Is it ok to use Break-Free CLP or Rem Oil in rifle/pistol barrels after they have been properly cleaned? I believe I read a while back (can't find it anymore) that products with Teflon shouldn't be used in barrels. After I read that I switched to using only Hoppe's #9 and Barnes CR-10. I leave a light coat of Hoppe's #9 in the barrel until the next trip to the range. I primarly use the CLP and sometimes Rem Oil on the exterior finish and in the action (bolt) only as of right now. If I shouldn't be using CLP or Rem Oil, should I stick with #9 in the barrel or get a product like Kroil?
