In this paper migration theory and techniques related to the high-energy TEGN gun propellant are presented, and some methods determining the migration of RDX are analyzed and compared. As a result, chemical and thermal analyses are employed associatively to test the content of RDX in different position of TEGN gun propellant stored different period. The antimigration capability of TEGN gun propellant making use of two different granularity of RDX is also been studied.
