I'm trying those black coated .45 auto bullets from Precision for a Wilson 1911. The load is 4.7g. Titegroup under 200g. swc. After shooting 170 rounds the barrel bore is badly coated with the black from the bullets. The grooves have so much black built up in them that its flaking. I let Hoppes 9 soak the barrel for 2 days then used a bore brush on it. Much black came out but a lot remains. The black is just smearing around.
Any ideas on what it takes to get the black out? Thanks much VonBarky |

Take a bore brush, wrap it in a few strands of Chore-Boy all Copper Scrubbing pad. Run it through the bore a few times and presto, clean as a whistle.

You're not supposed to shoot those bullets with TiteGroup. It burns too hot and melts the coating.
I might actually be tempted to try something like naptha or acetone - something that will dissolve plastics. I'd imagine the Lewis would work, too. Mind you folks, he's removing the black moly coating from the bore - not lead. |

I was slightly mistaken, a mix of HP and vinegar.
This is right from the page from Precision Bullets. Easiest way to do it if you've got a SS barrel. CLEANING YOUR BORE Normal cleaning methods will work for our bullets, but sometimes the coating will stay in the barrel. If you cannot remove the coating with traditional cleaners—Shooter’s Choice, Breakfree, etc.—see methods below. The Lewis Lead Remover from Brownells works great on heavily fouled bores. Stainless steel barrels only 50/50 mixture of hydrogen peroxide and vinegar in a jar Make a hook out of a paper clip Remove barrel and lower into mixture with paper clip hook Soak for 20 minutes Remove barrel and wipe off excess with paper towel 1 pass with a bore brush 1 pass with a tight patch Flush out under sink with water Dry off, patch out, and oil Carbon steel barrels Take a “Chore Boy” stainless steel scrubbing pad Cut off a spiral portion from the pad Wrap around brass cleaning brush Apply Breakfree CLP—5 or 6 passes through the bore Patch out with favorite cleaner Dry the bore and oil |

I found that Titegroup produces lots of smoke and moly/polymer deposits with "black" type bullets. Titegroup has a high percentage of nitroglycerine and burns relatively hot compared to many other pistol powders. Use a single base powder like the Vihtovouri N320/340 or Solo 1000 for lead or polymer/moly and you will find the bore stays much cleaner and there will be a lot less smoke. |
