Butch's Bore Shine is what I am using now. I have used the Kroil/SC mix,Hoppes #9,JBs,Sweets,Prolix,Corbins. Even the Outers Foul Out ((for extreme copper fouling-works great!) I don't shoot moly coated bullets. I have found Fastex and it is great! As for the Bore-Snake. I wouldn't use it for cleaning only. But for prairie dog hunting it beats hiking all the way back to the rig to clean the barrel. We pull it through every 25 rounds. Not the answer to a spotless barrel but keeps the fouling down to stay in the field shooting longer. But since I found fastex I won't need to carry the snake anymore. Hey George, is your book published yet? Great title! good luck! I'm out.
