What is going on??

[BULLET 05]

When I clean my bore on my rifles I have been running a wet patch through the barrel until it comes out clean. Then I run a nylon brush through it several times. Then I run a wet patch back through. The patch comes out black. I do this several times I mean A BUNCH.Every nylon brush through the barrel the next patch comes out black or dark gray. It does lighten a little after doing this process numerous times but still very significant. I was so confused where all the black was coming from I took my guns to a friend that has a nice bore scope. When we looked with the scope we witnessed nothing but shinny metal. THE barrel was virtually spotless. Is the black nylon brush causing this. FYI I always clean my barrels 25 shots and less. Savage Model 25t 22 hornet and CZ .223.

What cleaner are you using? do you shoot moly coated bullets?

Shooters Choice MC-7. No on the molly bullets. I thought it may be the cleaner reacting with the metal or breaking down small amounts of the nylon brush.

How often do you clean the brush? I use 3-m spray brake cleaner. Amazing what will come out of a brush after just a little use.

Could the patch be the problem? Is there a chemical reaction between the solvent and patch? Try another brand of patch or a piece of cotten cloth and see what color you get.

KEEPING YOUR BORE GUIDE CLEAN?

 

[Travelor]

As you shoot a barrel, it develops fire cracks and some barrels have machining marks which traps fouling. Cleaning with patches gets the top of the barrel fouling and the bore brush works on the cracks and machining marks bring the carbon and barrel fouling up. Then a patch picks up the fouling and removes it.

You will drive yourself crazy trying to get all the fouling out of a factory barrel. I know as I have tried it.

You can also pick up a lot of "Black" if you haven't taken the time to totally clean the chamber. That carbon buildup at the 2nd shoulder (at the front of the chamber) can give up carbon as you go back and brush with cleaner.

I try to get this area clean before installing the bore guide by rotating a solvent soaked chamber brush in it and then rotating a bore mop from a larger caliber. THEN I go about cleaning the bore itself so I'm not just dragging more crud in from the front of the chamber.

I like what you said.

A competitor I know got beat by one X at the Nationals at Camp Perry this past year and he had not cleaned the bore of the rifle he used for 2200 rounds!

Go figure!

I don't clean for a few matches, say 400 rounds down before cleaning, and I only clean carbon, don't touch copper until the end of the season when it gets bore scoped, then set back and re-chambered as necessary.
Cleaning ruins more barrels than shooting them!!

Cheers.
