need a borescope to have a clean gun. No, but it is nice to know. You notice I did not elaborate on the wrong end of the barrel statement nor will I. I seldom go more than 15 shots without cleaning. But does it shoot better surgically clean and shiny as opposed to maybe a trace here and there but no carbon ring. I don't think so . One other thing I will say, I equate nylon brushes to busy work.

Anybody used Prolix before?
Best stuff I have ever used.
I run a patch down wet with Prolix
Dry patch out
Wet a bore brush with Sweets, and give it about 5 passes and then give it 5 mins to work on copper
Repeat this procedure once more
-------------------------------------------------
Sparkly clean every time
-------------------------------------------------
Then follow up with a wet patch of Hoppes to protect and dry patch out and put it in the safe for next session
