Best carbon ring cleaning routine for tight 22LR chambers?

[JCN]

I’m having issues with my JP22 with a tight chamber and carbon ring plus lube deposits making the first chambered round when cold bind.

Basically what he described.

What’s your fastest, most efficient cleaning procedure if you didn’t care about durability… just reliability of function?

I’m thinking soak with CLR (which is what I use on carbon clogged MPX gas expansion chambers) and a brass jag plus patches?

[farscott]

My process is not fast as I usually let the firearm sit overnight. I basically plug the chamber and pour Kroil into the chamber. Let the rifle sit muzzle up overnight in a metal bucket in the garage as I hate the smell of Kroil. Brush it out the next day with a nylon brush patch wetted with Kroil and then swab it with patches until dry. Lube to protect chamber.

This is modified from a faster more abrasive process that uses JB Bore Cleaning Paste wetted with a few drops of Kroil on a nylon brush from a .243 bore. Rotate brush in chamber. Wait fifteen minutes or so and use dry patches to get the crud out. Once dry, lube the bore with your usual lube.

I have a Vudoo Gen 1 with between 10 and 20 thousand rounds through it. I was thinking about getting it re-barreled even though it's said that you can't wear out a 22 LR barrel.

Then I saw the video posted by Greg Roman of Vudoo. I followed his suggestions and I have my accuracy back better than ever. As I was typing this I began to think it sounded like an infomercial. :)

Bore Tech C4 is what you are looking for. I put some C4 on a 22 bore mop and insert it into the chamber I let it sit for a few minutes while I brush the bolt etc. Then I spin the mop in the chamber a few times and remove it. Then i run one patch wet with C4 and then 3 or 4 dry patches and I'm done. I no longer brush the bore. Some times I insert a nylon brush in the chamber after the wet bore mop and spin it a few times if I think there has been build up. If you have a lot of build up you might do this procedure a couple of times and use the nylon brush.

This stuff is like magic. I've been using it in the chambers of my 22 revolvers to help easy extraction.

[JCN]

farscott and BN thank you, gents.

I’m going to amend my process based off the feedback and try the bore tech on the bore mop and see how that loosens things up. I’m also going back to using a bent bore brush as a chamber flag while on steel challenge stages.

I use an oversized bronze brush, about a 24-25cal. My M17 is notoriously tight and that was the only solution that would work in the field (no time for chemical soaks).

Oversized brush. CLP/oil of your choice. It's all about the elbow grease. I mean, if you were an insane, OCD type, you could do the "dip" (50/50 solution of white vinegar and hydrogen peroxide), but it's dangerous IF you're not smart about it (it's not hard to handle this safely). Scrubbing pads like Choreboy (https://www.amazon.com/Chore-Boy-811435002145-Scouring-Scrubber/dp/B007VGICGK/ref=sr_1_3?crid=3GAEXDBLOLQA0&keywords=choreboy&qid=1688048749&sprefix=choreboy%2Caps%2C68&sr=8-3) on your .22 brush with oil will also work.

Does anyone use a boroscope to check their work?

I’m thinking of trying different techniques and trying to get a sense of how little time I can spend and get it taken care of.

I bought a Teslong bore scope specifically to look at the carbon ring on a Vudoo barrel.

As far as removing the carbon ring, I chucked a nylon brush in a drill and went at it with Bore Tech Rimfire Blend.

[JCN]

So I can put solutions in them and soak bore mops.

Then put the mops in storage.

Going to run some empiric tests on how long to soak in what chemical and how rapid build up before failures in a couple of different rimfires.

Went to the range today to test a little bit with the 22LR rifle…

I had pretty good luck with CLP and brass brush on a HOT chamber.

Even after 1-2 shots, the chamber is warm enough that CLP starts smoking.

I soaked it on a big swab and let it sit and work in a little.

Then brass brushed it.

Subsequent shots felt very crisp and not sluggish like a dirty chamber.

Crispest it’s been for a while.

So I’m thinking that maybe I let chemistry work on my behalf and get the carbon before it bakes in.

I had previously used a 22LR bore brush as a chamber flag and I’m definitely going to do that again.

But probably warm CLP it too.

It seemed to work really well.

