Such a determination would probably need to be ascertained in a laboratory environment.
Otherwise.... pretty much all lore and bullshit. |

I wanted a custom barrel on my Remington 700. I always use JB Bore Past in it, hoping to speed up the process of wearing it out. (actually to remove the copper)
It didn't wear out.

I use KG bore polish on a bore mop to clean up stubborn fouling. A few strokes usually takes anything out. No issues with barrel wear.

I think some folks forget what happens to this family of firearms in the real world. The standard US Army methodology is to scrub the bore with a bronze brush. While bronze is certainly softer than the chrome lined bore, I can think of times when we sat there and cleaned our rifles for half a day. I swear we'd run bore brushes down the tube for hours. I'm not even kidding that we did this all the time. Weekly some times. I am positive I put better than 8k rounds through my issues M4 and probably ran a bore brush through it 2k times. My last rifle qualification in that unit was just like the rest... qualified expert, tapping that 300m target every time.
I guess the moral of the story is, these beasts are a damn sight more tolerant and resilient than people give them credit for. Clean it well and avoid jamming screw drivers and rocks in there. Otherwise, anything designed for cleaning the bore is likely perfectly acceptable. |

Thanks all, that's what I thought... didn't make sense that the resulting "wear" from cleaning with a lightly abrasive solution could come close to firing even one round.

Not to mention running a few TUBB lapping rounds down the bore...
What concerns me is getting any abrasives into the gas system, where it can get back into the bolt. Would do a good flush of the gas tube before shooting after using the abrasive bore cleaner, and if shooting the TUBB rounds, turning the gas system off (which is possible with my Spike cam adjustable gas block), and hand cycling the action. |

You can certainly wear a barrel out cleaning it.

I've been using Flitz, Iosso, or JB over the past 5 years or so. I always put a dab on a bronze brush and just go back and forth a few times. Bore comes out clean as anything. This is over a stainless steel and chrome bore.
I use a bore scope and throat erosion gauge and see nothing wrong in either case except a really clean bore. |

Quote HistoryQuoted: Thanks all, that's what I thought... didn't make sense that the resulting "wear" from cleaning with a lightly abrasive solution could come close to firing even one round. None of the gun cleaners are abrasive. They might have some measure of abrasion but nothing that would harm the bore. I would imagine after so long that Iosso or Flitz would have long ago been sued and clients would have won against them. They would have warnings on their products that you shouldn't be using it at all. I would also say if you're worried about it use something else like Wipeout. |

I would be more concerned about damaging the bore by using too harsh of a bore solvent and leaving it in the bore too long. If it contains ammonia, make sure you follow the directions on the bottle concerning how long to let the stuff soak in the barrel.

Quote HistoryQuoted: You thinking crown damage? Quote HistoryQuoted: Quoted: You can certainly wear a barrel out cleaning it. You thinking crown damage? The rod dragging on the throat is the worst. Dedicated individuals with stainless brushes (and bronze) can actually fret the bore like a phonograph record from really scrubbing it. Crown damage is a consideration, but most people really into over cleaning know about so they’re careful there. The barrels I’ve seen worn out from cleaning have mainly been the rod dragging on the throat and wiping it out from about 5-7 o’clock. |

I use both JB cleaner and polish on some of my rifles and rifled slug guns.
Not every cleaning session, but here and there, it has its place. On less than perfect, factory new barrels, (in my case some rifled slug guns....not always the highest quality) it helps remove any tooling marks in the bore. Not an issue with premium stuff tho. Don’t show that stuff to your BR buddies, they will probably throw garlic at you and try pound a stake in your chest. |

Wet patch it till clean, then wet patch it again and leave sit for 1 hour. My gunsmith (Hall of fame shooter) Thomas "Speedy" Gonzales" did some chamber work for me and could not believe my barrel had 1000 rounds on it. He said it looked new. 3" groups at 600 yds. |

To prevent damage to the throat, always use a bore guide and a 1-piece rod (stainless or plastic-sheathed - which is a religious debate). I like Sinclair bore guides and BoreTech Bore Stix.

Have your friend look at the lenses on scopes, binoculars, etc. These were created with abrasives, so abrasive is not a bad word.
Ironed-on carbon deposits (ahead of the throat) just can not be removed any other way. I have tried the "carbon removers" over night and nothing came out the next day - on a clean patch. Iosso takes care of matters in a few minutes, and my bore scopes reveal this clearly. |

over use will damage the rifling. you can polish the corners away.
look into Gale McMillian and what he has seen with overuse of such product. |

I use 40X on barrels that Hoppe's can't get the carbon out of instead of a bronze brush. I also use it to quickly clean a new barrel. It works great in both applications.
