The camera would be outside the box pointing at it from the shooters POV. Doesnt mater where exactly as long as it can focus on the target, few meters away.
Me too.
Oh I see, but what would you aim at?
Pretty much this idea but a little less.... complicated.
I have a camera that will shoot video at 1000fps and this wont capture a 12ftlb pellet in the air at 20 yards.