A year or two ago I got ankle-deep into 22lr precision at 50 yards. Bought a nice Bergara B14r, handful of mags, a bunch of Eley...man I have literally not had as much fun at the range for as long until I got that thing. I could easily blow two hours just poking ever tighter groups of holes into paper. You could get super zen on it if you wanted to...

Anyway, one of the happy fun things about getting into new hobbies - RESEARCH! We all love research, right?

A great TTAG article about 22lr bore and chamber cleaning (https://www.thetruthaboutguns.com/a-guide-to-22lr-barrel-care-for-the-precision-rimfire-shooter/)

The thread I found that link in (https://www.snipershide.com/shooting/threads/interesting-rimfire-cleaning-theory-and-method.7131689/), and it has a bunch more good information in it as well.

I bought a fixed pistol-length bore rod and a bore scope specifically to deal with the carbon/lube ring. 22lr brush with a good carbon cutter and a mop, just in the chamber. For the rest of the bore, I just run a quick boresnake down it for cleaning...that's it, no solvent, nothing like that.

Hopefully that helps some!

Evil_Ed and BN thanks a bunch!

Hearing it from many sources helps.

Definitely looking forward to the C4 on mop technique.

I ordered a boroscope and it’ll be fun to experiment!

Don’t quote me on this, but I think this is the wifi version of the $60 one.

For $89.

From what I can tell the difference between the two models is that the $99/129 version is rigid and the $60/89 one is floppy?

Thanks and it looks like you’re right. That’s what I get for trying to look at it on a phone instead of waiting until I got to something with a bigger screen.

I’m using the same method recommended by Greg @ Vudoo. After having a bad experience on another rimfire rifle with the carbon ring, when I got my Vudoo I want to avoid having one again. So now instead of cleaning once a brick, I now clean the chamber area with a bore mop soaked in Bore Tech C4, let it sit for approx 30 mins, scrub the chamber area with a nylon brush, then patch it out. I’m not really going after the rest of the bore, letting the “good seasoning” do its thing.

I have not had the afore mentioned problem with the carbon ring in the Vudoo yet (knock on wood) and accuracy is good out to 300 yds+.

I need to get a Teslong but I’m kind of afraid of the rabbit hole I’m likely to go down once I can see what’s going on in there….

Have you compared the Boretech C4 to their Rimfire blend? I've had good results with the Rimfire blend but haven't tried the C4.

Yes, I've used the Rimfire Blend in the past. I used to use it and clean the bore with a brush each time. After seeing the info from Greg Roman, I changed to using C4 only like he suggested.

Another story. ;) I don't remember what cleaning method I was using but I had cold bore flyers in my Vudoo. One time I was shooting a very casual local long range match on private property. There was a low spot in the range and the land owner was allowing the road department to dump dirt from their ditching. When the dump truck would show up we would cease fire and allow them to go down range to dump. A few minutes later we would proceed shooting again. I had cold bore shots after the wait every time. There were several interruptions during shooting. With Greg's C4 procedure I don't have cold bore shots.

There are a million ideas about how to clean your rimfire. Just go online to some of the rimfire forums and search. If you want to really stir things up, go ahead and start a new thread. :) The experts and fudds will come out of the woodwork.

I'm now using the C4 plan on my rimfires. As I understand it, Rimfire Blend will clean out the "seasoning" from the barrel. I shoot mostly rimfire long range or PRS type matches. If I was shooting 50 yard bullseye matches I might use a different cleaning method.

My CMMG barrel, shot suppressed and not cleaned yet.

And then my JP…

Are these tool marks?

I’m wondering if carbon ring explains the cold bore hand cycled rounds that bullseye pistol shooters and GJM and Mas described. It is notable that the carbon does soften after the first shot as people here have noticed.

Would be interesting if C4 took care of this on pistols… especially dirty ones that don’t get cleaned much… or even when cleaned might still retain the carbon ring.

Oh man… I’m loving this thing. I get data and can get results on experiments… I was warned!

Tomorrow going to check carbon in increments of 50 rounds.

And see if the CLP and brass brush when smoking hot chamber will mitigate the ring.

Did the experiment today and hot CLP brushing works pretty well. Not perfectly, but in the field… I’ll take it.
