Nathan at Aimed Research, who specialize in ultra-high speed gun photography services and equipment rental (I did not know this was even a thing … I have lots of ideas for posts with this kind of equipment), sent us this photo of a .243 bullet. Nathan wrote …
This photo demonstrates the terminal ballistic fragmentation of the Federal Power-Shok 100grn .243 projectile upon impact of a soft target such as the Clear Ballistics synthetic ordnance gelatin block.
The image exposure was 1/2,000,000th of a second (0.0000005 sec), illuminated with a total of approximately 150,000,000 beam candela of light. The image was captured with a simple Canon Rebel XT by Aimed Research.
Note the multiple small and large projectile fragments.
