I would agree with your assesment, shame he used chipboard looked like a old kitchen worktop so no way to gauge the power as you could break it with a solid punch. At that range the trajectory was obviously not good, he had a lot of drop off as his shots were widely spaced verticaly.
My other halfs brother is a hunter by trade & now uses a crossbow, its his job so hes a very good shot. Even so he reckons you really need to get the drop on anything over 60-70 metres as hitting a moving target past that is nigh impossible. With the heavy bolts he uses it will take down a deer at that range & I can remember he said the shot drops a foot at 70 metres.
