This post is to correct previous bad math.

A pellet at muzzle velocity of 900fps will take approximately 0.3sec to reach a 100yard target. Recording this flight time in 30 frames per second will get you 9 frames recorded, in 240 frames per second you will get 72 frames recorded. When you edit the recording for this 0.3 seconds to 1/8th speed, 9 frames recorded changes to 1.125 frames displayed per second and the 72 frames recorded changes to 9 frames displayed per second. Another factor when recording is focus. Your camera will be focused for the 100 yard shot and thus the majority of the flight time will be out of focus and possibly out of frame. The more frames you can record during flight time will give you a better chance of actually capturing a recording of a pellet.
