Hi Guntech,

For those following, a second application of Guntech eliminator:

I noticed some oddly square patches of black stuff (Carbon?), that I'm going to try remove with more focused brushing on the next go around.

There looks to be a granule pf extruded powder in the video, did you lose a bullet and dump powder into the chamber at lone time? have you checked your bolt lug area with the scope for powder that is compressed in there?
Cat?
I had the same issue a while back with a rifle I acquired , that is why I asked. Turns out there was some caked up ball powder ( 748 maybe) that was in there, we eventually got it out after some soaking and compressed air, and some soaking of solvent. However, this rifle had been cleaned several times before , and of course you wouldn't see it unless you scoped the lug area itself!

Bullets seated too far out, brass not sized enough, some sort of burr in the chamber, etc
Start with a really through cleaning of the chamber and throat with something like carb-out. Then measure the jump to your lands and seat bullets 1/100th back from that to the ogive. Then inspect your chamber and throat with a borescope if you’re still having trouble? Just suggestions.

There's a novel idea...
To those looking for updates, I have been having the most success using Accelerator and Patch-out, method being the one described by the company. One patch with Accelerator, followed by a nylon brush with patch-out. There are chunks of carbon coming out, black flakes that were visible in the borecam, are now coming out clinging to the dry patches. I'll post some pictures and a video in a bit.
Something I am curious about, but doubt I can solve, is that this rifle I purchased used, having seen about 25 rounds. I have since put 200 or so rounds through it. The carbon caked in this rifle, seems to indicate a MUCH higher round count then what it should be. Either that, or the Staball 6.5 I primarily used at first, was just that dirty.
Looking forward to the day that the bore looks clean, and I can start to dirty it up again..

Update, no idea how many times I've run stuff through the rifle. but have definitely made some progress. Was making gains with patchout/accelerator, but that died off, patches coming out clean when borescope showed carbon. I tried CLR a couple times with little effect, and the stuff scares me, so didn't put too much effort into it. Currently making massive gains with carb cleaner. Spray it down the chamber, let it sit, send a bronze brush on a drill in and target the area, then patch it out with patchout till they come out clean. As you can see in the video, theres metal showing where there used to be carb. You can see all kinds of black gunk I've knocked loose in this process.

Last update hopefully, probably head to the range tomorrow. After the above post, 3 more rounds of carb cleaner -> bronze brush -> accelerator -> patch out on nylon brush -> patches till dry, the carbon ring is gone.
Hornady ELDX factory now loads and ejects effortlessly.
What a journey. Hope she still shoots!

Good news you got the ring out. Just be careful with the drill. I have never really had a carbon ring problem myself, but I have a barrel with a rough bore, and used JB bore paste to clean it up good. Worked very well. ( no drill )
Now you will be able to see how long it takes for that ring to develop. I also don’t trim to min length and usually end up somewhere in the middle of the spec. What does your fired brass neck look like? Is it very sooty?

Of course it will !!
I’m back!!! So, it turns out I got most of the ring out, but not all of it, there’s a super stubborn ring that’s built up where the case neck ends inside the bore. A CGNer sent me a video of his clean bore, so in comparison I got some work ahead of me still. Trying the find Iosso or jb bore paste is brutal when you add shipping IF you can find it in stock.
So the day went like this, super stoked to be able to cycle factory eldx rounds. Headed to the range.
First three shots of Berger 130 hybrids pushed by varget were a relief!
Switch to barnes factory with this result:
Then the factory eldx - first three was the Center group, adjusted and next three were slightly spread up to the left.
Went out for a drive looking for a bear, parked the truck, loaded, and went for a walk, bolt was sticky extracting the unfired cartridge, and visual inspection shows the same damage I attribute to the carbon ring.
Got home, borescoped, and decided this black bit is a ring I didn’t get out. Probably causes quick build up
After another bunch of cleanings, slow progress seems to be happening, with bits of carbon showing up on cleaning patches. Mostly using carb cleaner at this point
