I have been using Barnes CR-10 and also used bore foam and both seems to work well. I do this outside as it is a bit messy.
1 Remove bolt
2 place muzzle down on rag, vertical
3 apply lots of cleaner to chamber and allow it to find its way to muzzle thru riflings
4 let it soak for about 30 minutes
5 patch it out
6 KEEP DOING THIS UNTIL THE PATCHES ARE CLEAN OF POWDER AND COPPER BOTH (no green, blue, or black)
7 apply oil or Hoppes as normal in the barrel
8 run a dry patch thru it to remove excess oil
I have not seen any issues with the solvents hurting any finishes but always try to keep them off of the other parts of the gun. I do this on all of my bigger rifles but my Tikka 270 is the worst, followed by my Sendero 270, not sure why, but these two also shoot the tightest groups when clean.
