ThanksWipeout Tactical works even better on carbon.

Correct me if I'm wrong,but a carbon ring in the "neck" area of the chamber would have to be around .015" thick,or as thick as the neck of your cartridge case,to cause bullet sizing upon firing. I just dont see that in the video of the chamber.I am of the school of thought that carbon buildup is back, copper is good. I do not clean my barrels bare, ever. After every match (100-200) I run 1 patch wet with Hoppes #9 and a few dry patches just to remove dust and keep the carbon down. I use a bore guide and nylon brush with a cotton patch wrapped around it. I never let the cleaning rod run on the crown.
I think a lot of people wear out their barrels with too much scrubbing. Abrasives are bad. Running cleaning rods across the crown will cause uneven wear of the crown. A bit of abrasive to smooth fire-cracking once in a blue moon is about all that is necessary.
Carbon rings in the throat are extremely detrimental to accuracy and pressure. You are basically squeezing the bullet smaller to pass through the carbon ring making the bullet sloppier in the bore. Gas blow by is also increased. Carbon buildup in muzzle breaks is also extremely detrimental to accuracy.
Both are easy fixes with patience. I run a wet patch of carbon remover past the carbon ring and leave wet over night. If very stubborn, I leave the wet patch in the bore on the ring ahead of the chamber for a while. Trying to speed up the process with mechanical means is not a method without a lot of risk.
just my 2 cents.

I think brux is button. shouldnt make a difference with this many rounds though, right?Is it a cut rifled barrel or button rifled
Love to see a borescope of that. I am a visual guy and a lot of people say it cleans them to "bare metal" but I have never seen a bare metal cleaning since I got a borescopeI just got done cleaning the carbon and copper out of a 1950's Model 70 338 Win Mag. my go to carbon cleaner is Bore Tech C-4, my go to copper cleaner is wipe out-- patch out, then again, I have such good results with Montana and Hoppe's, nothing does it better than Wipe out products. this means the "accelerator" before patch out on nylon brushes and soak the bore in the two products together. then if it is really bad, like the 1950's M-70, I use a really unusual combination I discovered by complete accident.
I first put down accelerator, then patch out, after 20 minutes I start in with J&B Bore Paste and keep agitating until the patch out is a gel. then run a patch through and start all over again. nearly 70 years of copper and carbon build up came out in a couple of days between repairs on other guns. the gun was supposed to be a 1/2 MOA gun and has degraded to 1.5" gun last week. they wanted a new barrel and I asked if I could try to save the barrel.. I did, the gun now shoots 1/2" groups for me at 100 yards, that is not C to C that is edge to edge. 200 yards it is 3/8" C to C, 300 yards it is 1/2" C to C. this is one hell of a nice 338 Win Mag. I am going to offer to buy the gun when the guy comes to pick it up today.
Thanks. Couldnt remember without google. I always think the B barrels (bartlein, brux, etc) were button and they arent.Brux are cut.
Yes they areBartlien are cut as well.
