I know this should be in the bowhunting forum but I am sure there are archery hunters here. I used to shoot at cardboard boxes with flatten cardboard stuffed in one box. It worked but pulling the arrows out was not fun. So I took the idea of those commercial targets that use layered foam pads and set my cardboard target on its side. So I was shooting at layered cardboard. It actually worked. It slowed down the arrow and pulling the arrows out is easy.
