Both will remove copper fouling,but can't be left in the bore,longer than the instructions say too! Allways use a good bore preservative (oil) after using either of these. I use Kroil,and you CAN leave it in the bore overnight,then a dry patch,or two and your ready to go! Ron PS. use a good carbon cleaner,first,then go after the copper fouling!
Pretty good advice right there.
I use Sweets, but MT Extreme or Barns CR10 also work. I'm thinking amonia's amonia.
Wipeout's good too. As stated above, leave it overnight for best results.
FWIW,,, most Savages mine copper like it's their job. Doesn't seem to hurt the accuracy, but it can sure be frustrating.
Another reason I don't own any.
For normal maintanence on "normal" barrels, my old standby is a 50/50 mixture of Kroil and either Shooters Choice or Butches.
Luck
