In reply to comment: any educated guestimates here? (see in situ)

I would guess (without watching the video again)

about 1/2 mile away.

There are 5280 feet in one mile and the M230 has a 2641 feet per second muzzle velocity.

This doesn't account for wind, humidity, air temp, ammunition temp, etc.
