Tikka Carbon Ring Question

[General RE LEE]

I haven't bore scoped my barrel in hundreds of rounds. It looks like I got a carbon ring. The rifle is shooting well so I'm undecided if this is something I should tackle with Kroil and JB Bore paste with a Dewey chamber rod.

Thoughts? Again, rifle is shooting well.

That's one of the problems with those bore scopes, now you know about it. LOL Years ago, w/o it, you would have done nothing until you saw signs of over pressure or accuracy degradation.

That said, I'd clean it. Been using Free All, available at O'Reilly's Auto Parts stores, the past month or so. Makes fairly quick work of them. Get rid of it before it becomes an issue or causes trouble when it really counts.

Just my opinion as I'm learning and growing in my knowledge and abilities along with everyone else.

I take a carbon cleaning rod in a drill and let her eat. Rifle bore is nice and shiny after.

Soak a patch with Hoppes 9 or Boretech C4 and push it just up into the throat and let it sit. In an hour or so scrub some with a brush and repeat until it's mostly gone.

Well, it's certainly there. I'm in the camp of clean it now before it does affect accuracy. It's easier to take care of now when it's just starting to layer up. My SIL's 243 was destroying brass because proper cleaning was ignored at that spot.

Another vote for cleaning it. There is no down side.

I could be wrong, but that brass colored stripe in the middle of the black makes me think it's already thick enough to be interfering with the case mouth.

I'd definitely do some soak and scrub if it were mine...

 

[General RE LEE]

Soaked chamber with Hoppes and used JB Bore Paste applied to patches wrapped around and undersized bore brush. Got most of it.

On to my Tikka CTR 308. I got it good with the JB Bore paste. I'm wondering if that black ring is carbon cause it will not budge. Everything else was cleaned up.

Sure looks like it. As others have suggested, let a patch soaked with your preferred carbon remover sit in there for a while and then hit it with an oversized bronze brush in a drill motor. Should come out clean as a whistle.

This one is super stubborn because I soaked it with Hoppes and scrubbed, Butch's Bore Shine and scrubbed and then hit it with JB Bore paste and scrubbed.

Try Bore Tech Carbon remover or Free All penetrating oil. Same way, soak and scrub with bronze brush.

Any other theories on what this band might be? Stain? No way that's carbon cause I've hammered it hard and zero change.

Carbon ring go bye bye in my 6.5 CM Tikka (1500 rounds)
