Capturing projectiles at 100k+ frames per second allows us to visualize aspects of the firing sequence that are otherwise invisible to the human eye.

This is because the bullet will exit while the barrel is pointed somewhere different than when the shot was initially fired. Much of the shot’s point-of-aim orientation can be maintained through consistent marksmanship fundamentals and recoil management techniques. However, most shooters are not likely capable of managing it to less than 0.001″ for
