cleaning patch residue question

[MildBill]

Hi

the picture in this post is of a cleaning patch from my 223 ackley that was pushed through after the barrel sat with patch out in it for about 10 hours today. this was not the first patch through, that one had some blue from the copper and the dark streaks

The barrel had 15 rounds fired through it. benchmark powder and 55 grain sierra bullets

The question is, is this just carbon residue or am I some how wearing off the coating on my boretech proof positive clean rod.

thanks for the insight

Looks like normal fouling to me....

Powder/Primer = Black
Carbon = Brown/Tan
Copper = Blue/Green
Layered Carbon = Brown/Tan - that can have traces of Copper as well

the thick black streaks are what made me scratch my head in wonder what it was.

I have seen it before while cleaning rifles,

I thought I would ask.

Looks normal to me. I like to let my guns sit and soak. It gets the stuff out of the little nooks and crannies. The rougher the barrel the more it will get out by soaking. Matt

I like to let them soak, my opinion on the patch pictured is thats carbon layed down in the grooves and your getting close..

You talked about the coating wearing off the rod! I hope that is not the inside of the patch?

To me it looks like powder fouling... If you are cleaning from the breech with a good bore/rod guide with good technique I wouldn't be concerned about wearing off the coating on your Boretech rod. If this is an M1A and you are cleaning from the muzzle be careful because it is very easy to have a sharp crown shave off small amounts of the coating on a coated rod. Either way if it is the coating opposed to powder residue you would be able to tell the difference by feeling it.

Bill, if you wear the coating off that jag you will be able to see it I think, and the patches will always come out with blue on them regardless of barrel cleanliness if you are using copper solvent. That nickel coating should be pretty durable as long as you don't scrape it off, but a little mis-alignment of the jag/rod and a sharp crown could do that I suppose. FWIW, I had Denny Phillips make me some of his Ivy rods with integral jag & won't be using anything else in the forseeable future.

i have seen this MANY times and think i know what causes them. carbon collects in the angle between the land and groove...basically a 90 degree angle. when it comes out you see two streaks close together and if you have 4 lands, you will see 4 of the 2 streaks close together. these streaks eventually clear but will take some effort as this carbon is the thickest and most resistant to removal. solvent is inadequate whereas the bronze brush will in time loosen it and the patches gradually come out clean. abrasives, jb, take out a lot of the lands edges before getting to this "baked on" carbon. there is a product, dyna tek bore coating, that significantly lessen carbon adherence to the bore. this streaky carbon MUST be removed.

Try to find someone with a bore scope and only then will you know where the residue is coming from and what it will take to remove it. Brush and clean with Bore Shine and then evaluate with a bore scope, that's the fastest and most effective way to clean.

If that's all you got out of the barrel following 15 rounds and 10 hours of a Patch Out soaking, I'd switch to a different solvent like Butch's Bore Shine [BBS].

As soon as I finish with a relay or a match I run a few patches through my custom barrels and see much more Powder fouling than that. To get rid of the Carbon fouling and Copper that was resistant to BBS [and a little Sweets 7.62], I follow up with one or two patches of JB paste followed by BBS to get all the JB out.

Cleaning a rifle properly takes a little work but things can be done in a few minutes vice almost half a day that apparently can have one wondering if the job was even accomplished at all. When I'm done my patch comes out white.

If you wipe down your cleaning rod between patches, which you should always do, you may see a little of a coated rod's finish come off initially but that subsides with use. With my Dewey rods it did. Good shooting.

there was more than that, the patch in the picture was not the first one through.

I re-treated yesterday evening and ran patches through this evening again, they had the same kind of streaks as the picture

I then re-treated with solvent again, will run some more patches through either in the morning or when I get home tomorrow evening.

Have you tried 6 or 8 strokes with a bronze brush before the patch, then a second patch?
