What bore cleaner do you use ?!

My tests showed KG12 to remove copper. CLP and Boretech carbon remover work nest for me. I'm starting load development for 6.5 mm cartridges this year and I plan to experiment with Boretech and KG 12.
 
Both - got about 225 rounds down it and still difficult to clean
Make sure to get some GOOD brushes. The Thoroclean system works very well but you may have to work it depending on how hard the carbon is and how thick the copper is.

If it's really bad you may be better off with IOSSO paste or JB bore brite to get it completely stripped clean.

This is my 7 PRC after cleaning it with ThoroughFlush and ThoroughClean. It took about 15 minutes. The rifle hadn't been cleaned since hunting season began last year and it was shot by 3 different people and their hunts as well. 72 rounds had been fired through it.
 
I just ordered some Thorough Clean and the flush kit.I have a good system and it works well but always looking for a better mouse trap.
Not really better but faster I guess.Less smell also.I also use quality brushes as well.
