Yes, it is normal to have 3-5 frames of video distortion after recoil. Once the gun is shot, then 2-3 of the initial frames are taken as the pellets are traveling through the barrel, then the ShotKam is engineered to absorb the recoil (the entire circuit board moves) for a fraction of a second. The force of the recoil is approximately 1,000 Gs, so resonant frequencies (vibrations) take a couple picture frames to be absorbed by the electronics.
The ShotKam takes 100 pictures every second, so the distortion is a few milliseconds, then you will notice the clear photo again. Some guns do have more gun debris than others, but typically changing cartridges does not make a noticeable difference.
