Bore scope diagnosis?

Flitz on a BoreTech stiff Nylon Brush or worn brass one if the carbon has hardened, but BoreTech C4 after a shooting session on a mop and soak overnight and don't give that carbon a chance to try and turn into diamond the next time you fire it.
 
Just ordered some flitz from the link provided here. Should be here in two days or so. I have an older boretech nylon brush, and I used the iosso with it and it cleaned it up a little bit, but it's still there. So I'll get some pictures soon. Ordered some boretech eliminator and C4 as well to try out.
 
Just a little carbon, is all. I work JB into a patch, wrap it around a worn brush and add a couple drops of Hoppes. Work it back and forth in that area. Make sure to put the bore guide on the rod first. Clean the bore guide really well after.

How many shots does it take for it to come back?
 
My experience after 3000 rounds approximately, the barrel still shoots and looks relatively good but you get a flyer or unexplained shot. I have set it back and kept going another 1000 rounds,
While I have new one coming. I haven't experience getting some 5 to 7 thousand shot and being in the winner circle. But I do shoot at the higher velocity's. If your not getting 20 to 23 X's you will not be happy.

Boy, that seems like a low round count from everything I've read about the cartridge.
 
You can shoot a barrel forever. Doesn't mean you will be competitive. It may be fine for a minute of deer.
I understand that, but I've read literally 1000s of threads on this forum and others and never heard of someone calling it quits on a barrel with 3000 rounds give or take for a 30BR and then taking even further to "minute of deer." I'm not saying it didn't happen to you or it never happens at all but I think you're an exception rather than the rule.
 
It not calling it quits. Its not winning. If a 30br barrel last 3 years. and set it back and get another year.
What is not to like. I may be a little conservative in round count, or as Speedy said, a new barrel fixes a lot of bad scopes.
 
Hell, I don't know if it got better. Tonight, I used flitz with a bronze brush, and then let it soak in bore tech C4 for a few hours and scrubbed it good. I'm going to let it soak over night with the C4, and give it one last scrub. I shot it a couple weeks ago and it was still shooting same as always — real small. So it is what it is. I don't think I'll concern myself with it any longer. It just annoys me is all.

When I borecope my barrel after cleaning I find very often some carbon like on the picture you posted. Very tiny strings of carbon in the lands. I do not use iosso or other abrasive to get rid of it because it does not hurt my accuracy. I foul my barrel anyway before next match. Like Frank Green said, abrasives should be applied very carefully. i use cameleon gel by boretech which is way milder than iosso or even jb.
 
I like using IOSSO to scrub the carbon ring after a little soaking with CLR.


I find it very effective when I wrap a patch around worn bore brush and soak the patch a little with the green stuff, giving it ~10 full back and forth strokes + 5-6 more short strokes in the first 6-8 inches. Then I run a couple wet patched of Hoppe's (one way) to clean it up, a couple dry patches. . . and done.
that's pretty much how I do it and Hoppes for clean out

do it when the barrel is hot and oil the barrel before doing anything, makes a slurry and helps loosen the carbon I think it's what I do anyway, barrel hot right after shooting coat with FreeAll let set then go with the carbon grinder might get lucky
