The numerical calculation model of interaction between bullet and sniper rifle was established to deeply study launch process of bullet, which is based on nonlinear finite element theory. The model coupled calculation program of bore pressure and numerical calculation of the launch process, which can reflect the real relation between bore pressure and bullet motion. Engraving process and the subsequent ballistic process were combined in this model to ensure integrity of internal ballistic. The barrel pre-bent condition which is caused by gravity is also considered. The model was a comprehensive consideration theory model to calculate launch process,the accuracy was proved by comparing experiment and calculation results. The force conditions, stress-strain, swing angle of bullet and vibration of muzzle under the gravity field was obtained by calculation, which revealed interaction mechanism of bullet-rifle.
