A substantially inert composition has mechanical properties simulating corresponding properties of an energetic composition which may include a nitrate ester and may include a particulate organic energetic fuller. A nitrate ester is replaced by a mixture of inert materials having densities less than and more than the density of the ester and present in proportions such that the mixture has substantially the density of the ester. A particulate energetic Organic filler is replaced by a particulate inert organic chlorine derivative having substantially the same density. When the ester is 1,2,4-butanetriol trinitrate, which may function as a plasticizer in an eastomeric energetic composition, the less dense material is a non-volatile ester, such as dimethyl phthalate, and the more dense material includes a bromoaromatic derivative as in a mixture of pentabromodiphenyl ether and an aryl phosphate. When the particulate energetic organic material includes the energetic particulate material cyclotetramethylenetranitramine the chlorine derivative is 1,2,4,7,8,9,10,13,14,14-dodecahydro-,1,4,4a,5,6,6a,7,10,10a,11,12,12a-dodecahydro-1,4,10-dimenthanodibenzo a,e cyclooctene. With this chlorine derivative, the inert composition may include particulate aluminum in about the same proportion as the energetic composition.
