I see that a lot of the odorless gun oils on the market that are geared for deer hunters contain mineral oil. Is this the same "odorless and tasteless" mineral oil that is found in the pharmacy and used as a laxative? I am just wondering because it should be a lot cheaper to buy the laxative version rather than the small two to three ounce "hunter" formula. I realize that mineral oil may not be the best rust protective out there but I like to apply it to my guns every other hunting trip or so just to prevent them from rusting. I don't want to apply a better preventative such as Break Free CLP or Weapon Shield during hunting season because it will spook game. Thanks for any comments back.
