LaneNebraska,Good report,If you ever find out why 777 acts that way post it for me. I have tried it in 5 of my 14 muzzle loaders and from time to time I am temted to throw the last two cans in the trash, If it was not for the fact some people I respect don't seem to have any problems with it I would give up on it. I have had excellent results with APP also. Lee
