I've just started using this Hoppe's 9 Copper Solvent after using the regular Hoppe's 9 Solvent and gun oil for years. This Copper Solvent seems to do a very good job of cleaning out the copper residue left by other solvent. I shot my Elk rifles the first time after using this solvent at the range. There seems to be a noted improvement in consistency of close groups. Thumbs up!
