Ballistics don't match, and his gun was never fired.
弹道学不匹配，而且他的枪根本没有发射过。

It may be used to determine the effects of bore curvature thermal deflection of the tube eccentricity of the projectile interior ballistics data and construction of gun tube on dispersion error.
可用于确定内膛弯曲度、身管热变形、弹丸偏心率、内弹道诸元和身管结构等对射弹散布的影响。

Based on the mechanism of gun erosion of interior ballistics, the method and process of predicting the gun tube life are presented.
