I retrieved and read Army Tech Manual 9-1300-214 on military dynamite: 
 (h) Military dynamite M1, M2, and M3 is a 
 medium velocity (6,096 meters per second) blasting 
 explosive in three cartridge sizes. Military dynamite M1, 
 M2, and M3 has been standardized for use in military 
 construction, quarrying, and service demolition work. 
 The explosive composition is packaged in standard 
 dynamite cartridge waxed-paper wrappers. The models 
 differ only in the cartridge size. Cartridges are 1 1/4 
 inches in diameter by 8 inches long for the M1, 1 1/2 
 inches in diameter by 8 inches long for the M2, and 1 
 1/2 inches in diameter by 12 inches long for the M3. 
 The composition used is: Percent 
 RDX 75 +1.0 
 TNT 15+0.5 
 Grade SAE No. 10 engine oil plus 5 +0.5 polyisobutylene 
 Cornstarch 5 +0.5 
 Desensitized RDX, which is coated with engine oil 
 before mixing with the other ingredients, and grained 
 TNT are used in the manufacture of the dynamite. 
 Military dynamite M1, M2, and M3 is equivalent in 
 strength to 60 percent commercial dynamite. The 
 military dynamite is safer to transport, store, and handle 
 than 60 percent straight nitroglycerine commercial 
 dynamite and is relatively insensitive to friction, drop 
 impact, and rifle bullet impact. The composition 
 remains plastic at 57°C after 24 hours. Military 
 dynamites are odorless, free from nitroglycerin toxicity, 
 nonhygroscopic, and chemically stable when exposed to 
 80 percent relative humidity at 71°C for one month. No 
 freezing occurs in cold storage or exudation in hot 
 storage. Turning of shipping containers during storage 
 is not necessary. 
 Therefore I am clarifying the article. If someone followed the meme that "military dynamite was equal to 60% of commercial dynamite" instead of "Military dynamite ... is equivalent in 
 strength to  ... 60 percent straight nitroglycerine commercial 
 dynamite" too much military dynamite could be used as a replacement for commercial dynamite.
