What causes copper fouling in barrel?
No matter how a barrel is manufactured there will be microscopic holes in the crystalline structure of the steel. Copper will collect in these voids. Because like metals tend to “stick” to like metals, more and more copper will accumulate until the fouling material is higher then the surface of the bore.
Do pistols get copper fouling?
Depending on the pistol and the ammunition, you can definitely get copper fouling in a handgun. The smoother the bore, the less you’ll see. In addition, some types of ammunition just seem to copper foul worse than others.
Does Hoppes 9 remove copper?
Because chemicals used in black powder are extremely corrosive, it’s recommended to clean the bore periodically during the shooting session. Hoppe’s No. 9 Copper Cleaner easily removes copper residue with a nylon bore brush.
What is copper fouling eraser?
Formulated to virtually eliminate copper fouling, the Hodgdon Copper Fouling Eraser 1 lb. Pistol Powder provides top velocities with clean burning and minimal muzzle flash. This spherical pistol propellant can be used in 9mm Luger, .
Does Kroil remove copper fouling?
Kroil is a penetrating oil and is not suitable for copper removal. That said, sometimes benchrest rifle shooters mix it with something like Shooters Choice for use in barrel cleaning.
What does excessive fouling lead to?
Left uncleaned, fouling can destroy accuracy, and if left for a long time it can result in a pitted bore that will never shoot as well as it originally did and will constantly foul to an even greater degree.
Can you see copper fouling?
No, sorry. Everything fouls. If you look down your bore in good light from the muzzle end, you’ll probably see copper. If you were to look at the grooves and lands with a borescope, you’d see streaks and lumps of it all the way back to the lede, which is the rear edge of the rifling.
How bad does copper fouling affect accuracy?
Copper, smeared on steel, can corrode the steel if there’s moisture present. This creates pits, which do a superior job of gouging jackets as bullets pass over them. Very often, a copper-fouled barrel will shoot OK until it’s cleaned, and then it won’t shoot worth a damn.
Can Kroil be used as a lubricant?
The best gets even better in Kroil Penetrant with Silicone (formerly SiliKroil). Blending Silicone with the legendary Kroil formula results in superior penetration, lubrication and rust prevention.
What is difference between scaling and fouling?
Scaling is a type of fouling caused by inorganic salts in the water circuit of the heat exchanger. It increases the pressure drop and insulates the heat transfer surface, thus preventing efficient heat transfer. The salts are therefore deposited on the warm surface when the cold water makes contact with it.
Why is fouling a problem?
Precipitation fouling is a very common problem in boilers and heat exchangers operating with hard water and often results in limescale. Through changes in temperature, or solvent evaporation or degasification, the concentration of salts may exceed the saturation, leading to a precipitation of solids (usually crystals).
