| I didn't know to "break in" my target rifle when I first bought it (.308 FNH Patrol Bolt Rifle). I've only put 100 rounds or so through it. It is very difficult to clean the copper fouling out of the bore. Should I use the Tubb Final Finish lapping bullets, or just clean it as well as possible and start the break-in process? |

I like the Tubbs Final Finish kits and use them often. The kits have saved a few barrels and rifles from the For Sale section of my gun safe. YMMV |

Quoted: Just get some JB bore polish and clean that copper out. No need to push abrasives down a new barrel. Let it lap itself. Yep. I mix the JB bore paste with some Kroil and it works like a charm. First patch of Kroil only, let it soak in for 10 min. 2nd patch using the rougher grit JB/Kroil and do about 10 passes back and forth like they suggest 3rd patch using fine gril JB/Kroil and do about 20 passes Then another kroil only patch, dry patch, and a patch with CLP, dry patch. |

I clean the barrel as well as is reasonable, then I use JB.
Pay special attention to the throat of the barrel. This will be the crustiest part. As you go back and forth with the JB patch you will feel the roughness in the throat area and as you work on that area, you will feel it start to smooth out. |

Just get some JB bore polish and clean that copper out. No need to push abrasives down a new barrel. Let it lap itself. Do this first. Try some powerful bore cleaner first (Sweet's) and follow the directions which state "no more than 15 minutes" inside the bore. Neutralize the bore cleaner by clearing it out Gun Scrubber or similar solvent. Then clean the bore with regular (I use Hoppes) and follow up with JB Bore polish. Follow the directions. You'll be amazed at how much crap comes out of the bore. Never fire any rifle with a bore that has been chemically stripped of all lubricants (Gun Scrubber/brake cleaner) or you will get copper fouling immediately. A lightly oiled patch followed by a dry patch will leave enough lubricant in the bore to protect it until powder fouling can form a film between the bullet and the barrel. Stripped bone dry barrels will always copper foul. If deep cleaning methods fail then try Tubb's product. I have used his Final Finish bullets on commercial barrels that were sub-standard and it improved them. I have used Final Finish on match barrels that stopped shooting because of high round counts and it brought them back to life. I would never use Final Finish on a new barrel unless all other options have been tried. It's not intended to improve match grade barrels, it will cause more harm than good. It's a very good product to improve standard production grade barrels that have accuracy or fouling problems or to breathe new life into a nearly worn out match barrel. |

I would say that youre well past the "break in" state @ 100 rds expended. I personally think its BS with today's manufacturing processes. I would just clean it with dedicated solvents and oils. |

This is the best stuff I've ever used for getting copper out of a bore. It's water based, so there is no issue with leaving ammonia based cleaners in too long.
KG 12 There was a test someone did where they took barnes bullet and put it in different copper removers. KG12 removed 60-90% more than any of the other copper cleaners. This stuff is the real deal. |
