It is not a glitch. Probably it narrowly missed the container model while the "hit" is probably triggered by the proximity of the bullet to the container! Anyway what are the chances of this happening again anyway?? And also in real life a sniper bullet could potentially go through a container with no worries. Especially the 7.62 x 51mm  that the tango fires. Even the stronger containers are only made out of 3-4 mm thick steel which is unable to stop anything larger than a rifle .22 LF or a 45 from a handgun......
