We shoot Gregg's camera with his grocery store-bought M&P; 10 double-shot assault rifle converted with a scope available online with an adapter to make it shoot faster. (do you know your memes?) https://www.youtube.com/watch?v=gYhA-...
But seriously, we had the fortune to hear the bullet whizzing away and saw it on camera. We often hear these screaming bullets in our videos and they really sound menacing. However, the bullets are NOT travelling very fast, they are just tumbling through the air very fast, which is causing the noise. I am able to get a speed estimation just be observing how far an object moves each camera frame. A 22.lr bullet going 800 mph will travel one foot per frame when filmed at 1200 frames per second. When the same bullet travels 1 inch per frame, it is going 68mph.
The point being, an audible ricochet is not travelling very fast, but an INAUDIBLE ricochet - where the bullet hasn't lost much energy CAN travel a LONG ways. It's the ones you don't hear that you need to worry about, as they say.
