What do you use to remove carbon? ... what really works?
JB BORE CLEANING COMPOUND!
Comments on JB Paste and abrasives by two well known sources:
"I personally believe in the use of JB Bore Cleaner... I use it after every yardage. 3 to 5 tight fitting patches with JB will get the powder fouling out... I do a full cleaning before I use JB and also after I use JB, to make certain I've got all the JB out of the barrel. ... Tony Boyer"

Krieger Barrels Inc,: Q&A
Q: Will a paste-type bore cleaner such as J.B. hurt a barrel during cleaning?
A: No. There is nothing that we can find that shows that it will harm the barrel provided you use a rod guide and refrain from exiting the muzzle.
--------------------------------------
Instructions received from Krieger along with my Krieger barrel: Break-In and Cleaning, Under Cleaning:
"Abrasive cleaners work well. They do not damage the bore, they clean all types of fouling (copper, powder, lead, plastic), and they have the added advantage of of polishing the throat both in 'break in' and later on when the throat begins to roughen again from the rounds fired. One national champion we know polishes the throats on his rifles every several hundred rounds or so with diamond paste to extend their accuracy life."
-----------------------------------------------------------------
Most people worry about copper; they should be worrying about carbon. How do you find the carbon ring?
1. Pull a NYLON bore brush back through the bore, from muzzle to breech.
2. You'll feel lots of resistance on the rod when it hits the carbon build-up.
3. That's where you need to scrub with JB paste.
And don't forget the area at the the end of the neck chamber!
