Bore scope my barrel

I liken this along the same venue as I do with those carbon marks on the face of a revolver cylinder, cooked carbon. The easiest and thus the quickest with less effort and time to remove this I have found is using a product called "Lead Away". It's thick yellow color embedded cloth made by Kleanbore and it's designed to remove lead and carbon build up. I use a Parker Hale Jag in the next lower size caliber and wrap it around the jag and start stoking. Depending on severity, it may take some strokes to remove it completely but it will come out. NOTE: if this is a blued rifle do-not use it on the blued pr case harden components.

Everything else I've tried usually requires soaking and scrubbing that work but it just takes more time and effort. I have tried the following and they work but it requires more effort to really get the tough carbon out:

- Shooters Choice and Kroil mixture [60/40];
- Patch-Out/Wipe-Out: This is a chemical solution so I use nylon brushes. This stuff removes carbon, copper and hard powder fouling. However and do NOTE: Do-Not use this with any other cleaners as it may interact and cause etching.
- Slip 2000: Carbon cleaner only but be careful you don't get it on blued or case harden finishes.
- Sweet's 7.62 is a excellent copper remover but I don't know how it is with carbon. If left in the barrel too long it has been reported to cause etching due to the high ammonia concentration.

I've never tried Holland's Witches Brew or Ed's Red but I've heard they are good cleaners. I have some Frog Lube cleaner but I haven't tried it yet.

Hope this helps

Does the bullet ride much on the grooves anyway?

I think when you look at a fired bullet it shows land, grooves, the tight 90° turns, etc. (radial rifling of course is not 90°).
I don’t think a single part of the barrel misses any of the bullet on its 50,000 psi ride.

That is another thing never been really happy with this barrel , not getting the groups that I think I should be getting .

Give me an idea what you’re shooting. And what distance. What size 5 shot group at 100 yards do you think you should be getting?

Thorroclean has abrasives in it.

So does FLITZ

OK I never had this problem till after I shot some Barns bullets. They have a much longer bearing surface . So from now on I'll stay with Berger, BiB,and PRP bullets . I'm shooting a custon barrel . AND I NEVER HAD CARBON build up like this before , like I said I have a bore scope and use it after every cleaning . You can at all the POP-CORN all you want LOL LOL
I'm shooting a 222 and not getting enough groups like it did with the old barrel and the same make custom barrel . And only shooting at 100 yds that is the only distance that I have to shoot.. I'm not like the rest of you fantastic shooters that shoot 2" inch groups at a mile with a 22 rim fire .

like I said I didn't like using abrasive in it .

You don’t “like” solid copper anymore. You don’t like using abrasives to fix your screw-up. You never liked this barrel. You won’t like a suggestion to try Sweets to get that copper that might underly the carbon, so fuggetaboutit

Where did you get that I don't use Sweets ? WTF ??? fuggetaboutit . You must be the guy that shoots a mile with a 22RF and gets the 2" groups ?? So what ? you like to make smart aleck statements that mean nothing that help nothing ?? Thanks !!

If I cleaned my current 11 centerfire rifles that much they would never shoot to POI or group well until I re-conditioned the barrel with several shots. Furthermore, I would have first shot flyers in abundance.

What is your shooting performance goals / requirements?

I have it, "You Can't Always Get What You Want, but Maybe You Can Get What You Need".

I'll offer some help.

Stop the aggressive cleaning with aggressive solvents. Put the bore scope in the closet. I strongly suspect that your accuracy issues are NOT due to a "dirty" bore. If fact, I believe your aggressive cleaning is aggravating the issue.

Re-condition the bore with about 20 shots, fire slowing without overheating the barrel. Clean the bore with a simple solvent, Hoppe's 9 or Shooter Choice. Use a bronze brush, no harm, Dewey. I assume you are using a high-quality cleaning rod and bore guide.

Do some elementary load development testing with the powder and bullet you like and have on hand. This combo should be components that have a history of good performance for the caliber of rifle you are shooting. See "Accuracy Loads" in various reloading manuals.

Once you have a load than meets your performance requirements. Practice and keep a record of your performance. Depending on the caliber, clean every 50 or 60 rounds with a simple solvent and bronze brush.

Precision and accuracy have many fathers. Bedding, loads, shooter skills, scope, bench set up, etc.

I'm done .

Don't get frustrated. See my post on the help I am offering. What do you have to lose? Try it.

So how much load development have you done with the new barrel and what have you tried? It's unlikely cleaning or the initial cleanliness of that barrel is your issue. Mine look much worse after a day of shooting and still hold together as expected the next, with or without cleaning. And when I clean, I use abrasives every time and in 20-30mins it's perfect. I used to spend hours trying to patch out a barrel with solvent only and it's just a huge waste of time in my opinion, get in there, get it done and be ready for the next one.

If you have exhausted multiple options of powder and bullets, which would be known good choices in your cartridge, and all other variable have been checked over from scope rings and bases, the scope itself, bedding job, trigger cleanliness and function, bolt cleaning and relube, action screw torque etc... You possibly just have a bad barrel. If you can screw on your old barrel, shoot the old load and it groups as expected, contact the manufacturer and see what they will do.

I've been shooting my gas guns quite a bit lately...particularly my 16" set up with iron sights to add some flavor in my life. I've put a few hundred rounds thru it since I brought it out of the safe, where it was cleaned thoroughly down to metal. Exclusively using h335.

Last week when I got home I noticed the barrel was still warm, not hot but luke warm, so for s&gas I oiled up a boresnake and gave it a few pulls....I ran borescope thru for a quick peek and low and behold, it removed almost all the visible carbon leaving only copper, interesting. Last evening I went out and shout another 120 rounds thru the 16" and about 50 thru an already heavily fouled 12.5 sbr., again running the boresnake thru the warm barrels and once again almost all carbon removed.

It makes sense that heat softens up the carbon some making it easier to remove but had no idea to what extent. I am going to try this method again with a pretty carbon fouled bolt gun and hopefully see same results, but so far using the boresnake as an intermediate quick step between deep cleans on a warm barrel is seeming to work.

How far into the bore were those pics taken?

How far into the bore were those pics taken?

Most were at and just forward of the lands the last one was closer to the gas port on the 12.5.
