What kind of bore cleaning brush do you use and why.
Are the nylon stiff enough to get the though spots off?

I have friends in metallurgy and machine tooling and they said; for bronze to damage a rifled barrel, you would have to run it through a few hundred thousand times.

I use bronze.

Maybe, but I don't have the patience to keep at it that long.

Bronze all the way!

Have a number of each, but always reach for the bronze ones.

Use Bronze UNLESS you are using a Copper solvent which might actually dissolve the Bronze brush. For Copper solvent you should use Nylon brushes.

Note: Bronze has copper in it and will be dissolved more quickly when Copper Solvents are used. Some of the Copper Solvents tell you to use Nylon Brushes only when using their products.

There are many different bronze alloys, but typically modern bronze is 88% copper and 12% tin. Alpha bronze consists of the alpha solid solution of tin in copper. Alpha bronze alloys of 4–5% tin are used to make coins, springs, turbines and blades

I use the bronze brushes even with copper solvents.
They are cheap. I buy several at a time. Some are sold in packs.

Bronze here too.
Anything else just does not seem to do the job....

Thanks guys and gals, bronze it will continue to be. Always wondered if continued use of the bronze would result in any ware on the barrel

I used to use Bronze and it took Me a while to figure out that the Cleaner was eating the Brush so when I put a Patch through the Barrel it would come out black even though the prior one was clean.So I use Nylon now unless the Barrel is extremely dirty and then finish with the Nylon Brush.

I must not be doing it right cause my bronze brushes don't get eaten that fast.
I buy them by the bagful anyway.
I swab the bore with solvent, let it sit awhile, run a clean patch thru, then brush several strokes.
Run a light solvent patch thru to clean. Repeat as necessary.
Dry brushing is just as or more effective than wet and is not quite as messy.
I have also found that the plastic brushes are not nearly as effective at cleaning tough deposits in the chambers and throats.
The only thing I use plastic for is titanium cylinders and then ignore some of the harder stains.
Like so many other things in life, everyone will find a way that works for them.

Bronze brushes have been used for decades, and with stronger bore cleaner formulations for copper fouling than what is current available now due to what the "environmentally friendly" laws allow, and those brushed have stood the test of time.

I would be more concerned first about a bore cleaner's ability to damage the gun's bluing as it dribbles all over the place, than it's ability of being strong enough to dissolve the copper in a bronze alloy brush.

But putting that aside... I prefer bronze brushes because the bristles are finer and more numerous than those on a nylon brush, so they really get into the nooks and crannies of the rifling lands.

I use bronze, because it's stiffer and cleans better.
The subject of bronze vs brass alloys is twisted, convoluted, and often confusing.
There are bronzes that contain zinc and/or lead, and even some that contain no tin at all.

I use nylon bristle brushes on aluminum frames/receivers and for air gun bores. I normally use nylon brushes for .22 rimfire bores, too.

What would Jim Cirillo do?

A squirt of brake cleaner on your bronze brush after brushing w an ammonia-type cleaner seems to neutralize the ammonia that breaks down the bronze. I've found the brush lasts a lot longer.

Brake cleaner also works well to degrease the cylinder chambers.
I degrease chambers in any gun I intend to shoot in the next day or 2.
Stainless or chrome plated chambers I may do right away during cleaning.
Blued I leave the chambers protected with residue until the last moment.
Brake cleaner WILL completely destroy a plastic brush however

For rifles and handgun barrels I rarely use brushes any more. The chemical cleaners are effective enough you don't really need them. I do use Chore Boy strands wrapped around a bronze brush if I have been shooting lead. Cylinders are a different story and I use the chamber brushes from Brownells.

You probably already know this, but don't dip your brush in your bottle of cleaning solvent. It will contaminate the solvent over time.
