Q. Will steel-jacketed bullets wear out my barrel?

Steel-jacketed bullets are always plated with a layer of copper to help protect the bore of the gun. There should be minimal extra wear in a rifle with a chrome-plated bore, but many people are of the opinion that steel-jacketed bullets should be avoided in non-chromed barrels.
