What Type Of Brush Should I Use For Gun CleaningNov 04,2022

In the shooting community, there are many varying viewpoints on the topic of bore brushes, each with what appears to be its own supporting data. Your understanding of what is excellent and why will rapidly become puzzling if you quickly surf the internet.
Brass brushes were very common; this practice has roots in muzzle loaders. Those barrels had been cleaned! The materials and solvents used to clean firearms have evolved over time, but have we perhaps continued old practices?
On the lead inner, the majority of bullets feature some sort of copper jacket. Some residue of copper is left behind when fired at high speed through a close-fitting barrel. If nothing is done, it will pile up. Some will refer to this as a fouling barrier, while others will refer to it as a bearing surface, although that is the subject of another article.
Assuming you intend to remove the copper, you will usually use an ammonia-based chemical to remove copper fouling because ammonia dissolves copper without harming steel.
Brass is an alloy made up of copper and zinc.
But using a brass brush could result in two problems. First, the solvent used to clean the copper can also corrode the brush, shortening its lifespan and deceiving you into believing the barrel has more copper than it actually does by leaving blue/green stains on your patches. Even if you keep cleaning, you feel like you need to do more.
Moreover, copper is much easier to remove than carbon and typically requires only a nylon brush or, in some cases, a jag and patch.
Use nylon thus for copper. Less chance of mistaken observations and less damage to clean equipment.
In general, bronze brushes won't harm the barrel, so you can use them to clean your rifle without too much concern.
