A tower‐type drop‐weight tester is used to characterize mechanical properties of LOVA gun propellants ata nominal strain rate of 300 s −1 . This study is a comparative evaluation of two testing methods, namely the original and the newly introduced one, that differ in the initial experimental setup. The results of the evaluation show that with the original testing method, the specimens are strained nonlineraly which, at times, has led to an anomalous compressibility reduction of the specimen. The newly introduced testing method improves the strain rate control and uniformity in addition of having a very good results‐reproduction capability.
