Abstract：The effect of pressing pressure on the efflux performance of the powder shell was studied by density test, crushing pressure test and armor-breaking performance test. The results show that with the increase of the spinning pressure of the powder shell, the density and crushing pressure of the powder shell increase, and the penetration and stability of the jet penetration of the powder shell fluctuate obviously. When the pressure is increased to 110 tons, the penetration depth and stability of the jet reach the best state.
