Carbon Ring - In Pictures

[HIC3540]

Hi, I have been a long time reader of the forum and took the plunge to join. I wanted to give back on my first post. The carbon ring is a discussion that is always talked about but seldom with pictures.
I am going to update this thread with pictures as I remove the carbon in this barrel. This rifle is a 6.5 PRC with a Muller Works barrel. The rifle has 250 rounds down it at this point.

Carbon is building but I did not take it seriously:



After roughly 60 round string this is how the barrel looks now after Eliminator and C4 patches only.


Verified bullet interference with dykem:


I will be trying the popular methods and ending with Isso and JB's. I will keep the thread updated with the success/failure of each method.

A 60 round string on a 6.5 PRC? No wonder that throat looks a little rough already.

 

[HIC3540]

Well it was 60 rounds spread out over a day of shooting groups. Poor wording!

Are your before and after pics with the c4 eliminator, backwards?

I use the Dykem Markers. Just search that in Amazon. You can also use layout fluid or regular sharpies if you want.

They are not. The C4 and eliminator come out completely clean through this barrel as it looks in the bad carbon pictures. I have not brushed it so will update pictures through the rest of the process.

It looks that way because I used the same color when verifying bullet seating depth.

Do you use a bronze brush with C4?

Did you allow the specified dwell time of C4 in the barrel?

What does the target tell you (i.e. has the accuracy declined)?

This was just my initial patch out with Eliminator and C4. I will update with brushed pics and finally what it takes to get any remaining hard carbon.

The accuracy was fine and the SD/ES was not jumping around. I only noticed some scratches on an ejected round, I try not to over scope because it leads people to over clean from what I have seen! In this case I miss timed the round count or it did not like the rounds seated back .010. Not sure on that yet.

For those interested this is the rig. I have a few barrels for this one, but working with the PRC this month.

I am still trying to learn to love the lab radar. I need to use it more, but I still only trust the MS while in load development.

Get a 7mm bronze brush and a chamber length cleaning rod. Put a little C4 (or any 'carbon' remover you desire) on the brush and run it in until you fell it hit the freebore. Twist it while giving it some short strokes of under an inch and you will have that ring out of there pretty quick.

Thanks for doing this. We look forward to your updates.

Good pics and nice looking rig!

Push your reamer in there, and gently turn it by hand.

No. Dont do this.

Too late Dusty, I already did it. And, Heaven forbid, it still hammers.

Hawkeye shows no issues, or scratches where they shouldn't be.
