Good question. Was it a still image, or a frame from a fairly fast video. Originally, I was thinking like 240 fps, but I’m not an expert at such things. Math below, just me figuring.
Every attempt I’ve ever made to capture a bullet in action has failed.
How far does a bullet fly in 1/240 of a second?
A .223 coming out of an AR-15 leaves the muzzle at around 2600-2800 feet/second. Of course, it loses a little bit of speed as it flies through the air, but it should remain supersonic well past this range.
So, let’s say it’s slowed down to 2000 feet/second. That’s 200 feet in 1/10 of a second, and 20 feet in 1/100 of a second. 10 feet in 1/200 of a second, and a little less than that at 1/240 second.
All that tells me is that either the projectile lost some speed (perhaps when it encountered the ear) or the muzzle velocity was a lot less than what would be typical.
It’ll be good to know just what caliber it was and what kind of gun. Typical AR-15 is .223 (almost the same as 5.56 NATO), but the 300 Blackout is popular too. It’s a 30 caliber that can be chambered in the AR-15. It’s larger, heavier, and slower at under 2000 feet/second. They make sub-sonic 300 blackout ammunition (around 1000-1100 f/sec). Bigger bullet, heavier, and slower. In theory, it can be silenced (or at least suppressed) more easily than most rifles because the bullet doesn’t produce a supersonic boom as it flies through the air.

Pathetic.
That’s why I want to know all about that camera.
The math changes if it was capturing video at 1000 frames per second.
(And it would need serious light gathering capacity, so I want to know about the lens as well.)
It’s that PA humidity that makes it possible to see that supersonic bullet path. Any Kodak SLR that can shoot 1/500th could probly stop it. No need to get all digital and fancysmanchy about it.
