Copper fouling

The tornado brush is made of stainless steel and should never be used in a stainless barrel.

You are correct that the brush is made of stainless steel. It is built to minimize damage to barrels. I find it very effective and use it when fouling gets out of hand. Other times I just use a regular brush.

I will use a wet patch in a good powder solvent followed by a rince with Brake Clean, then household ammonia to remove the copper when fouling gets out of hand. After the brake kleen rince a patch usually comes out clean, without the rince, it can take four or five patches before they do not come out discoloured.
 
I try and keep copper to a minimum, and with well made barrels it is easier.
The biggest single thing is to clean before the copper gets too heavy.

However, if the rifle is still shooting the way it is supposed to i just clean fouling with Amzoil or Mercury Power Tune.

Don't use a lot of brushes, patch mostly, with Hoppes Bench rest.

Here's a question - how do you guys know when "the copper fouling gets out of hand"? :confused: Not being sardonic or anything - just posing a question.

The best way to minimize damage to a stainless barrel,is to never use a stainless brush of any kind as galling can be a problem.
 
Sweets has 5%ammonia in it. I've seen it in all the shops around here. It's a black plastic bottle with a red cap.

Just got a call back from the gunsmith. He used some product that I've never heard of and said it came out asfter a good soak. I'm picking it up tommorrow and will give more info then.

Thanks for everyone's help, it's appreciated.

When I start to get one or two flyers that I haven't called the shot for, it's time to clean.

Butch Bore Shine!

I use Butch Bore shine, available in most guns shop even at Lebaron.

Strong smell of amonia and works very well like CR10, maybe a little milder.

I let 1 hour in barrel then wipe. A lot of blue/green on patches. I don't like brushes for copper removing even brass ones.

Your groups will sometimes get larger and you might start getting flyers if the copper fouling gets bad in a barrel. Some barrels do not foul with copper as quickly as others.

I shoot cast bullets and in some barrels removing the copper fouling will reduce groups from six inches or more to less than an inch, if you're and have a good load. Get the copper out of other barrels and it just allows them to foul with lead. If you are shooting cast and get lead fouling you have an alloy, velocity, lube, sizing, rough bore, or combination of the forgoing issue.
It takes patience to sort it out. Gas checks on cast bullets and a quality lube that has alox in it coupled with velocities kept reasonable will reduce lead fouling to almost, if not, zero.

Copper jacket bullets are fun, accurate, and predictable, and easy to get good accuracy. Cast can be a challenge.

Do ammonia based copper cleaners have any negative effect on stainless barrels? Is it possible to leave it in too long?

Thanks

Ammonia can be left up to a half hour in a modern steel barrel (not damascus). I usually use two ten minute soaks with the barrel heated up by running boiling hot water through it first. This is in a well ventilated place.
The second soak should have a very limited amount of blue (copper) in it and a patch should come out clean. Rince with hot water, then run an oily patch to seal the bore - or it will rust.
