I'll be doing some test shots with my pixel at 1/8 speed, with different rounds vs incandescent bulbs. .45 is about 830ft/s, so at 1/8 speed (240fps) it's moving about 3 feet per frame. 240fps video might not be enough. 7.62x51 is about 2800ft/s, or about 12 feet per frame. I would need about 30,000 fps to capture 7.62, and about 10,000 fps to capture .45 We'll see how it goes. Worst case you get to see it disappear from decently close up.
