The easiest mixture is just plain old fashioned windex - the blue stuff with ammonia... Ammonia is the active agent and it is a metal cleaner - neutalizes T7 residue on contact.... It is also and excellent cleaning agent to get most of the material out of the barrel prior to the real cleaning. Makes the job really easy.
Make your patches just barely damp one patch will last for several shots. If you make them right you will not even need to dry patch... the warmth of the barrel and ammonia will rapidly evaporate any moisture. But it might take you a couple of trys to get the patches just right...
