What is the effect that is caused by too much copper fouling in the bore?
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.
Should I remove copper fouling?
Some rifles need some fouling to shoot their best. Copper and/or powder fouling can build up to levels that affect accuracy, however, and so the fouling must occasionally be cleaned from the barrel.
Is copper fouling bad for a gun barrel?
So there you are with a bore that’s free of powder residue and a sickly smile on your face, and it’s time to get down to the real villain, which is copper residue. Powder fouling is unattractive, but pretty much harmless. Copper residue will take away your barrel’s accuracy and wreck your barrel in some cases.
Is WD 40 good for cleaning guns?
Since WD-40 is primarily a solvent it seems to make sense that it would be ideal for cleaning guns. However, cleaning your guns with WD40 is NOT advisable. Using an aerosol solvent simply “shoots” all the gunk into tiny crevices in your firearm, making them even harder to clean and can lead to “gumming” up.
What is a fouled barrel?
Bullet-metal fouling is the result of pushing a relatively soft metal (or metal cased) object down a relatively hard bore at high speed. Metal—lead from cast bullets or copper from jacketed bullets—is rubbed off the surface of the bullet and is left inside the barrel.
Is it good to clean your rifle barrel?
This can lead to rust, fouling, and ultimately a continuous drop in performance as the rifling degrades. It’s a good idea to clean your rifle barrel after every time you shoot. It doesn’t take much time and it can do wonders to extend the life of your gun.
What happens when you clean a copper fouled barrel?
Very often, a copper-fouled barrel will shoot OK until it’s cleaned, and then it won’t shoot worth a damn. The copper has covered up the pits, and when it’s removed, the bore looks like the surface of the moon.
How does copper fouling affect a rifle’s accuracy?
Obviously, copper fouling can affect a rifle’s accuracy. A borescope, while not necessary for cleaning barrels, is one tool that can help cope with fouling by revealing problems not visible to the naked eye.
Why do I have to clean my barrel with JB?
The reason is copper buildup in the bore. It’s almost impossible to burn out a barrel in 750 rounds, and cleaning rod abuse happens very gradually. But copper buildup? J-B is what I use to remove copper too, and it always works, but you have to use it correctly.
What percentage of zinc is in a gun barrel?
Consisting of 90 to 95 percent copper and 5 to 10 percent zinc, “gilding metal” proved to be easier to remove from rifle bores, with fouling normally thin enough that legendary gun writer Elmer Keith called it “copper wash,” saying he’d rarely seen it affect accuracy.
