Who needs an action camera mounted on a rifle or a helmet to show the shooting accuracy when you can follow the actual flight of the bullet with the Bullet-Cam. Vortex Optics and Hornady collaborated to develop this bullet with an action cam. Shooters can then watch how the bullet flies via their mobile phone though we wonder how many can afford destroying action cameras each time they pull the trigger  and the video says it costs US$99.99 for a box of 10. That's US$9.99 per Bullet-Cam.

Bullet-cam to watch the bullet fly in Bullet-Time. It is one of the better produced April 1st stories we've seen this year. ;)
