If you’re interested in firearms or high speed photography, watch this video. A .45 caliber pistol is recorded at 73,000 frames per second. I was surprised to see a jet of gas come out the muzzle well before the bullet. The fastest firearm high speed video I had seen prior to this was 30,000 fps. That one was used as an input to a solids modeling program used by a gun manufacturer.
