How Long; How Far?
 



Bullet is 300g Deep Curl with a muzzle velocity of 1880 fps. The questions are: What is the time of flight? How far from rifle to jug?

Winner gets an autographed copy of SEMISANE' ramblings, first edition.

Note a portion of the jug, flying toward the camera, at the lower right just outside the water, with a reddish tint.

Is the mic at the jug? No way to judge it. By the time we hear the sound it hits the jug.

How did you come up with that?

That was cool, but I have no idea.

Let's see if I'm close and then I'll share. I want that collection of Semi's ramblings.

That was 60 yards, .0748 seconds. There were 3,854,291 water droplets produced. :D

HINT: Camera records 30 frames per second. Pause the video, and count, using the arrow keys to move between frames.

It doesn't matter what time the primer pops. All that matters is when the bullet leaves the muzzle. I don't think you can tell that from your video. So you can't count frames to determine the time of flight. Tom.
