[QUOTE="Mikecr, post: 1401000, member: 1521"] Slicks provide huge friction(traction) for NASCARs. But there is an extreme energy loss with this, the tires melt into grease, as they burn up. Just opposite, trains function by virtue of very little contact with rails, which greatly reduces friction. A well performing corvette needs dead between. This is your barrel. W/resp to copper. A slick bore causes so much friction that jackets overheat, and copper wipes off into the bore surface (much like a hot NASCAR slick on pavement). And what causes too little friction(given correct bore dimensions), is roughness that tears away at passing bullet jackets. Again, increasing copper fouling. Once copper builds to any constriction, shots throw. [/QUOTE]
