Stubborn Carbon ring

Seems my Savage B22 has developed a stubborn carbon ring.

I notice this winter accuracy starting to drop off. Despite always keeping it I thought clean.

Over the winter I got myself a bore scope and took a peak inside the old savage. And it had a nasty carbon ring. Despite my efforts and soaking in hoppes 9 bore cleaner then brushing. The carbon ring although broken up a bit now still remains.

Have some bore tech c4 coming to give that a go but any other advice be more than welcome.

I don’t really need this rifle as I think I going to run my CZ this year for competitions (be my first year not running the savage). But I do love this rifle and want to bring it back to its former good accuracy (.974”avg WITH SK LR)

Tinybear, I'd wait until you get the C4, then put a patch or mop Soaked with C4 in the chamber area. I would avoid Iosso or JB just because it is abrasive, even tho just slightly - repeated use will 'add up'. Using a nylon brush w/o C4 would take forever IMO. You could use a brass brush - if it has a brass core, Not steel - but I would only run it by hand, Not in a drill. Just a few rotations should do the job.The chances for 'too much wear' could cause your chamber to get 'too loose'. I have a B-22 FV and since I got C-4 (3-4 yrs ago) I don't use a brass brush at all on it, just the nylon brush w-C4. I clean the Bore w-C4 also, then plan on 5-10 fouling shots before shooting 'for record'. Usually those fouling shots are pretty good but improve a bit anyway. I don't compete (no comps within 100 miles), just a personal challenge.
JMO, but this works for me.
 
With .22LR the best solution to the development of carbon rings is preventative action. When this is done they never develop.

The preventative action taken by serious shooters such as those in ISSF (Olympic style) and RFBR typically involves cleaning after every range trip usually with a brush and a good solvent, not necessarily a specific carbon remover (most solvents get rid of fresh carbon). These shooters don't worry about carbon rings because regular cleaning ensures they don't develop. Many will clean during range trips.

ISSF and RFBR shooters understand that bores are quickly and easily restored to accuracy with fouling shots, typically no more than a dozen or so when the bore is cleaned to bare metal. There's no advantage to not cleaning.

As always, use a good quality rod and brush with a properly fitting bore guide.
 
Hoppes is a perfume - not a barrel cleaner.

I follow the Womfat technique as he described in his youtube video on 22lr cleaning.
For the chamber, he recommends wetting a patch in a proper cleaning product like Boretech carbon eliminator, putting it on a jag or undersized nylon brush, inserting into chamber, and leaving it there for 20 minutes up to a few hours.
 
some people have had good results using GM combustion chamber cleaner part#993026. others have reported decent cleaning with thorroclean (correct spelling). I think insite arms stock the thorroclean, but not 100% sure

Carb Out is the best IMO, and let it soak a few hours. Then add more before you scrub and let it soak again for another hour or two.

Light scrub with a nylon or brass brush and repeat if necessary. I've never had to repeat more than once to get it all using this method.

JB Bore paste would work too, but it's abrasive - let the chemical do the work for you.
 
Have to put in a good word for Hoppes ...

I have a 102K rounds thru my Vudoo and have only ever used Hoppes and a plastic brush in the chamber. Bore has never been brushed.
Still shoots as good as new. Yesterdays F Class target was 400-31X with 40 rounds measuring .501 inches ES and .142 inch mean radius. Not the best but not bad.

It gets cleaned after every use. We don't have to over complicate this.

Tinybear - Just one more thing. I rarely have 'soaked' a chamber more than 1/2-hour with C-4, a couple times went back for a second-try but Never 'hours' or 'days'.
And Grauhanen is right about 'keeping ahead' of a ring. I clean after Every trip, even if I only shoot 20-rounds. And I notice troubling build-up after ca 100 rounds or so if I shoot that much.
PS - I usually take 3-4 rifles so not a lot of shots on each in one day.
 
" used properly " is the Key; if mis-used it can wear excessively, esp in the chamber. A loose chamber is not conducive to accuracy 😉

I Usally use Thorro Clean and Iosso paste to decaf on my barrels . I just shot 135 rounds out of my 6 GT and it’s really fouled up with copper and Carbon . I’m gonna try BORETECH PRODUCTS this cleaning session and see how they compare !
I will let you know . RJ

This is a rimfire thread, RJ.

You can run your choice of lead or copper down a rimfire barrel or a centrefire barrel, and it seems to me that the bullet metal has more to do with picking a cleaning strategy than the type of priming behind it.

That said, this thread was focusing more on the carbon removal side.

Yeah, but carbon deposited in a 60k psi event is a lot different to remove than carbon deposited in a 24k psi event. Totally different solutions.

Also, centerfire barrels only last a few thousand rounds, so cleaning methods that wear the barrel are not a problem. Whereas in a rimfire that is expected to last 100k rounds, you don't want to wear it out from cleaning.
