Can you over polish the bore of a barrel.

[mikecr]

The lands at 6 o'clock or so on some of my rifles show more erosion than those on the top (not concentric) and as expected accuracy has suffered.

Tubb's Throat Maintenance System (TMS) for this.

Looking at a Savage barrel with it's finish and you wonder how does this thing even shoot.

Savage barrels are indeed very rough and foul quickly. Yet my students have managed four national championships with factory Savages. Beauty is as beauty does.

 

[fyrewall]

320 grit actually

Seems like a start for gauging surface roughness.

Would it be safe to say that if I’m using Flitz, or Ioso or JB Bore Compound to keep the carbon build up in check on a 6BRA with 1,400 rounds through, it doesn’t copper foul, and still shoots groups like this that I haven’t hurt anything (yet)

You are correct, these threads are filled with half truths, misinformation, and just outright being wrong!!!

I use Flitz Bore Cleaner. Liberally. That stuff is amazing. I stopped using brushes, and I simply use Butch's patches, Boretech Eliminator and Flitz bore cleaner, and I can assure you my process leaves my barrels shooting very well.

Borescopes don't lie... If you are shooting and not getting that carbon out with something (I suggest Flitz) your barrel will start to shoot worse and worse.

I also suggest Tubbs TMS bullets for break in and shoot one every 100 rounds to keep the throat ironed smooth. Also an amazingly effective product... (heresy)

What I see being posted are individual experiences that may/may not work in your circumstances. I like it because it reveals approaches that many times I’ve never considered. Your choice to pursue... or not. In your case, that group strongly suggests what you’re doing is working just fine!

You missed the dot all 5 times!

 

[WIB3]

Guess I had better stop using Flitz in my tumbling media, could be wearing my cases thin.

dang, and now I know why

 

[WIB3]

This product also removes carbon quite well. Works very well on your custom clear coat, I’m quite certain it doesn’t hurt your barrel.

A pencil or stick of chalk won’t let you write your name on a smooth glass pane. The pencil simply refuses to “foul” the smooth glass. A chunk of glass cut by a rough wheel will easily accept lettering though.

Galling on the other hand stresses both metal surfaces and might be the “bad thing” that can happen. The bullet will get the worst of it a few times but the steel barrel’s surface is being stretched and deformed. That probably has something to do with alligator skin in the bore.

HBN and moly are messy and - perhaps because of that, not a lot of shooters actually write on the forum that there’s any benefit they can envision. That’s always been curious to me because we could all intuit I’m certain, that if we had to sit down on bare posteriors and be pushed the length of a basketball court, no one is going to pick either rough or dry, for surfaces. That equates to the perfectly polished bore and 10w30.

 

[WIB3]

No rifling process leaves a perfectly smooth finish. If there are some who claim that they are lying. I personally have never seen it in the scope. Some might hand lap at the factory but they are never perfectly smooth. Flitz, Iosso and JB will never make them smooth. If certain manufacturers will not back that then let them provide accurate data to back up their claims. I have cleaned gold and silver weighing it on a semi-micro balance with absolutely no change in weight.(.00005) This was done over 20 cycles. Stainless is much higher on the Brunel scale.

 

[WIB3]

The Sartorius MSA225S-100-DU Cubis does not lie.

 

[jelenko]

I thought that copper fouling came mainly from the jacket getting torn in the throat, the copper transformed into a plasma, then deposited later down the barrel.

Is this correct?

Thanks

 

[jelenko]

I don't know the answer to your question, but I can tell you that you could clean all day long for rest of your life and you will die before you remove any metal with JB. Use it freely.

What is the 'black' that shows up on the patch? I had assumed it was the slightest bit of metal.

 

[WIB3]

Black is typically carbon, blue is copper. Don’t get confused by coloration on your patches caused by the jag. I use bore tech patch perfect jags. Bore tech eliminator is also a wonderful product.

 

[jelenko]

Sorry - I meant the black from polishing with JB, Iosso, Flitz.
I was wondering what it was if it wasn't metal.

 

[WIB3]

If you apply Flitz to any metal, steel, stainless,aluminum it will turn black. Interior or exterior. It’s no different than using mothers or Speedy. It’s removing “dirt” not actual metal. When using a bore cleaner and the patch comes out black it doesn’t necessarily mean that you are removing metal.

 

[WIB3]

Some swear using C-R, it’s an acid. Ask those who use it to let it sit overnight on a piece of aluminum? Have them put it on their Panda action overnight. But it’s safe in their barrel.

There was some testing done on boat hulls I remember.... specifically on personal watercraft...they were were doing speed trials and the craft were marginally faster with that super smooth gel coat "broken" or scuffed with a light abrasive... Scotch brite if i remember correctly...not necessarily apples to apples...but interesting.

With high performance boat hauls scuffing the pad surface has to do with eliminating the drag associated with water's surface tension. I don't believe the same applies to barrels.
